Gamma Knife and other radiosurgery procedures are referred to as “surgery without a knife” because sophisticated computer software guides subatomic particles, called gamma rays, from nearly 200 different angles to target tumors or other abnormal brain tissue. Radiosurgery involves no actual tissue cutting, and treatment is normally performed on an outpatient basis, with few, if any, side effects.

Riverside Cancer Care Center answeredRadiosurgery is a comparatively new and expanding field which offers “knifeless surgery” for some patients. The Gamma Knife uses a highly accurate beam of radiation to destroy cancer but does not involve conventional, open surgery, so it can usually be carried out in a single day. The Synergy S system is also available, offering similar treatments for tumors outside of the brain.
