Together, the brain and spinal cord form the central nervous system. This
complex system is part of everything we do. It controls the things we choose to
do,like walk and talk,and the things our body does automatically,like breathe
and digest food. The central nervous system is also involved with our senses;
seeing, hearing, touching, tasting, and smelling, as well as our emotions,
thoughts, and memory.
The brain is a soft, spongy mass of nerve cells and supportive tissue. It has
three major parts: the cerebrum, the cerebellum, and the brain stem. The parts
work together, but each has special functions.
The cerebrum, the largest part of the brain, fills most of the upper skull. It
has two halves called the left and right cerebral hemispheres. The cerebrum uses
information from our senses to tell us what is going on around us and tells our
body how to respond. The right hemisphere controls the muscles on the left side
of the body, and the left hemisphere controls the muscles on the right side of
the body. This part of the brain also controls speech and emotions as well as
reading, thinking, and learning.
The cerebellum, under the cerebrum at the back of the brain, controls balance
and complex actions like walking and talking.
The brain stem connects the brain with the spinal cord. It controls hunger and
thirst and some of the most basic body function, such as body temperature, blood
pressure, and breathing.
The brain is protected by the bones of the skull and by a covering of three thin
membranes called meninges. The brain is also cushioned and protected by
cerebrospinal fluid. This watery fluid is produced by special cells in the four
hollow spaces in the brain, called ventricles. It flows through the ventricles
and in spaces between the meninges. Cerebrospinal fluid also brings nutrients
from the blood to the brain and removes waste products from the brain.
The spinal cord is made up of bundles of nerve fibers. It runs down from the
brain through a canal in the center of the bones of the spine. These bones
protect the spinal cord. Like the brain, the spinal cord is covered by the
meninges and cushioned by brospinal fluid.
Spinal nerves connect the brain with the nerves in most parts of the body. Other
nerves go directly from the brain to the eyes, ears, and other parts of the
head. This network of nerves carries messages back and forth between the brain
and the rest of the body.

The body is made up of many types of cells. Each type of cell has special
functions. Most cells in the body grow and then divide in an orderly way to form
new cells as they are needed to keep the body healthy and working properly. When
cells lose the ability to control their growth, they divide too often and
without any order. The extra cells form a mass of tissue called a tumor. Each
year, more than 16,000 people find out they have a brain tumor. Tumors are
benign or malignant.
Benign brain tumors do not contain cancer cells. Usually these tumors can be
removed, and they are not likely to recur. Benign brain tumors have clear
borders. Although they do not invade nearby tissue, they can press on sensitive
areas of the brain and cause symptoms.
Malignant brain tumors contain cancer cells. They interfere with vital functions
and are life-threatening. Malignant brain tumors are likely to grow rapidly and
crowd or invade the tissue around them. Like a plant, these tumors may put out
"roots" that grow into healthy brain tissue. If a malignant tumor remains
compact and does not have roots, it is said to be encapsulated. When an
otherwise benign tumor is located in a vital area of the brain and interferes
with vital functions, it may be considered malignant (even though it contains no
cancer cells).
Doctors refer to some 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 higher grade tumors are more abnormal looking and
generally grow faster than cells from lower grade tumors; higher grade tumors
are more malignant than lower grade tumors.
(return to Top)
The causes of brain tumors are not known. Researchers are trying to solve this
problem. The more they can find out about the causes of brain tumors, the better
the chances of finding ways to prevent them.
Doctors cannot explain why one person gets a brain tumor and another doesn't,
but they do know that no one can "catch" a brain tumor from another person.
Brain tumors are not contagious
Although brain tumors can occur at any age, studies show that they are most
common in two age groups. The first group is children 3 to 12 years old; the
second is adults 40 to 70 years old.
By studying large numbers of patients, researchers have found certain risk
factors that increase a person's chance of developing a brain tumor. People with
these risk factors have a higher-than-average risk of getting a brain tumor. For
example, studies show that some types of brain tumors are more frequent among
workers in certain industries, such as oil refining, rubber manufacturing, and
drug manufacturing.
Other studies have shown that chemists and embalmers have a higher incidence of
brain tumors. Researchers also are looking at exposure to viruses as a possible
cause. Because brain tumors sometimes occur in several members of the same
family, researchers are studying families with a history of brain tumors to see
whether heredity is a cause. At this time, scientists do not believe that head
injuries cause brain tumors to develop.
In most cases, patients with a brain tumor have no clear risk factors. The
disease is probably the result of several factors acting together.
(return to Top)
Tumors that begin in the brain tissue are known as primary brain tumors.
Secondary tumors are those that develop when cancer spreads to the brain.
Primary brain tumors are classified by the type of tissue in which they begin.
The most common brain tumors are gliomas, which begin in the glial (supportive)
tissue. There are several types of gliomas:
Astrocytomas arise from small, star-shaped cells called astrocytes. They may
grow anywhere in the brain or spinal cord. In adults, astrocytomas most often
arise in the brain. In children, they occur in the brain stem, the cerebrum,
and the cerebellum. A grade III astrocytoma is sometimes called anaplastic
astrocytoma. A grade IV astrocytoma is usually called glioblastoma multiforme.
Brain stem gliomas occur in the lowest, stemlike part of the brain. The brain
stem controls many vital functions. Tumors in this area generally cannot be
removed. Most brain stem gliomas are high-grade astrocytomas.
Ependynomas usually develop in the lining of the ventricles. They also may occur
in the spinal cord. Although these tumors can develop at any age, they are most
common in childhood and adolescence.
Oligodendrogliomas arise in the cells that produce myelin, the fatty covering
that protects nerves. These tumors usually arise in the brain. They grow
slowly and usually do not spread into surrounding brain tissue.
Oligodendrogliomas are rare. They occur most often in middle- aged adults but
have been found in people of all ages.
There are other types of brain tumors that do not begin in glial tissue. Some of
the most common are described below:
Medulloblastomas were once thought to develop from glial cells. However, recent
research suggests that these tumors develop from primitive (developing) nerve
cells that normally do not remain in the body after birth. For this reason,
medulloblastomas are sometimes called primitive neuroectodermal tumors (PNET).
Most medulloblastomas arise in the cerebellum; however, they may occur in other
areas as well. These tumors occur most often in children and are more common in
boys than in girls.
Meningiomas grow from the meninges. They are usually benign. Because these
tumors grow very slowly, the brain may be able to adjust to their presence;
meningiomas often grow quite large before they cause symptoms. They occur most
often in women between 30 and 50 years of age. Schwannomas are benign tumors
that begin in Schwann cells, which produce the myelin that protects the acoustic
nerve, the nerve of hearing. Acoustic neuromas are a type of schwannoma. They
occur mainly in adults. These tumors affect women twice as often as men.
Craniopharyngiomas develop in the region of the pituitary gland near the
hypothalamus. They are usually benign; however, they are sometimes considered
malignant because they can press on or damage the hypothalamus and affect vital
functions. These tumors occur most often in children and adolescents.
Germ cell tumors arise from primitive (developing) sex cells, or germ cells. The
most frequent type of germ cell tumor in the brain is the germinoma.
Pineal region tumors occur in or around the pineal gland, a tiny organ near the
center of the brain. The tumor can be slow growing (pineocytoma) or fast growing
(pineoblastoma). The pineal region is very difficult to reach, and these tumors
often cannot be removed
(return to Top)
Metastasis is the spread of cancer. Cancer that begins in other parts of the
body may spread to the brain and cause secondary tumors. These tumors are not
the same as primary brain tumors. Cancer that spreads to the brain is the same
disease and has the same name as the original (primary) cancer. For example, if
lung cancer spreads to the brain, the disease is called metastatic lung cancer
because the cells in the secondary tumor resemble abnormal lung cells, not
abnormal brain cells.
Treatment for secondary brain tumors depends on where the cancer started and the
extent of the spread, as well as other factors, including the patient's age,
general health, and response to previous treatment.
(return to Top)
The symptoms of brain tumors depend mainly on their size and their location in
the brain. Symptoms are caused by damage to vital tissue and by pressure on the
brain as the tumor grows within the limited space in the skull. They also may be
caused by swelling and a buildup of fluid around the tumor, a condition called
edema . Symptoms also may be due to hydrocephalus , which occurs when the tumor
blocks the flow of cerebrospinal fluid and causes it to build up in the
ventricles. If a brain tumor grows very slowly, its symptoms may appear so
gradually that they are overlooked for a long time.
The most frequent symptoms of brain tumors include:
- Headaches that tend to be worse in the morning and ease during the day
- Seizures (convulsions)
- Nausea or vomiting
- Weakness or loss of feeling in the arms or legs
- Stumbling or lack of coordination in walking (ataxic gait)
- Abnormal eye movements or changes in vision
- Drowsiness
- Changes in personality or memory
- Changes in speech
These symptoms may be caused by brain tumors or by other problems. If an
individual is experiencing symptoms, they should consult a doctor right
away.
(return to Top)
To find the cause of a person's symptoms, the doctor asks about the patient's
personal and family medical history and does a complete physical examination. In
addition to checking general signs of health, the doctor does a neurological exam.
This includes checks for alertness, muscle strength, coordination, reflexes, and
response to pain. The doctor also examines the eyes to check for swelling caused
by a tumor pressing on the nerve that connects the eye and the brain.
Depending on the results of the physical and neurological examinations, the doctor
may request one or both of the following:
A CT (or CAT) scan is a series of detailed pictures of the brain. The pictures
are created by a computer linked to an x-ray machine. In some cases, a special
dye is injected into a vein before the scan. The dye helps to show differences
in the tissues of the brain
MRI (magnetic resonance imaging) gives pictures of the brain, using a powerful
magnet linked to a computer. MRI is especially useful in diagnosing brain tumors
because it can "see" through the bones of the skull to the tissue underneath. A
special dye may be used to enhance the likelihood of detecting a brain tumor
The doctor also may request other tests:
A skull x-ray can show changes in the bones of the skull caused by a tumor. It
can also show calcium deposits, which are present in some types of brain tumors
In a brain scan, areas of abnormal growth in the brain are revealed and recorded
on special film. A small amount of a radioactive material is injected into a
vein. This dye is absorbed by the tumor, and the growth shows up on the film
(the radiation leaves the body within 6 hours and is not dangerous)
An angiogram, or arteriogram, is a series of x-rays taken after a special dye is
injected into an artery (usually in the area where the abdomen joins the top of
the leg). The dye, which flows through the blood vessels of the brain, can be
seen on the x-rays. These x-rays can show the tumor and the blood vessels that
lead to it
A myelogram is an x-ray of the spine. A special dye is injected into the
cerebrospinal fluid in the spine, and the patient is tilted to allow the dye to
mix with the fluid. This test may be done when the doctor suspects a tumor in
the spinal cord
(return to Top)
Treatment for a brain tumor depends on a number of factors. Among these are the
type, location, and size of the tumor, as well as the patient's age and general
health. Treatment methods and schedules often vary for children and adults. A
treatment plan is developed to fit each patient's needs.
The patient's doctor may want to discuss the case with other doctors who treat
brain tumors. Also, the patient may want to talk with the doctor about taking
part in a research study of new treatment methods. Such studies are called
clinical trials.
Many patients want to learn all they can about their disease and their treatment
choices so they can take an active part in decisions about their medical care. A
person with a brain tumor will have many questions, and the doctor is the best
person to answer them. Most patients want to know what kind of tumor they have,
how it can be treated, how effective the treatment is likely to be, and how much
it is likely to cost.
Many people find it helpful to make a list of their questions before they see
the doctor. Taking notes can make it easier to remember what the doctor says.
Some patients also find that it helps to have a family member or friend with
them when they talk with the doctor,either to take part in the discussion or
just to listen.
Patients and their families have a lot to learn about brain tumors and their
treatment. They should not feel that they need to understand everything the
first time they hear it. They will have other chances to ask the doctor to
explain things that are not clear.
(return to Top)
Brain tumors are treated with surgery, radiation therapy, and chemotherapy.
Depending on the patient's needs, several methods may be used. The patient may
be referred to doctors who specialize in different kinds of treatment and work
together as a team. This medical team often includes a neurosurgeon, a medical
oncologist, a radiation oncologist, a nurse, a dietitian, and a social worker.
The patient also might work with a physical therapist, an occupational
therapist, and a speech therapist.
Before treatment begins, most patients are given steroids, which are drugs that
relieve swelling (edema). They also may be given anticonvulsant medicine to
prevent or control seizures. If hydrocephalus (a condition which results in
fluid accumulation around the brain) is present, the patient may need a shunt to
drain the cerebrospinal fluid. A shunt is a long, thin tube placed in a
ventricle of the brain and then threaded under the skin to another part of the
body, usually the abdomen. It works like a drainpipe: excess fluid is carried
away from the brain and is absorbed in the abdomen. (In some cases, the fluid is
drained into the heart).
Surgery is the usual treatment for most brain tumors. To remove a brain tumor, a
neurosurgeon makes an opening in the skull. This operation is called a
craniotomy.
Whenever possible, the surgeon attempts to remove the entire tumor. However, if
the tumor cannot be completely removed without damaging vital brain tissue, the
doctor removes as much of the tumor as possible. Partial removal helps to
relieve symptoms by reducing pressure on the brain and reduces the amount of
tumor to be treated by radiation therapy or chemotherapy.
Some tumors cannot be removed. In such cases, the doctor may do only a biopsy. A
small piece of the tumor is removed so that a pathologist can examine it under a
microscope to determine the type of cells it contains. This helps the doctor
decide which treatment to use.
Sometimes, a biopsy is done with a needle. Doctors use a special head frame
(like a halo) and CT scans or MRI to pinpoint the exact location of the tumor.
The surgeon makes a small hole in the skull and then guides a needle to the
tumor. (Using this technique to do a biopsy or for treatment is called
stereotaxis).
Radiation therapy (also called radiotherapy) is the use of high-powered rays to
damage cancer cells and stop them from growing. It is often used to destroy
tumor tissue that cannot be removed with surgery or to kill cancer cells that
may remain after surgery. Radiation therapy is also used when surgery is not
possible.
Radiation therapy may be given in two ways. External radiation comes from a
large machine. Generally, external radiation treatments are given 5 days a week
for several weeks. The treatment schedule depends on the type and size of the
tumor and the age of the patient. Giving the total dose of radiation over an
extended period helps to protect healthy tissue in the area of the tumor.
Radiation can also come from radioactive materials placed directly in the tumor
(implant radiation therapy). Depending on the material used, the implant may be
left in the brain for a short time or permanently. Implants lose a little
radioactivity each day. The patient stays in the hospital for several days while
the radiation is most active.
External radiation may be directed just to the tumor and the tissue close to it
or, less often, to the entire brain (sometimes the radiation is also directed to
the spinal cord). When the whole brain is treated, the patient often receives an
extra dose of radiation to the area of the tumor. This boost can come from
external radiation or from an implant.
Stereotactic radiosurgery is another way to treat brain tumors. Treatment is
given in just one session; high- energy rays are aimed at the tumor from many
angles. In this way, a high dose of radiation reaches the tumor without damaging
other brain tissue. (This use of radiation therapy is sometimes called Gamma
KnifeŽ Surgery).
Chemotherapy is the use of drugs to kill cancer cells. The doctor may use just
one drug or a combination, usually giving the drugs by mouth or by injection
into a blood vessel or muscle. Intrathecal chemotherapy involves injecting the
drugs into the cerebrospinal fluid.
Chemotherapy is usually given in cycles: a treatment period followed by a
recovery period, then another treatment period, and so on. Patients often do not
need to stay in the hospital for treatment. Most drugs can be given in the
doctor's office or the outpatient clinic of a hospital. However, depending on
the drugs used, the way they are given, and the patient's general health, a
short hospital stay may be necessary.
Clinical Trials
Researchers are looking for treatment methods that are more effective against
brain tumors and have fewer side effects. When laboratory research shows that a
new method has promise, doctors use it to treat cancer patients in clinical
trials. These trials are designed to answer scientific questions and to find out
whether the new approach is both safe and effective. Patients who take part in
clinical trials make an important contribution to medical science and may have
the first chance to benefit from improved treatment methods.
Many clinical trials of new treatments for brain tumors are under way. Doctors
are studying new types and schedules of radiation therapy, new anticancer drugs,
new drug combinations, and combinations of chemotherapy and radiation.
Scientists are trying to increase the effectiveness of radiation therapy by
giving treatments twice a day instead of once. Also, they are studying drugs
called radiosensitizers. These drugs make the cancer cells more sensitive to
radiation. Another method under study is hyperthermia , in which the tumor is
heated to increase the effect of radiation therapy.
Many drugs cannot reach the brain cells because of the blood- brain barrier, a
network of blood vessels and cells that filters blood going to the brain.
Researchers continue to look for new drugs that will pass through the
blood-brain barrier. Studies are under way using different techniques to
temporarily disrupt the barrier so that drugs can reach the tumor.
In other studies, scientists are exploring new ways to give the drugs. Drugs may
be injected into an artery leading to the brain or may be put directly into the
ventricles. Doctors also are studying the effectiveness of placing tiny wafers
containing anticancer drugs directly into the tumor (the wafers dissolve over
time).
Researchers are also testing the use of very high doses of anticancer drugs.
Because these higher doses may damage healthy bone marrow, doctors combine this
treatment with bone marrow transplantation to replace the marrow that has been
destroyed.
Biological therapy is a new way of treating brain tumors that is currently under
study. This type of treatment is an attempt to improve the way the body's immune
system fights disease.
Patients interested in taking part in a clinical trials should discuss this
option with their doctor. They may want to read "What Are Clinical Trials All
About?", a National Cancer Institute (NCI) booklet that explains some of the
possible benefits and risks of treatment studies.
One way to learn about clinical trials is through PDQ, a computerized resource
of cancer treatment information. Developed by NCI, PDQ contains an up-to-date
list of trials in progress all over the country. Doctors can use a personal
computer or the services of a medical library to get PDQ information. The Cancer
Information Service, at 1-800-4-CANCER, is another source of PDQ information for
doctors, patients, and the public.
(return to Top)
Cancer treatment often causes side effects. These side effects occur because
treatment to destroy cancer cells damages some healthy cells as well.
The side effects of cancer treatment vary. They depend on the type of treatment
used and on the area being treated. Also, each person reacts differently.
Attempts are made to plan the patient's therapy to keep side effects to a
minimum. Patients are very carefully watched so that any problems which occur
can be addressed.
A craniotomy is a major operation. The surgery may damage normal brain tissue,
and edema may occur. Weakness, coordination problems, personality changes, and
difficulty in speaking and thinking can result. Patients can also have seizures.
In fact, for a short time after surgery, symptoms may be worse than before. Most
of the side effects of surgery lessen or disappear with time.
Most of the side effects of radiation therapy go away soon after treatment is
over. However, some side effects may occur or persist long after treatment is
completed.
Some patients have nausea for several hours after treatment. Patients receiving
radiation therapy may become very tired as treatment continues. Resting is
important, but doctors usually advise their patients to try to stay reasonably
active. Radiation therapy to the scalp causes most patients to lose their hair.
When it grows back, the new hair is sometimes softer and may be a slightly
different color. In some cases, hair loss is permanent.
Skin reactions in the treated area are common. The scalp and ears may be red,
itchy, or dark. These areas may look and feel sunburned. The treated area should
be exposed to the air as much as possible but should be protected from the sun.
Patients should not wear anything on the head that might cause irritation. Good
skin care is important at this time. The doctor may suggest certain kinds of
soap or ointment, and patients should not use any other lotions or creams on the
scalp without the doctor's advice.
Sometimes, brain cells killed by radiation form a mass in the brain. The mass
may look like a tumor and may cause similar symptoms, such as headaches, memory
loss, or seizures. Doctors may suggest surgery or steroids to relieve these
problems. About 4 to 8 weeks after radiation therapy, patients may become quite
sleepy or lose their appetite. These symptoms may last several weeks, but they
usually go away on their own. Still, patients should notify the doctor if they
occur.
Children who have had radiation therapy for a brain tumor may have learning
problems or partial loss of eyesight. If the pituitary gland is damaged,
children may not grow or develop normally.
The side effects of chemotherapy depend on the drugs that are given. In general,
anticancer drugs affect rapidly growing cells, such as blood cells that fight
infection, cells that line the digestive tract, and cells in the hair follicles.
As a result, patients may have a lowered resistance to infection, loss of
appetite, nausea, vomiting, or mouth sores. Patients also may have less energy
and lose their hair. These side effects usually go away gradually after
treatment stops.
Some anticancer drugs can cause infertility. Women taking certain anticancer
drugs may have symptoms of menopause (hot flashes and vaginal dryness; periods
may be irregular or stop). Some drugs used to treat children and teenagers may
affect their ability to have children later in life.
Certain drugs used in the treatment of brain tumors can cause kidney damage.
Patients are given large amounts of fluid while taking these drugs. Patients
also may have tingling in the fingers, ringing in the ears, or difficulty
hearing. These problems may not clear up after treatment stops.
Treatment with steroids to reduce swelling in the brain can cause increased
appetite and weight gain. Swelling of the face and feet is common. Steroids can
also cause restlessness, mood swings, burning indigestion, and acne . Patients
should not stop using steroids or change their dose without consulting the
doctor. The use of steroids must be stopped gradually to allow the body
time to adjust.
Loss of appetite can be a problem for patients during therapy. People may not
feel hungry when they are uncomfortable or tired. Some of the common side
effects of cancer treatment, such as nausea and vomiting, can also make it hard
to eat. Yet, good nutrition is important because patients who eat well generally
feel better and have more energy. In addition, they may be better able to
withstand the side effects of treatment. Eating well means getting enough
calories and protein to help prevent weight loss, regain strength, and rebuild
normal tissues. Many patients find that eating several small meals and snacks
during the day works better than trying to have three large meals.
Patients being treated for a brain tumor may develop a blood clot and
inflammation in a vein, most often in the leg. This is called thrombophlebitis.
A patient who notices swelling in the leg, leg pain, or redness in the leg
should notify the doctor right away.
Doctors, nurses, and dietitians can explain the side effects of cancer treatment
and can suggest ways to deal with them.
(return to Top)
Rehabilitation is a very important part of the treatment plan. The goals of
rehabilitation depend on the patient's needs and how the tumor has affected his
or her daily activities. The medical team makes every effort to help patients
return to their normal activities as soon as possible.
Patients and their families may need to work with an occupational therapist to
overcome any difficulty in activities of daily living, such as eating, dressing,
bathing, and using the toilet. If an arm or leg is weak or paralyzed, or if a
patient has problems with balance, physical therapy may be necessary. Speech
therapy may be helpful for individuals having trouble speaking or expressing
their thoughts. Speech therapists also work with patients who are having
difficulty swallowing.
If special arrangements are necessary for school-age children, they should be
made as soon as possible. Sometimes, children have tutors in the hospital or
after they go home from the hospital. Children who have problems learning or
remembering what they learn may need tutors or special classes when they return
to school.
(return to Top)
Regular follow-up is very important after treatment for a brain tumor. The
doctor will want to check closely to be sure that the tumor has not returned.
Check-ups usually include general physical and neurologic exams. From time to
time, the patient will have CT scans or MRI.
Patients who receive radiation therapy to large areas of the brain or certain
anticancer drugs may have an increased risk of developing leukemia or a second
tumor at a later time. Also, radiation that affects the eyes may lead to the
development of cataracts . Patients should carefully follow their doctor's
advice on health care and checkups. If any unusual health problem occurs, they
should report it to the doctor as soon as it appears.
The diagnosis of a brain tumor can change the lives of patients and the people
who care about them. These changes can be hard to handle. Patients and their
families may have many different and sometimes confusing emotions.
At times, patients and those close to them may feel frightened, angry, or
depressed. These are normal reactions when people face a serious health problem.
Most patients, including children and teenagers, find it helps to share their
thoughts and feelings with loved ones. Sharing can help everyone feel more at
ease and can open the way for others to show their concern and offer their
support.
Worries about tests, treatments, hospital stays, rehabilitation, and medical
bills are common. Parents may worry about whether their children will be able to
take part in normal school or social activities. Doctors, nurses, social
workers, and other members of the health care team may be able to calm fears and
ease confusion. They also can provide information and suggest helpful resources.
Patients and their families are naturally concerned about what the future holds.
Sometimes, they use statistics to try to figure out whether the patient will be
cured or how long he or she will live. It is important to remember, however,
that statistics are averages based on large numbers of patients. They can't be
used to predict what will happen to a certain patient because no two cancer
patients are alike. The doctor who takes care of the patient and knows that
person's medical history is in the best position to discuss the patient's
outlook (prognosis).
People should feel free to ask the doctor about their prognosis, but it is
important to keep in mind that not even the doctor can tell exactly what will
happen. When doctors talk about recovering from a brain tumor, they may use the
term remission rather than cure. Even though many people recover completely,
doctors use this term because a brain tumor can recur.
(return to Top)
Living with a serious disease is not easy. Everyone involved faces many problems
and challenges. Finding the strength to cope with these difficulties is easier
when people have helpful information and support services.
The doctor can explain the disease and give advice about treatment, going back
to work or school, or other activities. If patients want to discuss concerns
about the future, family relationships, and finances, it also may help to talk
with a nurse, social worker, counselor, or a member of the clergy.
Friends and relatives who have had personal experience with cancer can be very
supportive. Also, it helps many patients to meet and talk with other people who
are facing problems like theirs. Cancer patients often get together in self-help
and support groups, where they can share what they have learned about cancer and
its treatment and about coping with the disease. In addition to groups for
adults with cancer, special support groups for children or teens with cancer or
for parents whose children have cancer are available in many cities. It is
important to keep in mind, however, that each patient is different. Treatments
and ways of dealing with cancer that work for one person may not be right for
another, even if they both have the same kind of cancer. It is a good idea to
discuss the advice of friends and family members with the doctor.
Often, a social worker at the hospital or clinic can suggest local and national
groups that will help with rehabilitation, emotional support, financial aid,
transportation, or home care. The American Cancer Society is one such group.
This nonprofit organization has many services for patients and their families.
The American Brain Tumor Association is another organization that can help
patients find support groups in local areas.
Candlelighters Childhood Cancer Foundation sponsors support groups for parents
of children with cancer. In some cities, the Foundation has special groups for
children or teens with cancer, as well.
Information about other programs and services for cancer patients and their
families is available through the Cancer Information Service. The toll-free
number is 1-800-4-CANCER.
