A Meningioma is a specific type of brain tumor growing in the lining of the skull that protects the brain. These tumors are mostly benign, but about 10% are cancerous. Benign meningiomas don’t spread to the rest of the body, while the cancerous type can spread.
A genetic disorder known as neurofibromatosis 2 is the cause of many cases. Radiation exposure, skull fractures, and damage to the lining of the brain also seem to be risk factors for this condition.
These tumors grow slowly, so most of the time they don’t cause symptoms until they’re pressing on a nerve or part of the brain.
Seizures can also indicate the presence of one of these tumors in the brain.
Since nearly 40% of brain tumors in adults are meningiomas, there are many well-tested treatments to deal with the tumors when they interfere with your health. Tumors that aren’t growing or causing problems that test as benign tend to be left in place and monitored.
Radiation is the best option for tumors that are too delicate to remove or that aren’t responding to surgery. In aggressive forms of this brain cancer, secondary chemotherapy and extra surgery is used to eliminate any cancer that spread to the lungs or other organs. If the tumors return after removal, they’re usually treated with radiation even when they’re benign.
