The CyberKnife -- a powerful new weapon in the war on cancer -- involves no cutting, like the name implies. This robotic system instead uses hundreds of focused radiation beams to destroy a tumor. A robotic arm moves around the patient and an image-guided system tracks the targeted tumor. CyberKnife delivers small blasts of radiation from up to 200 angles and keeps the tumor in its sights at all times. CyberKnife treatments are completed in one to five days which is just one of the benefits of this therapy compared to traditional radiation therapy.

With traditional radiation, patients often endure treatment for five to eight weeks. And healthy tissue can be destroyed every time the patient shifts or breathes. The CyberKnife attacks the cancerous tumor only -- even while the patient breathes. CyberKnife therapy, available in only 50 hospitals in the United States, requires no mold to position patients, can treat anywhere in the body, and can help patients who no longer respond to traditional treatments.

CyberKnife is covered by insurance and approved by Medicare.
