What Is A Brain Tumor?

A brain tumor is an abnormal growth or mass of cells in or around the brain. It is also known as a central nervous system tumor.

Brain tumors can be nasty cancer or benign non-cancer. Some tumors multiply; others grow slowly.

Only about a third of brain tumors are malignant. However, whether cancerous or not, brain tumors can impair brain function if they grow large enough to pressure surrounding nerves, blood vessels and tissue.

Meningioma: This is the common record type of primary . Meningiomas grow slowly. They form in the meninges, the coatings of skin that protect the brain and spinal cord. In occasional cases, a meningioma can be malignant.
