“Well look at you, two hours ago you had a malignant brain tumor, now you have none and there is no difference from looking at you!” And it was true – the treatment was as benign as drinking a glass of cool water.”

Gamma Knife Explained
Who We Are

San Diego Gamma Knife Center began as a Center of Excellence on the campus of Scripps Memorial Hospital La Jolla in 1994. San Diego Gamma Knife Center is part of the neurosciences services of Scripps Health and the only Gamma Knife radiosurgery facility in San Diego County. The Center has treated more than 4,000 patients with various brain disorders.

Brain tumors may be treated with radiosurgery (Gamma Knife),  surgery, whole brain radiation therapy, and chemotherapy. Depending on the patient’s needs, a combination of methods may be used. Patients may be referred to doctors who specialize in different kinds of treatment and work together as a team.


Gamma Knife radiosurgery is usually a one-time therapy completed in a single day. Most patients can return to activity after 24 hours.

The procedure may take less than an hour to about four hours, depending on the size and shape of the target. During the procedure:

  • You won’t feel the radiation
  • You won’t hear any noise from the machine
  • You’ll be able to talk with the doctors via a microphone
  • You can listen to music during the treatment

Gamma Knife radiosurgery is  an outpatient procedure, but the entire process can take most of a day. You may be advised to have a family member or friend who can be with you during the day and who can take you home.
