Gamma Knife radiosurgery destroys a brain tumor by zapping it with 192 intersecting gamma ray beams. That’s the idea behind the Leksell Gamma Knife® Icon™, a minimally invasive treatment used mostly to treat benign tumors and malignant metastatic tumors, which have spread to the brain from other parts of the body.
The Gamma Knife unit is also used to treat other noncancerous brain conditions, including trigeminal neuralgia and arteriovenous malformations. In some cases, Gamma Knife makes it possible to treat deeply embedded tumors that cannot be reached with conventional surgery.
Gamma Knife radiosurgery is done as an outpatient procedure, often in a single day, and does not require general anesthesia. Treatment is delivered with no incisions, painlessly, silently, and with extreme precision. Roswell Park is the only Western New York institution equipped with a Gamma Knife. In 2018, Roswell Park treated the highest number of patients in the U.S. for a single Gamma Knife device (540).
All of Roswell Park’s board-certified neurosurgeons are trained to perform both traditional “open” surgery and Gamma Knife radiosurgery.
