what is the cause of brain tumer ?

Answer 1

Doctors generally divide brain tumors into the following categories to explain where or how they originate:

Primary. Primary brain tumors originate in the brain or close to it, such as in the skull, brain membranes (meninges), cranial nerves, pituitary gland or pineal gland. Most brain tumors in children are primary. Slightly more than one-fourth of all brain tumors are primary. The remaining are secondary (metastatic). It's not known what causes primary brain tumors. It's possible that heredity, environmental factors, viruses or other factors play a role in their development.

Some common types of primary tumors — named after the type of brain cells from which they originate — include acoustic neuromas (schwannomas), astrocytomas, medulloblastomas, meningiomas and oligodendrogliomas.

Secondary. Secondary (metastatic) brain tumors are tumors that result from cancer that starts elsewhere in your body and then spreads (metastasizes) to your brain. Cancers of the lung and breast are most likely to spread to your brain. Sometimes, a brain tumor is the first sign of cancer that began elsewhere in your body.
