1. The most common brain tumors
are cancers from
other parts of the body (e.g. lung, breast, colon or prostate) that
spreads to the brain.
2. Primary brain tumors originate in the brain and there are over 126
such tumors listed by WHO.
3. Glioma is the commonest primary brain tumour and originates
from supporting brain cells that are called glial cells and 50% of all brain tumors begin as
benign tumors.
4. Another brain tumour called ‘Astrocytomas’
are so named because their cells look like stars ; the word ‘astro’ in
Latin means "star".
5. A primary brain tumour usually is restricted to brain and does not
spread to other organs. If brain death occurs in these patients, it
is possible to donate their organs.
6. In most instances the cause of brain tumor is not
known and they do not discriminate among gender, class or ethnicity.
7. Each year approximately 200,000 people in the United States
are diagnosed with metastatic or primary brain tumor.
8. Common symptoms of a brain tumor include headaches,
seizures, personality
changes, eye weakness, nausea or vomiting, speech disturbances, memory
loss.
9. The survival from brain tumor at five years is approximately 30%.
10. Brain tumors can be treated by surgery, radiation therapy,
stereotactic radiotherapy, chemotherapy or by using these in
combination. The most important issue when treating these patients,
besides trying to cure them, is to ensure that the quality of life is
not compromised.
