The Edge Difference

The Edge® radiosurgery system from Varian Medical Systems offers a new line of defense in the fight against cancer. Using advanced cancer treatment technology, the Edge® system offers patients a fast, effective surgical option for treating tumors without incisions or the need for overnight hospital stays. It may be used to treat tumors found in the lung, prostate, brain, spine and other areas throughout the body. The Edge Radiosurgery system uses a real-time tumor tracking system so clinicians can detect slight tumor movement, thus potentially minimizing the radiation dose to surrounding healthy tissue.
