What is a primary brain tumor?

Primary brain tumors originate inside the brain or its immediate surroundings. Primary brain tumors can be benign or malignant, and are usually named after the brain cells or the location from which they originate. The most common primary brain tumor is the benign meningioma, accounting for 34% of all brain tumors. It arises from the coverings or meninges of the brain and is surgically curable in the majority of cases. The second most common primary brain tumors accounting for 31%, are the gliomas, which originate within the brain's glial cells.
Common primary brain tumors include:
  • meningioma
  • astrocytomas
  • anaplastic gliomas
  • craniopharyngiomas
  • ependymomas
  • glioblastomas
