Gamma Knife® treatment for brain tumors

Gamma Knife technology provides a noninvasive treatment option for some patients diagnosed with brain tumors. Gamma Knife treatment damages the tumor’s cells in a way that inhibits their ability to reproduce. The tumor’s cells eventually die, and the tumor may gradually shrink. Gamma Knife may provide an option for some patients whose tumors have been previously considered inoperable. It can also be a part of a treatment plan that includes other surgeries or medical therapies.

What are the side effects of Gamma Knife treatment for brain tumors?

Following treatment, some patients experience mild side effects including fatigue, headache or nausea. These side effects usually clear up in one or two days.
