About Avoiding Cancer One Day At A Time

Avoiding Cancer One Day At A Time is an authoritative, good-humored and remarkably practical book on how people can alter their lifestyles and add years to their lives. It describes do-able prevention and sets a needed example for American health care, where research and resources disproportionately address diagnosis and treatment to the neglect of keeping people healthy in the first place. This is an easy read, loaded with practical information - from everyday environmental hazards, to avoidance of carcinogenic lifestyle choices, to a deep and useful discussion of preventive nutrition. And there is a terrific recipe collection which could be expanded into a book of its own.

Avoiding Cancer One Day At A Time (ISBN 1592981593, Beavers Pond Press) may be purchased over the Internet at AvoidCancerNow, at Amazon.com or at local independent book stores.

May Is National Skin Cancer Awareness Month - Tips To Avoid It!

noreply@blogger.com (Lynne Eldridge, MD) — Thu, 01 May 2008 01:33:00 +0000

May is National Skin Cancer Awareness Month!

According to the National Cancer Institute, there will be over a million cases of non-melanoma skin cancer diagnosed in 2008. Thankfully despite this high number less than 1000 deaths are expected, but treatment and worry are considerable nonetheless. Melanoma, responsible for roughly 75% of skin cancer deaths has been steadily increasing from an incidence of 1 in 1500 in 1935, up to 1 in 84 Americans now.Given these numbers despite the widespread use of sunscreen, what can we do to lower our risk?

1. Choose your sunscreen wisely

According to the Environmental Working Group, only 25% of sunscreens are considered both safe and effective. Read The Shady Side of Sunscreen.

2. Cover-up

Looking at the statistics above it is clear that factors in addition to sunscreen should be considered in skin cancer prevention. What did people do differently in 1935 when the incidence of melanoma was so much lower and sunscreen was not available? They covered up! Loose fitting tightly woven clothing, hats, umbrellas, and avoiding the sun during midday can offer protection.

3. Eat your sunscreen

Several foods and dietary practices are linked to a lower risk of skin cancer. Read Eat Your Sunscreen - 10 Superfoods to Lower Skin Cancer Risk.

4. Exercise

Exercise, at least in mice, appears to lower the risk of skin cancer. Read A Run and Java to Prevent Skin Cancer.

5. Remember the benefits of the sun

In addition to warding off the symptoms of seasonal affective disorder, vitamin D produced in our bodies from sun exposure plays an important role in cancer prevention overall. Read Let the Sunshine In - But How Much?

The Shady Side of Sunscreen

noreply@blogger.com (Lynne Eldridge, MD) — Wed, 30 Apr 2008 15:17:00 +0000

Most health care professionals advice the use of sunscreen for everyone - but unlike people, sunscreens are not all created equal. The Environmental Working Group investigated 1,015 brand name sunscreen products. Of these they found that only 25% were both safe and effective. The issues:

Protection against both UVB and UVA rays:

The FDA does not require that sunscreens offer UVA protection at this time. Unlike UVB rays, which are best known for causing sunburns, UVA rays penetrate deeper into the skin. A lack of studies showing a decrease in the risk of melanoma with sunscreen use, may be in part due to traditional sunscreens lacking UVA protection. Both UVB and UVA rays can cause skin damage and skin cancer. Several products that protect against both UVA and UVB rays are now available.

Ingredients that pose significant safety concerns:

In addition to ingredients that may be irritating or cause allergic reactions, some chemicals in common sunscreen products raise greater concern. Some of these can be absorbed through the skin and mimic estrogen in the body. Some can actually have a skin-damaging effect by forming free radicals when exposed to sunlight.

As we are bombarded by advertising that touts everything from "healthy fast food" to miracle pills that can ease every malady known to man, how does your sunscreen measure up? The Environmental Working Group's "Skin Deep" cosmetic safety base lists 20 sunscreen products that are considered both low hazard and effective here.

The FDA plans on Upgrading Sunscreen Labeling to include information on UVA protection.

Let The Sunshine In - But How Much?

noreply@blogger.com (Lynne Eldridge, MD) — Tue, 29 Apr 2008 16:22:00 +0000

Mom always told us we needed to spend time in the sun, but watching sunscreen commercials makes us wonder if we should venture beyond the front door unless the moon is shining. Do we really need sunshine? And if so, do we dare step outside for 10 minutes without sunscreen?

According to the National Cancer Institute, up to 50% of those living in the US are at high risk for vitamin D deficiency. Vitamin D deficiency has been linked with several cancers as well as conditions such as osteoporosis and cardiovascular disease. Over the past year, studies have been published demonstrating a significant reduction in the incidence of breast cancer, lung cancer, and colorectal cancer in those receiving the equivalent of 1000 IU's of vitamin D daily. For those who have been diagnosed with cancer, increased survival geographically going from north to south has been correlated with sun exposure, and hence vitamin D.

So how do we get vitamin D? Historically, sun exposure has been the main source of vitamin D. While our approach has traditionally been to recommend dietary sources of vitamins alone, this is difficult with vitamin D. Even with vitamin D fortified foods, to get 1000 IU's per day would require drinking 10 glasses of milk! The Canadian Cancer Society has advised that individuals should consider taking a supplement of 1000 IU's of vitamin D daily during the fall and winter months. In the US, the American Society states that some people may require supplements, and this should be discussed with your health care provider.

What do the authors do? Spending 10 to 15 minutes in the sun without sunscreen (sunscreen with an SPF > 8 blocks formation of vitamin D) in average summer attire, can result in the absorption of a whopping 5000 IU's. Of course, this is not recommended for everyone, sun protection (hats, sunscreen) should be used after this time, and you should never burn.

But what if it is cloudy? Many things affect how much vitamin D is produced in our bodies by sunlight, including latitude, complexion, season, and time of day. Clouds reduce absorption by 50% and shade by 60%. People with fair complexions require much less sun exposure to absorb vitamin D than those with darker complexions. At latitudes above 40N (northern California), very little vitamin D is produced during the winter months, and hence the Canadian Cancer Society's recommendation for a supplement.

Have a Sunny Day!

Eat Your Sunscreen! - 10 Superfoods to Lower Skin Cancer Risk

noreply@blogger.com (Lynne Eldridge, MD) — Mon, 28 Apr 2008 17:18:00 +0000

Amidst the spring shower of sunscreen advertisements, we forget there are many ways to lower our risk of developing skin cancer. What we eat can have an impact on whether we will ever have to hear those words, "you have skin cancer!"

It has been shown that those who consume more fruits and vegetables have only half the incidence of skin cancer, whereas those who consume meals high in meat and fat have twice the risk. A few "superfoods" have been shown to pack an extra punch, and make a great addition to a picnic on the beach.

Superfoods for Skin Cancer Prevention:

1. Artichokes - Artichokes are high in silymarin, an antioxidant that has been shown to slow the growth of melanoma cells in mice.

2. Green tea - Epigallocatechin-3-gallate (EGCG), a component of green tea, has been shown to protect the skin of rodents from UV damage. A great treat chilled on the beach!

3. Fish - Omega-3-fatty acids in fish appear to offer protection against non-melanoma skin cancer.

4. Grapes - Proanthocyanidins, present in grapes seeds, have been shown to prevent photocarcinogenesis (cancer caused by sun exposure.)

5. Broccoli sprouts - Sulforaphane, which is high in broccoli and especially broccoli sprouts, was shown to substantially inhibit UV induced skin cancer in mice.

6. Berries - Berries are high in ellagic acid, which appears to have anti-tumor properties in rat skin.

7. Pomegranate juice - An juice extract of pomegranates was shown to protect against UV damage on a molecular level.

8. Carrots - Foods high in beta-carotene appear to have a protective role against skin cancer.

9. Spinach - Spinach is high in lutein/zeaxanthin, which has been shown to reduce UV induced skin cancer in mice when consumed dietarily.

10. Pineapple - Pineapple contains bromelain, a compound shown to decrease cancer in animals.

Practicing common sense, such as using hats and avoiding midday sun exposure are paramount. After all, melanoma, responsible for 75% of skin cancer deaths, had an incidence of only 1 in 1500 people in 1935 when common sense was not exchanged for the blissful feeling that a chemical could protect us from all harm. This incidence of melanoma is now 1 in 84.For further information on cancer prevention, visit Avoiding Cancer One Day At A Time.

A Run And Java To Prevent Skin Cancer

noreply@blogger.com (Lynne Eldridge, MD) — Mon, 28 Apr 2008 03:20:00 +0000

A quick click of the remote in spring, and it isn't long before we hear how we must prevent skin cancer. Prevention, we are told, comes in a multitude of colorful bottles with assorted numbers and can even be applied in colors that dissolve, to make certain every patch of skin is concealed. Could it possibly be that there are "natural" things we can do to lower our risk, in addition to the ubiquitous sunscreen?

Step 1: Take a walk and sip a cup of java!

Researchers demonstrated in the past that mice who spent more time on the treadmill, had a lower risk of skin cancer. Last summer, another dimension was added. Mice that ran on a treadmill plus drank the equivalent of 1 to 2 cups of coffee, had a 400% increase in apoptosis of skin cells that had been damaged by UVB rays. "Apoptosis" means cell suicide, the process by which abnormal cells die rather than progress on to become cancer cells.

Step 2: Tomorrow we will talk about "eating your sunscreen," foods that may protect your skin from the damaging effects of the sun.

Don't Stress Out - Reduce Your Risk of Cancer!

noreply@blogger.com (Lynne Eldridge, MD) — Sat, 26 Apr 2008 14:00:00 +0000

We all know that "stressed out" feeling. Too much to do. Too little time.

And, we know intuitively that stress is not healthy.

But we also know that some people seem to endure endless stressful events in their lives and come out healthy. Others, faced with fewer of these events, but feeling overwhelmed nonetheless, do not fare as well.

The research seems to support our intuition, and the observation that the actual stressful events in our lives are less to blame than our perception of and reaction to them. Credible studies have found an increased risk of developing both breast and cervical cancers in those experiencing more stress. The actual stressful events in these studies did not play a role, rather it was the subjective sensation of stress that was correlated with a risk of cancer. So what can we do to lower our "feelings" of stress?

Play music that relaxes you. (During cold Minnesota stressful winter days, I like to turn up the heat, put on "summer clothes" and dance to Hawaiian music while folding clothes)

Take five minutes alone in a quiet place and slow your breathing

Try visualization. Picture yourself in your favorite place on the planet and "go" there for a few moments

Turn off the news

Learn to delegate

Try yoga

Set limits. Learn how to say no.

My favorite. Make a list of 10 things that are wonderful in your life - such as having toilet paper and clean water, and express gratitude!

We can't change many of the circumstances in our lives, but we do have control of how they make us feel!

Ethnic Foods To Fight Breast Cancer

noreply@blogger.com (Lynne Eldridge, MD) — Fri, 25 Apr 2008 10:00:00 +0000

It is well known that people in different regions of the world have rates of breast cancer that vary considerably. Is this simply because the genetic makeup of certain populations differ? Japanese women have a low rate of breast cancer. If they move to Hawaii, their risk increases, and risk increases further yet if they move to the mainland United States. Clearly genetics alone cannot explain this. So - what does? Studies are increasingly pointing at the role of diet as one explanation.

A recent study looked at the Mexican diet, since Hispanic women have a lower incidence of breast cancer than white non-Hispanic women. It was found that those who consumed a native Mexican diet(right), or a Mediterranean diet(below), had a significantly lower risk of developing breast cancer than those who chose to partake of the traditional western diet.

Last year, a study looked at women who consumed a typical "soy-vegetable" Chinese diet, versus the western diet. Those women who switched over to a western diet had a 60% increased risk of developing breast cancer.

Sadly, countries such as China in the above study, that are adopting our "meat-sweet" western diet, are also beginning to experience our high breast cancer incidence as well.

Action point: Lowering the risk of breast cancer can be fun with this knowledge. Go to your library, bookstore, or online, to find ethnic recipes that look enticing.

Lower Cancer Risk With a "Green" Lawn

noreply@blogger.com (Lynne Eldridge, MD) — Wed, 23 Apr 2008 13:39:00 +0000

Spring has arrived! For those in the north, the sound of lawn mowers and sprinklers strum heavenly chords in our souls after a long winter. We think of health and vitality as we watch our children roll in the grass, and exchange boots for bare feet. Is it possible that such a tranquil vision could be concealing a very real danger?

Sadly, it has been demonstrated in credible studies that children exposed to home and garden pesticides have a significantly elevated risk of developing leukemia and lymphomas. Have you seen those signs posted by commercial lawn companies to keep dogs off the lawn for a period of time? Dogs that live in households that use herbicides containing 2,4-dichlorophenoxyacetic acid (a chemical found in most common weed killers), are twice as likely to die from cancer. In that study, dogs were looked at because it is felt they have more contact with the lawn than humans. As a mother of boys I stand to disagree! Is this really a concern? According to the Environmental Protection Agency, Americans apply 90 million pounds of herbicides and pesticides on their lawns every year.

OK. You understand the risk. You decide to skip the weed killer and let nature rule. But how do you keep up with - or have a lawn that is somewhat presentable living next to - the Jones's that make their lawn a priority? A few tips:

Mow high and often

Add grass seed to thicken the grass and choke out weeds

Consider mulching

If you choose to fertilize, choose "organic" fertilizers from a reputable nursery. Many nurseries now carry alternatives to chemical weed killers as well

If weeds are a concern, trying pulling them, killing them with hot water, replacing lawn with rocks or other forms of landscaping, or simply tolerating them.

Remember, "Weeds are flowers too, once you get to know them." -Eeyore, from A.A.Milne's "Winnie the Pooh"

Safe Summer Grilling - Cancer Prevention Tips

noreply@blogger.com (Lynne Eldridge, MD) — Thu, 17 Apr 2008 02:00:00 +0000

What would a summer picnic be without the grill going? Yet, studies show us that eating grilled foods may raise our risk of developing cancer. As we spring into the summer months of picnics, parties, and that wonderful aroma and taste of grilled food, what can we do to celebrate the taste of the season, without raising our risk of cancer?

Tips for Cancer Prevention:

1. Use Natural Charcoal. Conventional charcoal may contain additives/toxins, including those labeled as carcinogens.

2. Use a fire chimney instead of lighter fluid. Lighter fluid contains petroleum distillates, known carcinogens.

3. Choose rare over well-done with beef (with the exception of hamburger that should always be well-done). Those who choose their cuts of beef rare or medium rare appear to have a lower risk of stomach cancer than those who prefer them well-done.

4. Marinate meats for an hour before cooking. Marinating meats greatly reduces the formation of heterocyclic amines, cancer causing substances produced in grilling meats.

5. Grill vegetables. Grilling vegetables does not result in the formation of the cancer causing substances that can occur with grilling meat, and has the added benefit of adding to the list of "5 to 9."

Eating 5 to 9 servings of fruits and vegetables a day lowers the likelihood that you will have to hear that dreaded phrase, "You Have Cancer." For further information on cancer prevention, visit the web site for Avoid Cancer One Day At A Time.

Ten Tips To Lower Colon Cancer Risk

noreply@blogger.com (Lynne Eldridge, MD) — Sat, 01 Mar 2008 11:54:00 +0000

March Is Colorectal Cancer Awareness Month!

How many of us have lost a loved one to colorectal cancer? Too many - since colon cancer is the second leading cause of cancer deaths in the USA. Thankfully, at least 60 percent of colon cancer deaths can be prevented by timely screening alone. In addition, certain lifestyle practices may lower the risk of developing polyps or cancer in the first place. Here is our top ten.

1. Relish salads - Green leafy veggies are high in folic acid, vitamin B6, and lutein, all of which are associated with a lower risk of developing colorectal cancer. Top them off with a little extra virgin olive oil based dressings and a few berries for an extra punch.

2. Step into the sun - Vitamin D obtained through moderate, sensible sun exposure, has been shown to significantly lower the odds that colon cancer will darken our lives.

3. Give beans about it! - Countries with the highest bean consumption have a lower death rate from colon cancer. As an extra step, saponins, a phytochemical found in beans, might prevent colon cancer cells already present from multiplying.

4. Stand up and dance - Women who exercise more than four hours per week, drop their risk of colorectal cancer 40 percent.

5. Stay away from "cancer sticks" - Studies on smoking and colon cancer are inconsistent, but the risk of rectal cancer is nearly doubled for those who puff.

6. Consider fiber more important than a component of cute clothes - While U.S. studies fail to show a protective effect of fiber on colon cancer, European studies with a higher intake of fiber (35 grams) show promise. A study published in the journal Lancet suggests that people with a low average fiber intake can drop their risk of colon cancer by 40 percent - simply by doubling daily fiber.

7. Go Whole - Whole grains appear to lower the risk - especially the risk of rectal cancer.

8. For us ladies - The calcium we use to keep our bones strong does not appear to lower the risk of colon cancer, at least in postmenopausal women, but it does make it less likely that we will experience regrowth of colon polyps - some of which can lead to cancer.

9. Don't dedicate your life to your job - Certain occupations, such as fire-fighting, raise the risk of colon cancer. Familiarize yourself with workplace risks. More on this later.

10. Be a lean machine - Obesity, especially in men and younger women, raises the risk of developing colorectal cancer. Our January 11th blog entry describes the connection. In the studies "younger women" are considered those aged 50 to 69. Parden me while I retreat to send a love note to that researcher that makes me a babe!

Of course, screening is very important in lowering deaths from colorectal cancer. Current guidelines can be found here. Taking a thorough family history and sharing it with your health care provider is imperative. In some cases, screening should begin much earlier. Many people put off screening - and for a multitude of obvious reasons! See our recent post for insights on turning this dreaded task into a cause for celebration!For further information on cancer prevention, visit our web site, or read "Avoiding Cancer One Day At A Time: Practical Advice for Preventing Cancer."

Colonoscopy Party!

noreply@blogger.com (Lynne Eldridge, MD) — Mon, 25 Feb 2008 12:00:00 +0000

Last week, I was able to check off something that has been on my to-do list for 19 years!

To be entirely truthful, as a more than mildly neurotic type A first-born physician daughter, it has been on my list of things to make my mother do for almost two decades.

She did make a few attempts to follow her doctor's advice to screen for colon cancer over those years. That was her explination for the dozen or so "stool test cards" that I found stashed in the back of her nightstand. She said she knew screening was important enough not to throw them away. Hmmm...

After all, her children co-authored the book "Avoiding Cancer One Day At A Time!" She has heard the statistics. According to the CDC, 60 percent of colon cancer deaths could be prevented through timely screening.

So - why now? She made the appointment before the recent news report that the cancer death rate is decreasing largely due to screening colonoscopies. I could argue that it was the influence of the cute young male physician she is seeing - who looks to be closer in age to her oldest grandson than her daughter (that's me.) It could be that she actually read our book cover to cover, and wants to hang around for her grandsons that adore her. But, knowing my Mom, it was a reason to break up the monotonous winter months with a celebration. Colonoscopy Party!

Sitting in the waiting room amidst other "designated drivers" was an experience unto itself. Unlike a typical doctors office where eyes seldom meet, it was more like a book club experience. Conversation flowed fluently. Watching people leave the waiting room with relief spread across their faces (both the patients and the drivers), reminded me of that solaceful look on kids faces as they throw their caps in the air at high-school graduation. Something was completed, and they could move on and forward to the next step in their lives. As for my mother, she looked like she had just competed her PhD! One small polyp later, she can move on. Ten years if it was a hyperplastic polyp, five if it was an adenomatous (pre-cancerous) polyp, before she has to let the thought of scheduling a colonoscopy clutter her busy mind again.

Perhaps if we recommended colonoscopies be followed with a celebration - like graduation - fewer people would be diagnosed with late-stage cancer, and many would have polyps removed even before they become cancerous. Just think, the greeting card industry could play a role in cancer prevention!

No Fluoride Baby!

noreply@blogger.com (Lynne Eldridge, MD) — Sat, 23 Feb 2008 04:19:00 +0000

I wrote some time ago about the new recommendations regarding fluoride in babies, and was surprised to hear recently (not really surprised), that some health care programs in our country continue to teach about the importance of using fluoridated water for infants. News hits the headlines, but is quickly forgotten.

Last year, the American Dental Association (ADA) announced that infants from birth to a year of age should not be given formula mixed with fluoridated water. They concluded that not only does this fail to protect infants teeth - it can actually damage them, causing a cosmetic problem termed "fluorosis." Worse yet, it appears that infants given fluoridated water are more likely to develop osteosarcoma, a bone cancer most commonly seen in adolescent boys. Though osteosarcoma is rare, it is the second leading cause of childhood cancers following blood related cancers.

Action point: Talk to anyone you know that has an infant on formula and make sure they are aware of this. Formula should be mixed with bottled water, or tap water that has been filtered to remove fluoride. As for the bottle, choose glass or bisphenol A free plastic (available at stores such as Whole Foods.) More about that in another post.

Cancer Proof Your Travels!

noreply@blogger.com (Lynne Eldridge, MD) — Fri, 22 Feb 2008 05:00:00 +0000

When we think of international travel hazards, thoughts drift to Montezuma's revenge and terrorism. Yet, another danger lurks beyond our boundaries. Whereas 10 percent of cancers in the US are caused by infection, that number increases to 25 percent worldwide. Many of these potentially cancer-causing infections can be avoided through knowledge and vigilance. A few to be aware of while enjoying your international adventures:

1. Schistosomiasis - bladder cancer due to the parasitic infection, schistosomiasis, is the leading cause of death in men aged 20 to 44 in Egypt. Schistosomiasis is an infection spread through snails in fresh water. The parasites can penetrate through unbroken skin, and cause chronic inflammation in the bladder that can lead to cancer. Regions where this is found include the Nile River valley in Egypt, Lake Malawi in Africa, as well as certain regions in Southeast Asia, Southern China, Northern South America, the Middle East, and the Caribbean. The parasites are not found in the ocean, and chlorinated water is considered safe.

2. Liver flukes - commonly found in East Asia and especially northeast Thailand, are a significant cause of bile duct cancer. Liver flukes are contracted by eating raw or undercooked freshwater fish that have been contaminated by the parasite. Avoid freshwater sushi when traveling in these regions.

3. H.pylori - infection with the bacteria H.pylori is considered the leading cause of gastric cancer. Gastric cancer has been declining in the US, but remains the fourth most common form of cancer worldwide. It is acquired through person to person contact and ingesting contaminated water and food. When traveling, choose water sources that have been treated with chlorine (and then filtered when possible) or "safe" bottled water. If you develop symptoms of peptic ulcer disease (80-90 percent of cases are due to H.pylori,) consult your health care provider.

4. Hepatitis B - is the leading cause of liver cancer worldwide, responsible for roughly 80 percent of cases. While many cases are sexually transmitted, often the source of transmission is unknown. It is much more contagious than HIV, and can be transmitted even by sharing a toothbrush. Consider immunization, and take precautions around any sources of blood products - even toothbrushes.

5. HIV - is well known for the cancers it can lead to - and its rising incidence, especially in Africa. Before traveling, and travel to Africa in particular, review "universal precautions" on the CDC website listed below.

6. HTLV-1 - Human T cell lymphotrophic virus (HTLV) is a virus rarely found in the US, but infects an estimated 15 to 20 million people worldwide. Of these, roughly 2 to 5 percent will develop adult T cell leukemia/lymphoma. HTLV-1 is most commonly found in Japan, but also occurs in parts of South America, the Caribbean, Papua New Guinea, and central and west Africa. The infection is transmitted through blood, sexually, and from mother to child through breastfeeding.

If you plan to travel internationally, check out the CDC's website to see what infections are endemic in that region and precautions to take. Here at home, as many are keenly aware of with the advent of the HPV vaccine, infections can predispose to cancer as well. Of the 10 percent of cancers in the US caused by infection, a significant number are related to sexually acquired infections. Practice safe sex wherever you are!

Recreation Reduces Breast Cancer Risk

noreply@blogger.com (Lynne Eldridge, MD) — Wed, 20 Feb 2008 12:02:00 +0000

A study due to be published in the March issue of "Epidemiology," entices us to find entertaining ways to exercise to reduce our risk of developing breast cancer. The researchers, noting that epidemiological studies have shown breast cancer risk to be reduced 30 to 40 percent in highly physically active women, evaluated the effect of moderate to vigorous recreational activity on breast cancer in Polish women.

The results: Total adult lifetime activity decreased the risk of breast cancer.

The breakdown was as follows:

- Moderate to vigorous recreational activity 26 % reduction
- Outdoor activites 19 % reduction
- Heavy physical work 40 % reduction
- Combined high intensity exercise 25 % reduction

And, according to the study, it is never too late to begin. Women who increased their recreational activity in their 50's, had a significantly lower risk of developing breast cancer.

Action point: Find a recreational activity you enjoy, preferably one you can share with your partner, friends, or children. A few ideas:

- Tennis
- Hiking (my favorite, many hiking trails worldwide makes this a lasting hobby)
- Rock climbing
- Kayaking/canoeing
- Dancing
- Gardening
- Skiing
- Any game that can be played with children

The best exercise is something you enjoy, even crave, and return to again and again for fun and enjoyment.Reference: Peplonski, B. et al. "Adult Lifetime Physical Activity and Breast Cancer." 2008. Mar; 19(2):226-236.

Stress May Raise Cervical Cancer Risk: Should We Worry?

noreply@blogger.com (Lynne Eldridge, MD) — Tue, 19 Feb 2008 03:08:00 +0000

In a society where we are all "stressed out," we can add another entry to our worry list.

Stress may increase the risk of developing cervical cancer. A study published this month in "Annals of Behavioral Medicine," found that women who felt more stressed had a poorer immune response to HPV, the virus that causes the inflammation that can lead to cervical cancer. Before losing sleep for a night, let's look at the study. There is something we can do!"

But...but...but, my life is stressful!!!"

It is true that many stressors are beyond our control. Job changes happen. Relationships change. Illness occurs. Financial pressures abound in the current market. But, this study did not find a difference in the objective levels of stress in a woman's life. The difference was in how stressed women "felt!"A study some time back in Sweden showed a similiar scenario with breast cancer. There was no difference in breast cancer based on objective measures of stress in women's lives, but those who "felt" more stressed had an increased incidence.

Even if we can't change our life situations, we can try to find them less stressful. Here are a few tips:

- Try to arrive everywhere you go ten minutes early

- Set limits, don't be afraid to say no

- Play music that relaxes you and brings back pleasant memories

- Try yoga

- Go to sleep. Issues that seem insurmountable at night can often be solved in the light of day

- Declutter your life

- Try visualization. Imagine yourself beyond the current stressful event, in your ideal situation

Life is stressful enough, without worrying that it will raise our risk of cancer! For further information on cancer prevention, visit our web site, or read "Avoiding Cancer One Day At A Time".

A New Cancer Risk From Cell Phones?

noreply@blogger.com (Lynne Eldridge, MD) — Mon, 18 Feb 2008 01:41:00 +0000

We have all heard the debate about cell phones and brain tumors, but could cell phone use increase the risk of another type of cancer? A study published this week in the "American Journal of Epidemiology" suggests this is the case.

This study, led by researchers in Israel, found that heavy cell phone use increased the risk of benign (non-cancerous) and malignant (cancerous) salivary gland tumors, in particular of the parotid gland. The parotid gland is a salivary gland located in front of the ear, and is best known as the gland that swells - causing the characteristic appearance of an individual with mumps.

The study, unlike many other epidemiological studies, compared "heavy use" of cell phones rather than "ever use" of cell phones to come to their conclusions. Those who were in the highest category of cell phone use, based on number of calls and total call time, had a 58 percent increased risk of developing parotid gland tumors on the side of the head where they held the phone. There was no increased risk of tumor development on the side of the head where they did not hold the phone.

With 90 percent of individuals in Western countries using cell phones, what should we do with this information?

Sadetzski, the lead researcher in this study, suggests that parents be vigilant about their children's use of cell phones, limiting the number of calls and time spent on the phone. Many European countries have already taken actions to protect children, and recommend children use cell phones only for necessary calls to parents. This is not based on documented studies at this time, but on the theoretical risk to developing brains. The latency period (time between exposure and cancer) for many cancers is long. If tobacco came out when cell phones did, we may not see an increase in cancer...

In the USA, we may want to consider the European approach to cell phone use in children. After all, even if cell phones are given a green light in 30 years, many of our children are replacing time spent exercising and doing homework with time on their cell phones. With childhood obesity skyrocketing and test scores declining, we would be wise to take note.

Could New Acne Treatment Cause Cancer?

noreply@blogger.com (Lynne Eldridge, MD) — Thu, 14 Feb 2008 01:42:00 +0000

My mother always says "look beneath the skin." Great advice from a child psychologist turned stay-at-home mom for evaluating relationships, but keen advice for evaluating well-respected journalism as well.

Browsing Yahoo Health, an article from Reuters caught my eye. "Drug Combo treats severe acne in women: study." Knowing the emotional turmoil those tiny spots can inflict on the composure of otherwise self-confident women, I rapidly clicked, and even more quickly became alarmed.

This study, published in the January 2008 Journal of the American Academy of Dermatology, cites the combination of the birth control pill Yasmin(r) and spironolactone (a diuretic) as a safe and effective treatment for acne. In this study, recipients had an 85 percent chance of either being free from their acne or having excellent improvement. And complications were low. There was no significant weight gain or menstrual cycle irregularites and no problems with elevated potassium levels.

But, what about the long run? Most of these women are young!

We know that oral contraceptives, such as Yasmin, are associated with a small increase in the risk of pre-menopausal breast cancer. How small? In the worst case scenario in the studies, using these for four years before the birth of a first child conferred a relative risk of 1.4. Simply said, if we consider the current risk of breast cancer to be one in seven women (some may argue one in eight or nine), this risk would now be one in five. This risk can often be justified. Going through pregnancy and delivery could definitely be considered riskier. But acne?

And then add in spironolactone. This is a great drug in certain conditions. It can help with fluid retention in those with heart failure and cirrhosis, and be a life saver for those with a condition called primary aldosteronism. Yet, as with many potentially life-saving treatments, that treatment can come at a cost. Spironolactone is listed in California's Proposition 65 under chemicals associated with a risk of cancer.

Shocking - but not really. Looking back at the treatment of acne over the years, we laugh at our ignorance as we raised cancer risk while treating a cosmetic nuisance. First it was X-rays, now known to increase the risk of thyroid cancer. Then it was sun (UV ) exposure. Will we look back in thirty years and question why we considered a combination of a known and a probable carcinogen an acceptable treatment for something only skin deep?

Myself - I plan on listening to my mother's advice. "Look beneath the skin." With the alarming incidence of breast cancer in our country, and one in three women expected to develop some form of cancer in addition to skin cancer, I think I'll opt for safer alternatives.

And for my kids it serves as an internet lesson. Unlike the TV ads as of late portraying the wonderful advantages of a multitude of meds, a laundry list of potential problems did not follow this article, nor was I able to find a direct way to contact anyone to discuss our concerns.

Breast Cancer Prevention: What to Eat, What Not To Eat

noreply@blogger.com (Lynne Eldridge, MD) — Tue, 05 Feb 2008 11:42:00 +0000

Our book Avoiding Cancer One Day At A Time was conceived as we tried to share what we know about cancer prevention with those we love.Do you know someone who has had breast cancer, or are you a breast cancer survivor yourself? Every time I hear of another family member, friend, acquaintance, or friend-of-a-friend who has been diagnosed with breast cancer, my heart aches to know the causes. Even with my loved ones who are cancer free, and thriving as breast cancer survivors - it pains me to think of what they went through - just to be here.

Many factors contribute to the development of breast cancer. The environment, genetics, lifestyle, and diet all play a role. Thankfully, diet is something we can do a lot about - if we know the foods that may increase or decrease risk. Much remains to be studied, but consuming - or avoiding - the following foods, may alter your risk of developing breast cancer based on credible studies.

The "Good" Foods

Apples: Apples, especially the skin, have been shown to offer protection against breast cancer, although the amount in the study was equivalent to five apples per day. An apple a day (we recommend organic since apples are one of the foods with the highest pesticide residue), may keep the oncologist away. Apple cider is preferable to apple juice since it includes the skin.

Green tea: Studies have shown a protective effect against many cancers, including breast cancer, with the consumption of green tea. Interestingly, green tea extract is being evaluated in clinical trials for those with cancer at several major cancer centers.

Seaweed/kelp: Seaweed appears to be protective against breast cancer, and is considered one of the reasons for the lower incidence of breast cancer in Japan. Miso soup is a great way to get seaweed in your diet, is easy to prepare, and even this 100 percent Swedish author by heritage, craves this Asian staple.

Pomegranates: Pomegranates appear to be protective against breast cancer, and are delicious when purchased fresh. They can also keep kids busy for a long time - giving mom the opportunity for a few healthy deep breaths.

Cruciferous vegetables: Cruciferous veggies appear to offer protection against breast cancer. Studies show this effect with a fairly high consumption - e.g. a head of cauliflower or broccoli a day. Look for other vegetables in the cruciferous category for variety. Examples include: cabbage, brussel sprouts, Chinese cabbage, bok choy, mustard greens, kale, collard greens, kohlrabi, turnips, rutabaga, arugula, wasabi, radishes, and horseradish.

The "Bad" Foods

Acrylamide: Recently, a new study reported an increased risk of breast cancer in those with higher blood levels of acrylamide. Acrylamide is a chemical formed when starchy foods are heated. The most common sources are potato products (esp. fries and chips) and bread products. Avoid overcooked potatoes and bread products. A listing of the acrylamide content of various foods is available on the Internet.

Red meat: Women who eat red meat seven days per week were shown to have an elevated risk of breast cancer. Processed meats should also be minimized.Grapefruit: Does anyone remember the grapefruit diet? I do. In high school my mother and I would do the two week grapefruit diet to stay trim. We thought we were healthy! Not so. Women who consumed a quarter of a grapefruit daily, were 30 percent more likely to develop breast cancer in a recent study. Grapefruit interferes with an enzyme in the liver, resulting in higher serum levels of estrogen.

Special Circumstances

Flax: Flax may be protective against breast cancer, but can interfere with chemotherapy. If you have breast cancer, consult your oncologist about the use of flax.

The Soy Issue: Soy appears to lower the risk of premenopausal breast cancer slightly, but the benefit seems to be limited to those who consume during adolescence, when breast tissue is differentiating. On the reverse side of the equation, breast cancer cells grown in a dish, grow more rapidly when fed soy. Use soy in moderation after adolescence and avoid soy supplements.

The Secret History Of The War On Cancer - On CSPAN

noreply@blogger.com (Lynne Eldridge, MD) — Sat, 02 Feb 2008 04:23:00 +0000

Tune in to C-SPAN 2 this weekend!

Many of our blog entries and a large section of our book speak of the environmental risks for cancer -and what we can do to lower those risks. Not a small concern, since roughly 90 percent of cancers are caused by the environment rather than genetics. This - and the fact that one in two men and one-third of women will develop cancer in their lifetime.

Thankfully, there are people like Dr. Devra Davis, Director Of Environmental Oncology at The University of Pittsburgh, who have exposed the errors - at multiple levels - in our war against cancer. Through her work, and the foundation she has begun, we have new hope, that fewer of us will have to hear those awful words: "you have cancer."

Tune in to C-SPAN 2 this weekend on Saturday evening or Sunday morning!Devra will be discussing her new book "The Secret History of the War on Cancer" on Book TV on C-SPAN 2 this weekend on Saturday at 10 PM (EST) and on Sunday at 6 AM (EST).

Further information on the work Dr. Davis is doing, and general information on the environment and cancer risk is available online. Unlike the funding to study chemotherapy drugs, funding to evaluate the role of the environment in causing cancer is lacking. The Center for Environmental Oncology has a donation program where you can contribue to this important cause. You can see our friend Rich Pagen, who took this to another level this summer, paddling for the cause.

Devra Davis has been called the Rachel Carson of this era. Speaking with her today, she was very humble in her response. Yet, the impact of her work could make the impact of pesticide awareness from that era pale in comparison.

Green Means GO - 10 (Green) Tips To Lower Cancer Risk

noreply@blogger.com (Lynne Eldridge, MD) — Fri, 01 Feb 2008 04:02:00 +0000

Tips from Avoiding Cancer One Day At A Time: Practical Advice for Preventing Cancer.

The green movement - once a diminutive entity moved along by long-haired hippies in tie-dyed shirts - is now an international subject of discussion to those clad in Birkenstocks and Armani suits alike. In fear of what lies beyond our Anthropecene Era, a new language has emerged. We talk about the "price of carbon" and "dinosaur wine." Our shopping options include an ever expanding array of "eco-friendly" products. And, reading food labels has transcended to a new dimension altogether. Once reserved for the "granola crowd," and a descriptive term for a branch of chemistry,"organic" is IN.

There are those who debate global warming and the necessity of change. Heated dialogue about the significance of topics such as fuel and sustainable agriculture will perist. Regardless of whether our efforts - or lack therof are contributing to global warming and destroying our planet, the green movement has brought to the forefront many tips that may lower our risk of cancer. With one in two men and one-third of women expected to develop cancer in their lifetimes, it is time we listen!

Ten "Green Tips" To Lower Cancer Risk:

1. Leave the cars keys at home - when possible.

Not only do fossil fuels harm our environment, they can harm our health. Men who work in filling stations have an elevated risk of breast cancer. Women attendants were not studied. And, burning that fossil fuel lowers our need to get out and walk - something that lowers the risk of cancer.

2. Go organic - at least with some foods.

Many conventionally used pesticides have been shown to cause cancer in animals. Since these linger long after they do their dirty deed, there are environmental implications as well. Thanks to Rachel Carson, the Eagles are returning! But, shopping organic on a budget can leave holeless pockets empty. By purchasing the following foods organically grown, you can eliminate roughly 80 percent of the pesticides on your plate: meat, dairy, strawberries, apples, tomatoes, potatoes, leafy greens, coffee, peaches and nectarines, grapes, celery, and bell peppers.

3. Look for "eco-friendly" furnishings.

The Environmental Protection Agency (EPA) ranks indoor air 4th in environmental causes of cancer. Some sources, such as fossil fuel, are difficult to avoid. Other sources, such as chemicals in upholstery, pressed wood products, and carpeting, deserve scrutiny. For "eco-friendly" options, check out The Green Building Resource Guide.

4. Turn off the lights.

Not only does turning off the lights help our environment, it may lower our risk of developing cancer as well. Melatonin, a hormone manufactured by the brain in total darkness, appears to lower the risk of breast and prostate cancers.

5. Bring your lunch to work.

Rather than further burdening landfills choked with containers from lunch purchased on the run, bring your lunch to work in a reusable container. Making choices at home raises the likelihood of adding nutritious fruits and vegetables, and choosing non-processed lunch meats, choices that can reduce your likelihood of developing cancer.

6. Choose green (or at least non-bleached) paper products.

Chlorine treated paper products result in the production of dioxins (a carcinogen) in the atmosphere when burned. On an individual basis, this can be concerning as well. According to the EPA, using bleached coffee filters can result in a lifetime dioxin level that exceeds acceptable levels.

7. Choose green personal care products.

Cosmetics can contain petroleum products and plastics that use fossil fuels and accumulate in the environment. Do you want them on your skin? To make wise choices, visit the web site of The Campaign For Safe Cosmetics.

8. Skip the drycleaner.

Wash your clothes at home, or choose an establishment that uses "wet-cleaning" or liquid CO2 cleaning. Most conventional drycleaners use perchloroethylene (perc), a chemical that has been noted to accumulate in the environment. Perc also poses a significant cancer risk for those who work in the drycleaning business. Whether or not this poses a significant cancer threat to those who have their clothes cleaned, do we really want to put someone at risk of cancer - just to wash our clothes?

9. Avoid green wood.

Thus far we have written about the virtues of green. A green tint in wood suggests it is arsenic treated, and in fact "CCA" treated wood was used for roughly 90 percent of outdoor wooden play structures until it was banned in 2003. The environmental working group has suggested that as many as one in 500 children will develop cancer from their time playing on CCA treated wood structures during their lifetime. If you have one of these structures, seal it yearly, and practice good hand washing. Read the Environmental Working Group web site for more information.

10. Choose green greens!

Golf courses are known for their beautiful greens, but those who manage them have an elevated risk of non-Hodgkins lymphoma, brain, prostate, and lung cancers. Take care of those who preserve your passion. Request your golf course use organic products - especially weed products. If they don't comply, at least remove your shoes when you return home to keep them away from your family, even dogs that live in a household where chemical weed killers are used are twice as likely to die from cancer. How do you know if a product is "green?"

Colon Cancer Prevention: Double Benefit Of One Step

noreply@blogger.com (Lynne Eldridge, MD) — Wed, 23 Jan 2008 12:05:00 +0000

Those who have listened to me speak, or read our book Avoiding Cancer One Day At A Time know my favorite step for lowering cancer risk. "Take a walk in the sun!"

With regards to colon cancer prevention, that walk earned double points this year.Walking: A large study published in the International Journal of Cancer last month showed that women who walk as little as one hour per week have a lower incidence of colon cancer. Women who walked between 1 and 2 hours per week had a 31 percent reduction in colon cancer. This increased to a 44 percent lower incidence in those that exercised moderately 4 hours per week. In the Sun (Vitamin D): A separate study concluded that individuals who raise their blood levels of vitamin D to 46ng/ml - a level achieved by receiving 2000 IU's of vitamin D daily - could cut their risk of colon cancer by two-thirds.

Practical tips are (i) wear a pedometer. Figure out the average number of steps you take in an hour of walking, multiply it by four, and try to reach at least that number weekly. Another recent study demonstrated that those who wore pedometers, increased the distance they walked by one to two miles per day, and lost weight - even without a change in diet.

(ii) Apply sunscreen after being in the sun for ten minutes. Ten to fifteen minutes in the sun can result in the absorption of a whopping 2000-5000 IU's of vitamin D. Sunscreen can block the absorption of vitamin D (for those at high risk of skin cancer, see below). - For those who can't tolerate the sun or choose to walk indoors, ask your health care provider whether a vitamin D supplement should be considered. Based on the reduction in colon, as well as breast and lung cancers, Canada now recommends vitamin D supplementation for most citizens. While we prefer dietary measures, this is difficult with vitamin D. To get 2000 IU's from food could mean 20 glasses of milk and a little salmon and herring - not something we recommend daily!

(iii) Make walking fun. Turn on lively music as you clean your home. Plan activities and vacations that require walking - to see what only those who walk can see. Park as far away as possible at the mall and grocery store, and give thanks, that as you put on the miles, you are not contributing to global warming driving up and down aisles for the perfect spot!

Ten Foods To Avoid To Prevent Cancer

noreply@blogger.com (Lynne Eldridge, MD) — Sun, 20 Jan 2008 14:05:00 +0000

With recent studies linking the consumption of low-fat milk with prostate cancer, and consumption of red meat with colon and lung cancers, we are reminded that there are some foods we may want to minimize in our diet. In general, with the exception of a poisonous fish in Asia considered a delicacy, and certain mushrooms, few foods are dangerous on their own. A healthy diet consisting of a wide variety of fruits and vegetables, and moderation with meat/dairy/fast food and high-cal snacks should be the central theme.

For those who wish to fine tune their diet and lower their risk further, minimize these:

1. Foods containing acrylamide, such as french fries and potato chips. Acrylamide, a chemical formed when starchy foods are heated, was labeled a probable human carcinogen in 2005. A list of acrylamide content in various foods can be found at www.oehha.ca.gov/prop65/acrylamideintakefdaappendix.pdf.

2. Grapefruit. It saddens us to list a forbidden fruit, but those trying to lower their risk of breast cancer should moderate their grapefruit consumption. Women who consume a quarter of a grapefruit on a daily basis, are 30 percent more likely to develop breast cancer. Grapefruit interferes with an enzyme in the liver - allowing the gut to reabsorb more of the body's natural estrogen - resulting in a higher level of estrogen in the body.

3. Trans fats. As New York City set out to eliminate trans fats from restaurants, and food labels began listing trans fats in 2006, the world became aware that saturated fats alone were not the problem. For those who think New York went to the extreme, check out a study that has me reading food labels. The amount of trans fats in a woman's buttocks is directly proportional to her risk for breast cancer. A word of caution. As products begin eliminating trans fats, what are they substituting? In general, products containing, or that contained, trans fats, should be minimized.

4. Soda. While soda alone has not been linked with cancer, it has been shown to increase the risk of obesity - both the regular variety and diet. Currently obesity is responsible for 20 percent of cancer deaths in women and 14 percent in men. If that doesn't make that 12-pack less appealing, remember soda is often substituted for other drinks such as water, which lowers the risk of certain cancers, and the cancer-fighting phytochemicals in vegetable and fruit juices.

5. Processed meats. Regular consumption of processed meats is associated with cancers of the lung, colon, liver, and esophagus. Esophageal cancer is the most rapidly growing cancer in the USA.

6. Fried foods. And not simply because of the calories and acrylamide. When oil is heated and reheated, more free radicals are produced. Most importantly, avoid fried foods when eating out - where restaurants frequently reheat the oil they use, or "top-off" the old oil rather than starting fresh.

7. Foods containing the preservatives BHT, BHA. BHT has been shown to cause cancer in animals. BHA is considered a possible human carcinogen.

8. Orange peel. That is - orange peel from non-organic Florida oranges. The food dye citrus red #2, known to cause cancer in animals, is used to make the greenish appearance of Florida oranges resemble the deep orange of California oranges.

9. Refined sugar. A high intake of refined sugar, also known as a high glycemic load, is associated with cancer of the breast and upper digestive tract.

10. Smoked and pickled foods. Both smoked and pickled foods are associated with cancers of the digestive tract.
