The cause of most adult brain tumors is unknown. There are few known risk factors for brain tumors, however, the following conditions may increase the risk of developing certain types of brain tumors:
- Being exposed to vinyl chloride may increase the risk of glioma.
- Past treatment with radiation therapy to the scalp or brain may increase the risk of meningioma.
- Infection with the Epstein-Barr virus, having AIDS (Acquired Immunodeficiency Syndrome), or receiving an organ transplant may increase the risk of primary CNS lymphoma.
Having certain genetic syndromes may increase the risk of developing the following types of brain tumors:
