The “Incisionless” Knife that Transformed
Brain Tumor Care

Imagine a knife that involves no cuts and causes no pain, but can reach tumors located in the deepest recesses of the brain. It’s called the Gamma Knife®, and it’s been at John Theurer Cancer Center since 2012. This form of stereotactic radiosurgery (SRS) makes it possible for doctors to treat brain tumors considered inaccessible or inoperable by conventional surgery. Moreover, no hospital stay is required. You can go home the same day as your treatment.

Surgery With Safety

Gamma Knife is not a knife at all, but a treatment that brings together multiple radiation beams from different angles with pinpoint precision to destroy a tumor. Individually, each beam is weak, but together they pack a powerful punch—without damaging surrounding healthy tissue.  Your treatment team, including your radiation oncologist and neurosurgeon, uses imaging tests to customize your treatment to the size, shape, and type of your tumor, and then delivers a single, high-intensity radiation dose. You can return to your normal activities far sooner than you would with conventional surgery. Your doctors will let you know if Gamma Knife radiosurgery is an option for you.
