The brain is the
major organ responsible for learning, memory, thought, speech, mood and behaviour If the brain declines in function, there may be lapses in memory and
thought as well as changes in mood and behaviour. Our relationships and careers are based on learning, thought, memory, mood
and behaviour This is why when the brain becomes ill it is a life-changing
event.
Numbers
Imagine the
shock and grief of a person whose loved one suffers brain cancer! However, the
truth is that brain cancer is a worldwide problem. It is said that in the year
2002, primary malignant brain and central nervous system cancers occurred in 3.7
of 100,000 males and in 2.6 of 100,000 females worldwide. The world population
is 7,021,836,029 for mid-year 2011. There will be more victims of brain cancer.
This is why we have to be alert for early symptoms of brain cancer so that
further tests will be done and treatment will be given early.
Signs and Symptoms
Symptoms of
brain cancer usually depend on whether the brain tumour is malignant or benign.
Benign brain tumours do not contain cancer cells and once they are removed, they
usually do not go back. They also do not spread to other parts of the body.
Malignant tumours, on the other hand, contain cancer cells that grow at a rapid
rate and invade nearby healthy brain tissue or the spinal cord. Unlike other
cancers, brain cancer rarely spreads to other parts of the body. Being benign or
malignant depends on tumour grade and type of tumour. There are many types of
brain cancer. Most primary brain tumours are gliomas, meaning they arise from
glial cells.
Among adults, the most common types of brain cancer are
astrocytomas, meningiomas or oligodendroglioma. Among children, the most common
types are medulloblastomas, astrocytomas,
ependymomas and brain stem gliomas. Symptoms of
brain cancer may also depend on the size of the tumour and on the location of
the tumour. Size is important because when the tumour is big enough to press on a
nerve, symptoms are felt. Sometimes the tumour blocks flow of fluid in and out
of the brain, causing brain swelling. This also causes symptoms.
The most common
brain cancer symptoms are headaches which are usually worse during the morning.
There may also be nausea and vomiting. If there are involvements in the speech,
visual and hearing areas, there may be changes in vision, speech or hearing.
If
motor areas are involved, there may be problems in walking or balancing and
muscle jerks or twitches. Often times, there may be seizures or convulsions. In
some, there may be problems in memory and changes in mood, behaviour and
personality. There may even be numbness or tingling of extremities.
If these
symptoms are felt, it is not right to assume that you have brain cancer outright.
There may be other health problems causing these symptoms, so you should visit
your doctor to be diagnosed of the real problem behind your symptoms. There are some
people who are more likely to have an increased risk for brain cancer. People
who are constantly exposed to ionising radiation such as high-dose x-rays and
those with a family history of brain cancers can have a risk for acquiring
brain cancer too. If these symptoms occur in these patients for a long time,
then it is best to have them checked out by doctor.
