Gamma Knife Program

Gamma Knife® surgery is a bloodless surgical method that is recognized worldwide as the preferred treatment for selected lesions, tumors, and conditions that afflict the body’s most important organ: the brain. The Gamma Knife Center at the Samuel Oschin Comprehensive Cancer Institute is one of only a handful of facilities in the Los Angeles area to offer Gamma Knife surgery. Radiation distorts the DNA in cancer cells. The cells then lose their ability to reproduce. Conventional radiotherapy usually involves the delivery of large volumes of radiation, which may affect normal brain tissue as well as cancer tissue. Gamma Knife technology allows radiation to only touch very small tumors or lesions deep within the brain, leaving healthy brain cells alone. This treatment is safe, accurate and effective. There is no “knife” in Gamma Knife: because no incisions are made, it avoids the risks and complications associated with traditional surgery. The treatment is performed in one day and usually does not require an overnight stay in the hospital.
