What are the side effects of treatment for brain tumors?

2008-11-20T00:48:00.000-08:00

Because treatment may damage healthy cells and tissues, unwanted side effects are common. These side effects depend on many factors, including the location of the tumor and the type and extent of the treatment. Side effects may not be the same for each person, and they may even change from one treatment session to the next. Before treatment starts, the health care team will explain possible side effects and suggest ways to help the patient manage them.

Surgery

Patients often have a headache or are uncomfortable for the first few days after surgery. However, medicine can usually control their pain. Patients should feel free to discuss pain relief with the doctor or nurse.

It is also common for patients to feel tired or weak. The length of time it takes to recover from an operation varies for each patient.

Other, less common, problems may occur. Cerebrospinal fluid or blood may build up in the brain. This swelling is called edema. The health care team monitors the patient for signs of these problems. The patient may receive steroids to help relieve swelling. A second surgery may be needed to drain the fluid. The surgeon may place a long, thin tube (shunt) in a ventricle of the brain. The tube is threaded under the skin to another part of the body, usually the abdomen. Excess fluid is carried from the brain and drained into the abdomen. Sometimes the fluid is drained into the heart instead.

Infection is another problem that may develop after surgery. If this happens, the health care team gives the patient an antibiotic.

Brain surgery may damage normal tissue. Brain damage can be a serious problem. The patient may have problems thinking, seeing, or speaking. The patient also may have personality changes or seizures. Most of these problems lessen or disappear with time. But sometimes damage to the brain is permanent. The patient may need physical therapy, speech therapy, or occupational therapy.

Radiation Therapy

Some patients have nausea for several hours after treatment. The health care team can suggest ways to help patients cope with this problem. Radiation therapy also may cause patients to become very tired as treatment continues. Resting is important, but doctors usually advise patients to try to stay as active as they can.

In addition, radiation therapy commonly causes hair loss. Hair usually grows back within a few months. Radiation therapy also may affect the skin in the treated area. The scalp and ears may become red, dry, and tender. The health care team can suggest ways to relieve these problems.

Sometimes radiation therapy causes brain tissue to swell. Patients may get a headache or feel pressure. The health care team watches for signs of this problem. They can provide medicine to reduce the discomfort.

Radiation sometimes kills healthy brain tissue. This side effect is called radiation necrosis. Necrosis can cause headaches, seizures, or even the patient's death.

In children, radiation may damage the pituitary gland and other areas of the brain. This could cause learning problems or slow down growth and development. In addition, radiation during childhood increases the risk of secondary tumors later in life. Researchers are studying whether chemotherapy may be used instead of radiation therapy in young children with brain tumors.

Side effects may be worse if chemotherapy and radiation therapy are given at the same time. The doctor can suggest ways to ease these problems.

Chemotherapy

The side effects of chemotherapy depend mainly on the drugs that are used. The most common side effects include fever and chills, nausea and vomiting, loss of appetite, and weakness. Some side effects may be relieved with medicine.

Patients who receive an implant (a wafer) that contains a drug are monitored by the health care team for signs of infection after surgery. An infection can be treated with an antibiotic.

Supportive Care

At any stage of disease, people with brain tumors receive supportive care to prevent or control problems and to improve their comfort and quality of life during treatment. Patients may have treatment to control pain and other symptoms of a brain tumor, to relieve the side effects of therapy, and to ease emotional problems.

These are common types of supportive care for people with brain tumors:

Steroids - Most patients with brain tumors need steroids to help relieve swelling of the brain.
Anticonvulsant medicine - Brain tumors can cause seizures. Patients may take an anticonvulsant medicine to prevent or control seizures.
Shunt - If fluid builds up in the brain, the surgeon may place a shunt to drain the fluid. Information about shunts is under "Surgery" in the "Side Effects" section.

Many people with brain tumors receive supportive care along with treatments intended to slow the progress of the disease. Some decide not to have antitumor treatment and receive only supportive care to manage their symptoms.

What about rehabilitation after treatment for brain tumors?

2008-11-19T00:43:00.000-08:00

Rehabilitation can be a very important part of the treatment plan. The goals of rehabilitation depend on the person's needs and how the tumor has affected daily activities. The health care team makes every effort to help the patient return to normal activities as soon as possible. Several types of therapists can help:

Physical therapists - Brain tumors and their treatment may cause paralysis. They may also cause weakness and problems with balance. Physical therapists help patients regain strength and balance.
Speech therapists - Speech therapists help patients who have trouble speaking, expressing thoughts, or swallowing.
Occupational therapists - Occupational therapists help patients learn to manage activities of daily living, such as eating, using the toilet, bathing, and dressing.

Children with brain tumors may have special needs. Sometimes children have tutors in the hospital or at home. Children who have problems learning or remembering what they learn may need tutors or special classes when they return to school.

What happens after treatment for brain tumors?

Regular followup is very important after treatment for a brain tumor. The doctor checks closely to make sure that the tumor has not returned. Checkups may include careful physical and neurologic exams. From time to time, the patient may have MRI or CT scans. If the patient has a shunt, the doctor checks to see that it is working well. The doctor can explain the followup plan - how often the patient must visit the doctor and what tests will be needed.

What support is available to patients with brain tumors?

Living with a serious disease such as a brain tumor is not easy. Some people find they need help coping with the emotional and practical aspects of their disease. Support groups can help. In these groups, patients or their family members get together to share what they have learned about coping with the disease and the effects of treatment. Patients may want to talk with a member of their health care team about finding a support group. Groups may offer support in person, over the telephone, or on the Internet.

People living with a brain tumor may worry about caring for their families, keeping their jobs, or continuing daily activities. Concerns about treatments and managing side effects, hospital stays, and medical bills are also common. Doctors, nurses, and other members of the health care team can answer questions about treatment, working, or other activities. Meeting with a social worker, counselor, or member of the clergy can be helpful to those who want to talk about their feelings or discuss their concerns. Often, a social worker can suggest resources for financial aid, transportation, home care, or emotional support.

The Cancer Information Service can provide information to help patients and their families locate programs, services, and publications.

The promise of cancer research

Doctors all over the country are conducting many types of clinical trials. These are research studies in which people take part voluntarily. Studies include new ways to treat brain tumors. Research has already led to advances, and researchers continue to search for more effective approaches.

Patients who join these studies have the first chance to benefit from treatments that have shown promise in earlier research. They also make an important contribution to medical science by helping doctors learn more about the disease. Although clinical trials may pose some risks, researchers take very careful steps to protect their patients.

Researchers are testing new anticancer drugs, doses, and treatment schedules. They are working with various drugs and drug combinations, as well as combinations of drugs and radiation therapy. They also are testing new methods and schedules of radiation therapy.

Patients who are interested in being part of a clinical trial should talk with their doctor. NCI's Web site includes a section on clinical trials at http://www.cancer.gov/clinicaltrials. This section of the Web site provides general information about clinical trials. It also offers detailed information about ongoing studies of treatment for brain tumors. The Cancer Information Service at 1-800-4-CANCER can answer questions and provide information about clinical trials.

Preparing for Treatment

2008-11-18T00:35:00.000-08:00

The doctor can describe treatment choices and discuss the results expected with each treatment option. The doctor and patient can work together to develop a treatment plan that fits the patient's needs.

Treatment depends on a number of factors, including the type, location, size, and grade of the tumor. For some types of brain cancer, the doctor also needs to know whether cancer cells were found in the cerebrospinal fluid.

These are some questions a person may want to ask the doctor before treatment begins:

What type of brain tumor do I have?
Is it benign or malignant?
What is the grade of the tumor?
What are my treatment choices? Which do you recommend for me? Why?
What are the benefits of each kind of treatment?
What are the risks and possible side effects of each treatment?
What is the treatment likely to cost?
How will treatment affect my normal activities?
Would a clinical trial (research study) be appropriate for me? Can you help me find one?

People do not need to ask all of their questions or understand all of the answers at one time. They will have other chances to ask the doctor to explain things that are not clear and to ask for more information.

Methods of Treatment

2008-11-13T02:25:00.000-08:00

People with brain tumors have several treatment options. Depending on the tumor type and stage, patients may be treated with surgery, radiation therapy, or chemotherapy. Some patients receive a combination of treatments.

In addition, at any stage of disease, patients may have treatment to control pain and other symptoms of the cancer, to relieve the side effects of therapy, and to ease emotional problems. This kind of treatment is called symptom management, supportive care, or palliative care.
The doctor is the best person to describe the treatment choices and discuss the expected results.

A patient may want to talk to the doctor about taking part in a clinical trial, which is a research study of new treatment methods. The section on "The Promise of Cancer Research" has more information about clinical trials.

Surgery is the usual treatment for most brain tumors. Surgery to open the skull is called a craniotomy. It is performed under general anesthesia. Before surgery begins, the scalp is shaved. The surgeon then makes an incision in the scalp and uses a special type of saw to remove a piece of bone from the skull. After removing part or all of the tumor, the surgeon covers the opening in the skull with that piece of bone or with a piece of metal or fabric. The surgeon then closes the incision in the scalp.

These are some questions a person may want to ask the doctor before having surgery:
• How will I feel after the operation?
• What will you do for me if I have pain?
• How long will I be in the hospital?
• Will I have any long-term effects? Will my hair grow back? Are there any side effects from using metal or fabric to replace the bone in the skull?
• When can I get back to my normal activities?
• What is my chance of a full recovery?

Sometimes surgery is not possible. If the tumor is in the brain stem or certain other areas, the surgeon may not be able to remove the tumor without damaging normal brain tissue. Patients who cannot have surgery may receive radiation or other treatment.

Radiation therapy

Radiation therapy (also called radiotherapy) uses high-energy rays to kill tumor cells. The radiation may come from x-rays, gamma rays, or protons. A large machine aims radiation at the tumor and the tissue close to it. Sometimes the radiation may be directed to the entire brain or to the spinal cord.

Radiation therapy usually follows surgery. The radiation kills tumor cells that may remain in the area. Sometimes, patients who cannot have surgery have radiation therapy instead.
The patient goes to a hospital or clinic for radiation therapy. The treatment schedule depends on the type and size of the tumor and the age of the patient. Each treatment lasts only a few minutes.

Doctors take steps to protect the healthy tissue around the brain tumor:
• Fractionation - Radiation therapy usually is given five days a week for several weeks. Giving the total dose of radiation over an extended period helps to protect healthy tissue in the area of the tumor.
• Hyperfractionation - The patient gets smaller doses of radiation two or three times a day instead of a larger amount once a day.
• Stereotactic radiation therapy - Narrow beams of radiation are directed at the tumor from different angles. For this procedure, the patient wears a rigid head frame. An MRI or CT scan creates pictures of the tumor's exact location. The doctor uses a computer to decide on the dose of radiation needed, as well as the sizes and angles of the radiation beams. The therapy may be given during a single visit or over several visits.
• 3-dimensional conformal radiation therapy - A computer creates a 3-dimensional image of the tumor and nearby brain tissue. The doctor aims multiple radiation beams to the exact shape of the tumor. The precise focus of the radiation beams protects normal brain tissue.
• Proton beam radiation therapy - The source of radiation is protons rather than x-rays. The doctor aims the proton beams at the tumor. Protons can pass through healthy tissue without damaging it.
These are some questions a person may want to ask the doctor before having radiation therapy:
• Why do I need this treatment?
• When will the treatments begin? When will they end?
• How will I feel during therapy? Are there side effects?
• What can I do to take care of myself during therapy?
• How will we know if the radiation is working?
• Will I be able to continue my normal activities during treatment?

Chemotherapy

Chemotherapy, the use of drugs to kill cancer cells, is sometimes used to treat brain tumors. The drugs may be given by mouth or by injection. Either way, the drugs enter the bloodstream and travel throughout the body. The drugs are usually given in cycles so that a recovery period follows each treatment period.
Chemotherapy may be given in an outpatient part of the hospital, at the doctor's office, or at home. Rarely, the patient may need to stay in the hospital.
Children are more likely than adults to have chemotherapy. However, adults may have chemotherapy after surgery and radiation therapy.
For some patients with recurrent cancer of the brain, the surgeon removes the tumor and implants several wafers that contain chemotherapy. Each wafer is about the size of a dime. Over several weeks, the wafers dissolve, releasing the drug into the brain. The drug kills cancer cells.
Patients may want to ask these questions about chemotherapy:
• Why do I need this treatment?
• What will it do?
• Will I have side effects? What can I do about them?
• When will treatment start? When will it end?
• How often will I need checkups?

What is the treatment for brain tumors?

2008-11-11T23:25:00.000-08:00

Many people with brain tumors want to take an active part in making decisions about their medical care. They want to learn all they can about their disease and their treatment choices. However, shock and stress after a diagnosis of a brain tumor can make it hard to think of everything to ask the doctor. It often helps to make a list of questions before an appointment. To help remember what the doctor says, patients may take notes or ask whether they may use a tape recorder. Some also want to have a family member or friend with them when they talk to the doctor - to take part in the discussion, to take notes, or just to listen.

The doctor may refer the patient to a specialist, or the patient may ask for a referral. Specialists who treat brain tumors include neurosurgeons, neurooncologists, medical oncologists, and radiation oncologists. The patient may be referred to other health care professionals who work together as a team. The medical team may include a nurse, dietitian, mental health counselor, social worker, physical therapist, occupational therapist, and speech therapist. Children may need tutors to help with schoolwork. (The section on "Rehabilitation" has more information about therapists and tutors.)

Getting a second opinion

Before starting treatment, the patient might want a second opinion about the diagnosis and the treatment plan. Some insurance companies require a second opinion; others may cover a second opinion if the patient or doctor requests it.

There are a number of ways to find a doctor for a second opinion:

The patient's doctor may refer the patient to one or more specialists. At cancer centers, several specialists often work together as a team.
The Cancer Information Service, at 1-800-4-CANCER, can tell callers about nearby treatment centers.
A person with a brain tumor can request a consultation with a team of specialists in NCI's Neuro-Oncology Branch of the Warren Grant Magnuson Clinical Center at the National Institutes of Health in Bethesda, Maryland (301-402-6298).
A local or state medical society, a nearby hospital, or a medical school can usually provide the names of specialists.
The American Board of Medical Specialties (ABMS) has a list of doctors who have met certain education and training requirements and have passed specialty examinations. The Official ABMS Directory of Board Certified Medical Specialists lists doctors' names along with their specialty and their educational background. The directory is available in most public libraries. Also, ABMS offers this information on the Internet at http://www.abms.org. (Click on "Who's Certified.")

How are brain tumors diagnosed?

2008-11-03T01:44:00.000-08:00

If a person has symptoms that suggest a brain tumor, the doctor may perform one or more of the following procedures:

Physical exam - The doctor checks general signs of health.
Neurologic exam - The doctor checks for alertness, muscle strength, coordination, reflexes, and response to pain. The doctor also examines the eyes to look for swelling caused by a tumor pressing on the nerve that connects the eye and brain.
CT scan - An x-ray machine linked to a computer takes a series of detailed pictures of the head. The patient may receive an injection of a special dye so the brain shows up clearly in the pictures. The pictures can show tumors in the brain.
MRI - A powerful magnet linked to a computer makes detailed pictures of areas inside the body. These pictures are viewed on a monitor and can also be printed. Sometimes a special dye is injected to help show differences in the tissues of the brain. The pictures can show a tumor or other problem in the brain.

The doctor may ask for other tests:

Angiogram - Dye injected into the bloodstream flows into the blood vessels in the brain to make them show up on an x-ray. If a tumor is present, the doctor may be able to see it on the x-ray.
Skull x-ray - Some types of brain tumors cause calcium deposits in the brain or changes in the bones of the skull. With an x-ray, the doctor can check for these changes.
Spinal tap - The doctor may remove a sample of cerebrospinal fluid (the fluid that fills the spaces in and around the brain and spinal cord). This procedure is performed with local anesthesia. The doctor uses a long, thin needle to remove fluid from the spinal column. A spinal tap takes about 30 minutes. The patient must lie flat for several hours afterward to keep from getting a headache. A laboratory checks the fluid for cancer cells or other signs of problems.
Myelogram - This is an x-ray of the spine. A spinal tap is performed to inject a special dye into the cerebrospinal fluid. The patient is tilted to allow the dye to mix with the fluid. This test helps the doctor detect a tumor in the spinal cord.
Biopsy - The removal of tissue to look for tumor cells is called a biopsy. A pathologist looks at the cells under a microscope to check for abnormal cells. A biopsy can show cancer, tissue changes that may lead to cancer, and other conditions. A biopsy is the only sure way to diagnose a brain tumor.
Surgeons can obtain tissue to look for tumor cells in three ways:

Needle biopsy - The surgeon makes a small incision in the scalp and drills a small hole into the skull. This is called a burr hole. The doctor passes a needle through the burr hole and removes a sample of tissue from the brain tumor.
Stereotactic biopsy - An imaging device, such as CT or MRI, guides the needle through the burr hole to the location of the tumor. The surgeon withdraws a sample of tissue with the needle.
Biopsy at the same time as treatment - Sometimes the surgeon takes a tissue sample when the patient has surgery to remove the tumor.

Sometimes a biopsy is not possible. If the tumor is in the brain stem or certain other areas, the surgeon may not be able to remove tissue from the tumor without damaging normal brain tissue. The doctor uses MRI, CT, or other imaging tests instead.

A person who needs a biopsy may want to ask the doctor the following questions:

Why do I need a biopsy? How will the biopsy affect my treatment plan?
What kind of biopsy will I have?
How long will it take? Will I be awake? Will it hurt?
What are the chances of infection or bleeding after the biopsy? Are there any other risks?
How soon will I know the results?
If I do have a brain tumor, who will talk to me about treatment? When?

Benign or Malignant Brain Tumor ?

2008-09-22T23:04:00.000-07:00

Brain tumors can be benign or malignant:

Benign brain tumors do not contain cancer cells:

Usually, benign tumors can be removed, and they seldom grow back.
The border or edge of a benign brain tumor can be clearly seen. Cells from benign tumors do not invade tissues around them or spread to other parts of the body. However, benign tumors can press on sensitive areas of the brain and cause serious health problems.
Unlike benign tumors in most other parts of the body, benign brain tumors are sometimes life threatening.
Very rarely, a benign brain tumor may become malignant.

Malignant brain tumors contain cancer cells:

Malignant brain tumors are generally more serious and often are life threatening.
They are likely to grow rapidly and crowd or invade the surrounding healthy brain tissue.
Very rarely, cancer cells may break away from a malignant brain tumor and spread to other parts of the brain, to the spinal cord, or even to other parts of the body. The spread of cancer is called metastasis.
Sometimes, a malignant tumor does not extend into healthy tissue. The tumor may be contained within a layer of tissue. Or the bones of the skull or another structure in the head may confine it. This kind of tumor is called encapsulated.

Tumor Grade

Doctors sometimes group brain tumors by grade - from low grade (grade I) to high grade (grade IV). The grade of a tumor refers to the way the cells look under a microscope. Cells from high-grade tumors look more abnormal and generally grow faster than cells from low-grade tumors.

Brain Tumor Symptom

2008-09-19T00:28:00.000-07:00

The brain tumor symptom of brain tumors depend on tumor size, type, and location. Symptoms may be caused when a tumor presses on a nerve or damages a certain area of the brain. They also may be caused when the brain swells or fluid builds up within the skull.

These are the most common symptoms of brain tumors:

Headaches (usually worse in the morning)
Nausea or vomiting
Changes in speech, vision, or hearing
Problems balancing or walking
Changes in mood, personality, or ability to concentrate
Problems with memory
Muscle jerking or twitching (seizures or convulsions)
Numbness or tingling in the arms or legs

These symptoms are not sure signs of a brain tumor. Other conditions also could cause these problems. Anyone with these symptoms should see a doctor as soon as possible. Only a doctor can diagnose and treat the problem.

Classification - Secondary Brain Tumor

2008-09-17T02:15:00.000-07:00

When cancer spreads from its original place to another part of the body, the new tumor has the same kind of abnormal cells and the same name as the primary tumor. Cancer that spreads to the brain from another part of the body is different from a primary brain tumor. When cancer cells spread to the brain from another organ (such as the lung or breast), doctors may call the tumor in the brain a secondary tumor or metastatic tumor. Secondary tumors in the brain are far more common than primary brain tumors.

What causes and who is at risk for brain tumors?

No one knows the exact causes of brain tumors. Doctors can seldom explain why one person develops a brain tumor and another does not. However, it is clear that brain tumors are not contagious. No one can "catch" the disease from another person.

Research has shown that people with certain risk factors are more likely than others to develop a brain tumor. A risk factor is anything that increases a person's chance of developing a disease.

The following risk factors are associated with an increased chance of developing a primary brain tumor:

Being male - In general, brain tumors are more common in males than females. However, meningiomas are more common in females.
Race - Brain tumors occur more often among white people than among people of other races.
Age - Most brain tumors are detected in people who are 70 years old or older. However, brain tumors are the second most common cancer in children. (Leukemia is the most common childhood cancer.) Brain tumors are more common in children younger than 8 years old than in older children.
Family history - People with family members who have gliomas may be more likely to develop this disease.
Being exposed to radiation or certain chemicals at work:

Radiation - Workers in the nuclear industry have an increased risk of developing a brain tumor.
Formaldehyde - Pathologists and embalmers who work with formaldehyde have an increased risk of developing brain cancer. Scientists have not found an increased risk of brain cancer among other types of workers exposed to formaldehyde.
Vinyl chloride - Workers who make plastics may be exposed to vinyl chloride. This chemical may increase the risk of brain tumors.
Acrylonitrile - People who make textiles and plastics may be exposed to acrylonitrile. This exposure may increase the risk of brain cancer.

Scientists are investigating whether cell phones may cause brain tumors. Studies thus far have not found an increased risk of brain tumors among people who use cell phones.

Scientists also continue to study whether head injuries are a risk factor for brain tumors. So far, these studies have not found an increased risk among people who have had head injuries.

Most people who have known risk factors do not get brain cancer. On the other hand, many who do get the disease have none of these risk factors. People who think they may be at risk should discuss this concern with their doctor. The doctor may be able to suggest ways to reduce the risk and can plan an appropriate schedule for checkups.

Classification - Primary Brain Tumor

2008-09-16T00:34:00.000-07:00

Brain Tumor begin in brain tissue, the so-called primary tumors of the brain. (For information on secondary brain tumors appears in the next section.) Primary brain tumors are named after the type of cells or part of the brain, where they begin

The most common primary brain tumors are gliomas. They begin in glial cells. There are many types of gliomas:

astrocytoma - The tumor arises from glial cells called astrocytes. In adults, astrocytomas most frequently occur in the cerebrum. In children, they occur in the brain stem, the cerebrum and cerebellum. A Class III astrocytoma is sometimes a so-called anaplastic astrocytoma. A class IV astrocytoma is usually referred to as glioblastoma multiforme.
brain stem glioma - The tumor occurs in the lowest part of the brain. Brainstem gliomas are the most commonly diagnosed in young children and middle-aged adults.
Ependymoma - The tumor cells, it is clear from this line of the chambers or the central canal of the spinal cord. They are most often in children and young adults.
Oligodendroglioma - This arises from rare tumor cells, which fatty substance that covers and protects the nerves. These tumors usually in the cerebrum. They grow slowly and not spread into surrounding brain tissue. They are most often in middle-aged adults.

Some types of brain tumors do not begin in glial cells. The most common are:

medulloblastoma - This cancer usually arises in the cerebellum. It is the most common brain tumors in children. It is sometimes also a primitive neuroectodermal tumor.
Meningioma - This tumor is in the meninges. It grows slowly.
Schwannoma - that a tumor arises from a Schwann cells. These cells line the nerve that controls balance and hearing. This is nerve in the inner ear. The tumor is also an acoustic neuroma. It occurs most frequently in adults.
Craniopharyngioma - The growing tumor at the base of the brain near the pituitary gland. This type of tumor occurs most often in children.
germ cell tumor of the brain - the tumor arises from a germ cell. Most germ cell tumors in the brain that occur in people younger than 30th The most common type of germ cell tumor of the brain is a Germinoma.
pineal region tumor - This is rare brain tumor in or near the pineal gland. The pineal gland is located between the cerebrum and cerebellum.

Brain Tumor

2008-09-14T18:32:00.000-07:00

A brain tumor is any intracranial tumor created by abnormal and uncontrolled cell division, normally either in the brain itself (neurons, glial cells (astrocytes, oligodendrocytes, ependymal cells), lymphatic tissue, blood vessels), in the cranial nerves (myelin-producing Schwann cells), in the brain envelopes (meninges), skull, pituitary and pineal gland, or spread from cancers primarily located in other organs (metastatic tumors). Primary (true) brain tumors are commonly located in the posterior cranial fossa in children and in the anterior two-thirds of the cerebral hemispheres in adults, although they can affect any part of the brain. In the United States in the year 2005, it was estimated that there were 43,800 new cases of brain tumors (Central Brain Tumor Registry of the United States, Primary Brain Tumors in the United States, Statistical Report, 2005 - 2006), which accounted for 1.4 percent of all cancers, 2.4 percent of all cancer deaths, and 20–25 percent of pediatric cancers. Ultimately, it is estimated that there are 13,000 deaths per year in the United States alone as a result of brain tumors.

What is the brain

2008-09-09T23:31:00.001-07:00

The brain is a soft, spongy mass of tissue. It is protected by the bones of the skull and three thin membranes called meninges. Watery fluid called cerebrospinal fluid cushions the brain. This fluid flows through spaces between the meninges and through spaces within the brain called ventricles.

A network of nerves carries messages back and forth between the brain and the rest of the body. Some nerves go directly from the brain to the eyes, ears, and other parts of the head. Other nerves run through the spinal cord to connect the brain with the other parts of the body. Within the brain and spinal cord, glial cells surround nerve cells and hold them in place.

The brain directs the things we choose to do (like walking and talking) and the things our body does without thinking (like breathing). The brain is also in charge of our senses (sight, hearing, touch, taste, and smell), memory, emotions, and personality.

The three major parts of the brain control different activities:

Cerebrum - The cerebrum is the largest part of the brain. It is at the top of the brain. It uses information from our senses to tell us what is going on around us and tells our body how to respond. It controls reading, thinking, learning, speech, and emotions.

The cerebrum is divided into the left and right cerebral hemispheres, which control separate activities. The right hemisphere controls the muscles on the left side of the body. The left hemisphere controls the muscles on the right side of the body.

Cerebellum - The cerebellum is under the cerebrum at the back of the brain. The cerebellum controls balance and complex actions like walking and talking.
Brain Stem - The brain stem connects the brain with the spinal cord. It controls hunger and thirst. It also controls breathing, body temperature, blood pressure, and other basic body functions.
