Stereotactic Gamma Ray Surgery for Benign Intracranial Tumors

Medically reviewed by Last updated on Dec 2, 2022.

This surgery is used to treat benign (not cancer) tumors inside your head. Beams of radiation kill the tumor cells. Normal tissues near the tumor get little or no radiation. Tumors can grow anywhere in your head. Benign tumor cells do not spread to other areas of your body.
