Mesothelioma — malignant (thicket) a tumor growing from мезотелиальной of a fabric, with sites from cages and аденоматозной fabrics. As a rule, a tumor find out in a pleura and a peritoneum, is more rare — in and joints. Grows as the thick layer covering an internal, and consists from cages and a fibrous fabric.

Risk factors: long contact to asbestos, smoking.
Classification • the Mesothelioma good-quality — a mesothelioma in the form of knot on a leg or the wide basis • the Mesothelioma malignant (a cancer) is characterized growth and propensity to early
Pleura mesothelioma (МКБ-10. C45.0 a pleura Mesothelioma)

• the Clinical picture: a short wind (connected with pleurisy), pains in a thorax (owing to tumor germination in), cough and a blood spitting, decrease in weight of a body. Diagnostics: survey thorax bodies; a pleural puncture, evacuation of an exudate and its cytologic research; and a tumor biopsy.

Asbestos mesothelioma complaint filed at Holyoke High School

noreply@blogger.com (Maksim Reshetnikov) — Tue, 29 Jun 2010 10:51:00 +0000

The federal Occupational Safety and Health Administration is investigating an anonymous complaint that workers had uncovered high levels of asbestos while working on a renovation project at Holyoke High School in Holyoke, Massachusetts.
The project manager on site, however, has assured that testing was completed. He noted that regulations have been followed throughout the year, and that both the air and dust were tested.
School Superintendent Eduardo B. Carballo noted, “These are serious allegations...but I am assured by the manager of the project that they are going to check it out,” reports MassLive.com.
Additional tests have been planned in light of the complaint, and school officials have assured parents that students are safe.
If high levels of asbestos were released in the air, however, it would put those exposed at risk for contracting diseases such as asbestosis, lung cancer and mesothelioma. Mesothelioma is the most rare and aggressive form of diseases to arise from asbestos exposure--and affects the chest, heart and abdominal cavities.
Mesothelioma doctors struggle to diagnose patients early on with the disease, and find difficulty in treating patients. Palliative treatment options, such as chemo, may extend the life of a patient, but there is currently no known mesothelioma cure.
Company owner of Samsyd Window and Door Co., John Samysd, noted that one of his employees asked for caulk surrounding the high school’s windows to be tested for asbestos. Three of the four samples tests displayed high levels of asbestos.
Project designer for Forbes & Wheeler, Stephen W. Niec, said his firm had regularly tested the air and dust at the high school. However, Niec noted that, in light of the complaint, he would be returning to the high school to complete more tests.

Asbestos abatement to occur at Maryland schools prior to large renovation project

noreply@blogger.com (Maksim Reshetnikov) — Tue, 29 Jun 2010 10:50:00 +0000

Many Washington County Public Schools will undergo improvements this summer, and it will reportedly cost more than $10.9 million for the list of Maryland schools to improve several sections of their buildings, according to the Herald Mail.
The majority of projects are expected to conclude this summer. However, two heating, ventilation and air conditioning projects, at Boonsboro Middle School and Emma K. Doub School for Integrate Arts & Technology, have been postponed until 2011.
Work at Funkstown School for Early Childhood Education will carry into the fall.
Asbestos abatement is set to occur at E. Russell Hicks Middle School, Emma K. Doub School for Integrated Arts & Technology, Smithsburg High School, Western Heights Middle School, Williamsport High School and Winter Street Elementary School.
The asbestos removal must occur before any further improvements or renovations may begin. When asbestos is disturbed, without first being properly removed, toxic particles are released into the air. When the asbestos particles are inhaled, those exposed are put at serious risk for contracting asbestosis, lung cancer, or even worse, mesothelioma.
Mesothelioma is a rare and aggressive disease which affects nearly 3,000 Americans each year.
Symptoms of the disease lie dormant for several decades, and because of this, mesothelioma doctors struggle to diagnose patients with the disease early on. There is no mesothelioma cure.
Director of maintenance and operations, Mark J. Mills, noted that the school system is sharing the total projects’ cost. However, a few projects, such as window replacements, have other funding sources.

HOW DID I GET IT?

noreply@blogger.com (Maksim Reshetnikov) — Sun, 16 May 2010 13:29:00 +0000

The only known cause of mesothelioma is exposure to asbestos. Mesothelioma results from breathing microscopic asbestos fibers into the lungs. When breathed into the lungs, asbestos tears the lung tissue. Because asbestos was very inexpensive, asbestos was used as a filler in many different products. For example, asbestos was used in cements, drywall muds, brake and clutch linings, roof shingles, gaskets, flooring products, paints, textiles and insulation. The fibers cause the lungs to form scar tissue again and again (asbestosis) or can cause lung cancer. If asbestos fibers damage mesothelial tissue, it may lead to mesothelioma.

Smoking does not cause mesothelioma. However, studies show that someone who was a smoker and was exposed to asbestos, is more likely to suffer from mesothelioma than a non-smoker.

Generally, it takes 20 to 50 years from the time of asbestos exposure until symptoms appear or mesothelioma is diagnosed. This time is called the "latency" period.

Mesothelioma is a serious disease. Half of the patients diagnosed at an early stage and treated aggressively live two years from the date of the diagnosis. One in five are still alive five years after diagnosis. Some patients live more than five years after diagnosis, but generally only if they have been diagnosed at an early date.

WHAT IS MESOTHELIOMA?

noreply@blogger.com (Maksim Reshetnikov) — Sun, 16 May 2010 13:28:00 +0000

Mesothelioma is a cancer of the mesothelium; the protective sac that covers and protects most internal organs of the body. The mesothelium has two layers, one, which covers the organ, and a second, which forms a sac around it. The mesothelium has different names depending on the location in the body. The pleura is the name for the mesothelial tissue surrounding the lungs and lining the chest cavity. The peritoneum covers most of the organs in the abdominal cavity, while the pericardium covers and protects the heart.

The mesothelium produces a lubricating fluid that allows organs within it to move and glide easily. The fluid allows the lungs to breathe and the heart to expand and contract without creating any type of internal friction.

Like other forms of cancer, mesothelioma occurs when cells become abnormal and divide or grow out of control. When someone has mesothelioma, the helpful lubricating fluid described above may be over-produced. This excess fluid encases the organs with a thick layer of tumor tissue, described as a rind type of layer. In advanced cases of mesothelioma, cells metastasize, or grow and invade other organs and spread to other areas of the body.

The majority of individuals suffering from mesothelioma have cancer in the lining of the lung. Sometimes, mesothelioma occurs in the lining of the abdominal cavity (peritoneal mesothelioma) or in the lining of the heart (pericardial mesothelioma).

The symptoms of mesothelioma are common to a number of illnesses which means that mesothelioma is difficult to diagnose. Unique types of treatment for mesothelioma are still being investigated through clinical trials and research, but as a general rule, mesothelioma does not respond well to most treatments that are currently being offered.

Mesothelioma is caused by breathing or ingesting asbestos fibers. The coarse fibers cause scarring of the mesothelial tissue which can cause asbestosis or pleural plaques. Unfortunately, the scarring can also lead to cancer known as mesothelioma.

It often takes 20 to 50 years after exposure to asbestos before the symptoms of mesothelioma develop. This period of time is referred to as a latency period. Because of the latency period, the disease commonly affects men and women that are at least 50 years of age and that worked with asbestos between 20 and 50 years ago. Many workers working 20 to 50 years ago did not use any type of protection in the workplace while they were exposed to the dust or fibers from asbestos. At the same time, however, many of the companies employing the workers had full knowledge that asbestos was dangerous and that exposure to asbestos would harm the health of many of the workers. Insulators, plasterers, electricians, pipefitters, mechanics, ironworkers, ship builders, ship workers, brick layers, carpenters, and other tradesmen are just a few examples of workers that were likely to work with asbestos on a day-to-day basis. Also at risk are the families of these workers, as the asbestos fibers may be brought into the home from the clothes, skin, or hair of the worker.

Unfortunately, millions of people have been exposed to asbestos over the years. Only now are we able to see the disastrous effects of asbestos exposure in the workplace.

As with other cancers, a speedy diagnosis is important to effective treatment of mesothelioma. If you believe that you may have mesothelioma and that you worked with asbestos in the past, you may wish to inform your doctor of this fact.

About Mesothelioma

noreply@blogger.com (Maksim Reshetnikov) — Tue, 30 Mar 2010 20:58:00 +0000

About Mesothelioma

Mesothelioma is a rare form of cancer that develops in the mesothelial cells. These cells are tissue that surround or line the lungs, heart, and stomach. The mesothelial cells protect these organs by producing a lubricating fluid that allows these organs to move smoothly.

Malignant mesotheliomas arise from the cells that line the surface of the pleura or the peritoneum. Eighty percent of these tumors are pleural in origin. Malignant mesotheliomas are rare, with an incidence of one to three cases per 1 million persons per year in the general population. Approximately 2000 new cases are diagnosed each year.

The relationship between asbestos exposure and malignant mesothelioma was established in 1960. The latency period between exposure and tumor development has usually been 30 years or more.

The incidence of malignant mesothelioma has been highest in persons with heavy occupational exposure to asbestos, such as shipyard workers. However, malignant mesothelioma can occur in the absence of any known asbestos exposure. No history of such exposure has been noted in about one-third of cases, and the etiology of these cases is usually unknown. Some cases of mesothelioma have been diagnosed in family members of asbestos workers and people who reside near asbestos mines. Cigarette smoking is not considered a risk factor for malignant mesothelioma.

The patient with malignant mesothelioma of the pleura may have symptoms of dyspnea (shortness of breath)and pleuritic chest pain (pain with breathing), with malaise and weight loss. A large pleural effusion is often seen on the radiograph. This effusion which is a collection of fluid between the lungs and the chest is frequently bloody, and the hyaluronic acid level may be elevated. Associated parenchymal fibrosis (asbestosis) is rare in pleural mesothelioma but appears to be more common in peritoneal mesothelioma.

Malignant mesothelioma can be very difficult to diagnose, although medical advances have made it somewhat easier. A CAT scan or an MRI scan may show the cancer; If the cancer is in the chest, a surgeon can make a small incision between two ribs and insert a tiny instrument with a light and a camera inside, and take samples with this instrument. If the cancer is in the abdomen, a similar procedure, called a peritoneoscopy can be performed. Actual open biopsy is only necessary if there is no other way to obtain tissue,

There is no 100% effective treatment for malignant mesothelioma. Complete surgical resection is not possible in most cases. In many cases, part of the pleura and part of the tumor can be removed, surgery which decreases symptoms. The tumor encases the lung in a bulky, lobulated mass that invades the fissures and, eventually, the diaphragm and the chest wall. Average survival is one to two years. Except in rare cases, chemotherapy and radiation therapy have not been useful. Despite these facts however, there have been patients who have lived longer because of emerging treatments, and earlier diagnosis.

Type of Pleural Effusion Important for Mesothelioma Diagnosis

noreply@blogger.com (Maksim Reshetnikov) — Tue, 30 Mar 2010 20:54:00 +0000

by Nancy Meredith
Pleural effusions are found in 95% of all pleural mesothelioma cases. When a patient presents to a doctor with pleural effusion, however, there are many other diseases which could cause the fluid buildup. There are multiple medical tests that should be conducted by the physician to determine the cause, but when exudative pleural effusion is identifed, the type associated with lung disease, a patient history to assess the possibility of asbestos exposure is important.

Pleural mesothelioma is a form of lung cancer that is almost always caused by asbestos exposure and is most commonly found in the outer lining of the lungs called the mesothelium. Due to the long latency period most cases of mesothelioma are diagnosed 30 years or more after exposure.

A pleural effusion is an accumulation of fluid between the layers of tissue that line the lungs and chest cavity. In healthy adults the body produces pleural fluid in small amounts to lubricate the surfaces of the pleura. This fluid is normally removed by lymphatics in the parietal pleura, which have the capacity to absorb 20 times more fluid than is normally formed. When this capacity is overwhelmed, a pleural effusion develops.

Transudative Effusions vs Exudative Effusions
Determining the cause and type of the pleural effusion is critical in treating the underlying disease as well as determining the appropriate method to clear the fluid from the chest cavity. A lung surrounded by excess fluid for too long may collapse.

There are two types of effusions: transudative effusions and exudative effusions.

Due to elevated pressure or low protein content in the blood vessels, fluid leaks into the pleural space causing transudative effusions. Systemic factors that alter the balance of the formation and absorption of pleural fluid, such as pulmonary embolism and cirrhosis, are the root of transudative effusions. Congestive heart failure is the most common cause of transudative effusions. Other causes include constrictive pericarditis and peritoneal dialysis.

Leaky blood vessels caused by inflammation involving irritation and swelling of the pleura and alterations in local factors that influence the formation and absorption of pleural fluid result in exudative effusions. Exudative pleural effusions are associated with asbestos-related diseases such as mesothelioma and asbestosis. The effusions are often caused by other lung diseases, including lung cancer, lung infections such as tuberculosis and pneumonia, and drug reactions.

Light's Criteria
According to The Merck Manuals the path to take in diagnosing the disease causing pleural effusion includes using Light's Criteria. This set of criteria was developed by Dr. Richard Light, Pulmonary Disease Physician and Professor of Medicine at The Vanderbilt Clinic, Nashville, TN, and Director of Pulmonary Disease Program, St Thomas Hospital, Nashville.

The two effusions are differentiated by comparing chemistries in the pleural fluid to those in the blood. Light's Criteria looks at the ratio of pleural fluid protein to serum protein, the ratio of pleural fluid LDH to serum LDH, and whether the pleural fluid LDH is more than two-thirds the normal upper limit for serum. If the criteria are met then exudative effusion is assumed and additional evaluation is needed to determine the cause of the excess fluid.

Personal History
Dr. Light agrees with his colleague Gary Lee, Consultant Physician & Senior Lecturer, Osler Chest Unit, Churchill Hospital, Oxford, UK when he says that it is important to go beyond Light's Criteria and get a detailed history of the patient so the treating physician knows what to do with the exudative identification.

Since X-rays, CT scans and potentially ultrasound have all been performed leading up to confirming that the patient has pleural effusion, and further tests confirm that the effusion is exudative in nature, if the patient's history reveals exposure to asbestos the doctor may be able to move to tests to eliminate or confirm an asbestos-related disease by checking mesothelial levels.

Injury (inflammation) to the mesothelium triggers events leading to the migration of mesothelial cells from the edge of the lesion towards the wound center, causing an increase in levels. Neoplastic transformation (conversion of a tissue with a normal growth pattern into a malignant tumor) of mesothelial cells gives rise to malignant mesothelioma.

Contact a Specialist
Due to mesothelioma’s relative rarity among the general population, it is recommended that if you are diagnosed with mesothelioma that you be treated by a team of doctors and surgeons led by a mesothelioma specialist. Mesothelioma specialists are aware of the latest research and they are able to develop a more informed treatment plan than would a physician who does not specialize in the disease.

Mesothelioma Drugs

noreply@blogger.com (Maksim Reshetnikov) — Tue, 30 Mar 2010 08:07:00 +0000

A diagnosis of mesothelioma will normally be followed by several discussions with your oncologist. Such topics of discussion will cover prognosis and treatment options to battle the disease. More often than not, the course of treatment can include a variety of mesothelioma medications.

Mesothelioma & Chemotherapy

Chemotherapy medications have been used to treat cancer since the 1950s. Many of the older ones are obsolete and have been replaced by newer, more successful drugs. An oncologist will determine which chemotherapy medication is best for you. In addition to chemotherapy, surgery or radiation may also be recommended.

Chemotherapy can be administered at a hospital, doctor's office, or in a clinic setting that caters only to cancer patients. Such treatment is most commonly administered intravenously through a catheter or directly into a vein. Some chemotherapy medications come in pill or liquid form and will be swallowed under the supervision of a doctor. Others can be taken at home following the strict instructions of a medical professional.

The dosage of the medication will be determined by your doctor and may include daily treatments for a specific time. Though chemotherapy can be very helpful, it can carry a number of side effects. Some mesothelioma patients will experience none at all while others may be shouldered with several uncomfortable side effects. These include nausea, vomiting, fatigue, loss of appetite, weight loss, hair loss, bruising or bleeding, and an increased susceptibility to infection.

Chemotherapy Medications for Mesothelioma Patients

Today's most commonly used chemotherapy medication for mesothelioma is Alimta. Currently, this drug is the only FDA-approved medication specifically designed for the treatment of malignant mesothelioma when surgery is not an option. It is generally used in combination with another chemotherapy drug called cisplatin, a platinum-based drug. Together, the two have shown promise in prolonging and improving the quality of life of mesothelioma patients. Other chemotherapy drugs sometimes used for mesothelioma treatment include carboplatin, onconase, gemcitabine, and navelbine.

Other Medications for Mesothelioma Patients

Most mesothelioma patients' drug regimens are not limited to chemotherapy medications. It is often necessary to take other medications to help combat the symptoms and side effects of the disease. Those who take the time to find the right combination of pain medications indicate a marked difference in their quality of life. However, patients should never take pain medications without consulting their doctor. In some cases, doctors will also recommend the use of anti-nausea drugs for chemotherapy patients. Anti-nausea drugs for nausea include Compazine, Torecan, Zofran and Kytril.

Types of Asbestos

noreply@blogger.com (Maksim Reshetnikov) — Tue, 30 Mar 2010 08:06:00 +0000

The six recognized asbestos minerals, which are considered silicates (molecules that include silicon and oxygen), include:

Chrysotile - (Also known as white or green asbestos, from the Greek word meaning "fine, silky hair") Appears as curly, whitish fibers and constitutes 95 percent of the asbestos in use. Chrysotile is mined throughout the world, but most of the United State's chrysotile supply comes from Canada, Africa, and former USSR. Scientists believe this to be the least toxic of all asbestos forms.
Crocidolite - (Also known as riebeckite or blue asbestos) Composed of straight fibers, most crocidolite comes from southern Africa and Australia. It is believed to be the most toxic form of all asbestos minerals.
Amosite - (Also known as cummingtonite-grunerite or brown asbestos) The trade name "amosite" is an acronym for Asbestos Mines of South Africa, after the Amosa mines. Amosite is also straight in shape, but brittle in structure and excellent for use in heat insulation.
Anthophyllite - This form of asbestos is brittle, white, and contains various forms of iron. It has been found to have excellent resistance to chemicals and heat.
Tremolite - In rough form, tremolite appears white and chalky. Tremolite can also be naturally found in other mineral forms aside from asbestiform. It has been the major ingredient in industrial and commercial talc.
Actinolite - Typically prismatic, flat in structure, and elongated. Actinolite also comes in forms other than asbestiform and has poor resistance to chemicals.

The last five amphibole (which translates to "ambiguous" in Greek) types have a slightly more complex crystal structure than chrysotile and are not used as extensively in commercial products as chrysotile. Due to their structure, amphiboles tend to stay in the lungs longer than chrysotile and are more likely to cause illness because of this factor. Some hypothesize very small contaminations of amphibole fibers within chrysotile are most to blame for cancer deaths caused by asbestos exposure.

Asbestiform minerals are found in serpentine and ultramafic rock. These rocks are located throughout the United States, especially near mountainous regions. California is exceptionally bountiful in asbestos, where the mineral can be found in at least 44 of the state's 58 counties (some geologists report asbestos is found in 50 of the 58 counties). Asbestos fibers especially form near fault zones, where temperature, pressure, and time have transformed the molecules into the asbestiform crystals.

What is Asbestos?

noreply@blogger.com (Maksim Reshetnikov) — Tue, 30 Mar 2010 08:05:00 +0000

The term "asbestos" has been given to six naturally occurring mineral fibers that have been used for commercial purposes. It can be found in hundreds of countries on just about every continent. These fibers belong to two separate mineral groups, known as serpentine and amphibole.

A Detailed Diagram of Where Asbestos Can Be Found in the Home

The serpentine group, usually of a curly form, contains only one asbestiform variety, referred to as chrysotile. The amphibole group, which is straight and needle-like, contains five asbestiform varieties: anthophyllite, grunerite (amosite), riebeckite (crocidolite), tremolite, and actinolite.

The U.S. Bureau of Mines has listed more than 100 mineral fibers as "asbestos-like" fibers, but the United States government only regulates the six aforementioned forms (primarily due to effective lobbying on behalf of the asbestos and stone industries).

These very fine fibers are separable, hundreds of times thinner than human hairs, and too small to be seen with the naked eye. The Occupational Safety and Health Administration (OSHA) defines fibers of concern as at least five micrometers long and at least three times as long as their diameters. For a frame of reference, mineralogists work with fibers as much as a thousand times as long as their diameters.

Additional Risk Factors

noreply@blogger.com (Maksim Reshetnikov) — Tue, 30 Mar 2010 08:01:00 +0000

Other risk factors that may cause malignant mesothelioma include:

Radiation: Some mesothelioma patients with no traceable history of asbestos exposure do share a history of radiation exposure. Around 45 cases of mesothelioma following radiation therapy have been reported and discussed in medical literature.
Nonasbestos Mineral Fibers: A few nonasbestos mineral fibers have been linked to malignant mesothelioma, such as erionite and taconite.
Simian Virus 40: Originating in the rhesus monkey and contaminating millions of polio vaccines administered in the 1950s and ’60s, simian virus 40 has been linked to malignant mesothelioma and several other malignancies.

Additional risk factors that are not as well-researched in medical literature include chronic inflammation, chest injuries, genetics and organic chemicals.

It should be noted that cancer doctors and research scientists know that smoking does not cause mesothelioma, but it can aggravate other asbestos-related conditions (such as asbestosis) and compromises the body’s ability to fight the biological effects of asbestos fibers. Additionally, asbestos exposure and smoking has a synergistic affect that can increase a person's risk of developing lung cancer by as much as 84 times or more. For this reason, those who have been exposed to asbestos are highly advised not to smoke.

Mesothelioma Diagnosis

noreply@blogger.com (Maksim Reshetnikov) — Tue, 30 Mar 2010 08:00:00 +0000

A medical exam is the first step in diagnosing an asbestos-related illness.

The process of mesothelioma diagnosis usually begins with a review of a patient’s medical history followed by a physical examination.

If a problem is suspected, a doctor may request several diagnostic tests. These typically include medical imaging scans such as:

X-rays
CT scans
PET scans
MRI scans

A combination of these tests is often used to determine the location, size and type of the cancer. Biopsy procedures are often requested following an imaging scan to test samples of fluid and tissue for the presence of cancerous cells.

Mesothelioma Symptoms

noreply@blogger.com (Maksim Reshetnikov) — Tue, 30 Mar 2010 07:58:00 +0000

A patient with mesothelioma often demonstrates symptoms 15 to 50 years after initial exposure to asbestos. The cancer may take decades to develop in the body and symptoms do not arise until after the cancer is present. Many patients are unaware of the severity of their condition since mesothelioma symptoms typically resemble symptoms of less serious illnesses.

If you have a history of asbestos exposure, the leading cause of mesothelioma, it is best to seek immediate medical advice. Informing your doctor of previous asbestos exposure can alert them to the possibility of an asbestos-related disease such as mesothelioma.

Mesothelioma Types

noreply@blogger.com (Maksim Reshetnikov) — Tue, 30 Mar 2010 07:57:00 +0000

There are five known types of mesothelioma. The four listed below are malignant cancers, and benign mesothelioma is a non-cancerous condition.

Once asbestos is inhaled it can effect many of the bodys different organs including the throat, lungs, stomach, heart and testicles.

Pleural Mesothelioma: This type of mesothelioma develops in the lining of the lungs, known as the pleura. It is the most common form of malignant mesothelioma, with around 75 percent of cases being pleural in origin.

Peritoneal Mesothelioma: Comprising approximately 20 percent of mesothelioma cases, this form of mesothelioma develops in the lining of the abdominal cavity, known as the peritoneal membrane.

Pericardial Mesothelioma: This form of mesothelioma develops in the lining of the heart, known as the pericardium. Approximately 5 percent of all mesothelioma cases are pericardial.

Testicular Mesothelioma: Testicular mesothelioma develops in the tunica vaginalis of the testicles and is the rarest form of the cancer.

Mesothelioma Causes

noreply@blogger.com (Maksim Reshetnikov) — Tue, 30 Mar 2010 07:44:00 +0000

Mesothelioma is a rare cancer that can develop in the membrane that lines the lungs, called the mesothelium.

Mesothelioma is caused by asbestos exposure which occurs when fibers are inhaled or ingested into the body and become lodged in body cavities, causing inflammation or infection. Asbestos is a naturally-occurring fibrous substance that was widely used in the 20th century in a number of different industries. When the public became aware of the hazards associated with the mineral, warnings were issued in the mid-1970s and use of the product began to decline.

More than 30 percent of those diagnosed with mesothelioma are veterans. Please visit the page on asbestos for additional information about the mineral.

Mesothelioma

Mesothelioma is a rare type of cancer that typically affects the lining of the lungs, heart and abdomen. Approximately 2,000 to 3,000 cases of mesothelioma are diagnosed each year in the United States, comprising around 3 percent of all cancer diagnoses. This cancer occurs about four times more frequently in men than in women and all forms of mesothelioma, except for benign mesothelioma, are invariably fatal.

The life expectancy for mesothelioma patients is generally reported as less than one year following diagnosis, however a patient’s prognosis is affected by numerous factors including how early the cancer is diagnosed and how aggressively it is treated.
