The CyberKnife is an advanced robotic technology that provides stereotactic radiosurgery and stereotactic body radiation therapy. During these procedures, precisely targeted, high-dose radiation beams are delivered to tumors throughout the body without sedation or incision while radiation exposure to healthy tissue around a tumor is minimized. CyberKnife treatment is painless and is completed in five or fewer procedures. Lung tumors, brain tumors and prostate cancer are frequently treated diseases. Most insurance plans and Medicare are accepted. St. Louis CyberKnife is a service of SSM Cancer Care at St. Clare Health Center.
