The CyberKnife Robotic Radiosurgery System is a non-invasive alternative to surgery for the treatment of both cancerous and non-cancerous tumors anywhere in the body, including the prostate, lung, brain, spine, liver, pancreas, and kidney. The treatment—which delivers high doses of radiation to tumors with extreme accuracy—offers new hope to patients who have inoperable or surgically complex tumors, or who may be looking for a non-surgical option. To date, more than 50,000 patients have been treated and more than 150 CyberKnife systems are installed worldwide.

Initially, radiosurgery was used to treat brain tumors; when technical improvements allowed for radiosurgery to be used anywhere in the body, the possible treatment sites were expanded to include cancer involving the spine. With more experience and further improvements in targeting tumors, the possible sites or types of cancers that may benefit have expanded dramatically.
The most common sites are noted below:
Benign Tumors
Brain
Colon
Head and Neck
Kidney
Liver
Lung
Metastases
Pancreas
Prostate
Spine
While most inoperable areas of the body can be treated with CyberKnife safely, the most common treatments are for:
Acoustic Neuroma
Arteriovenous Malformations (AVM)
Astrocytoma
Bladder Cancer
Brain Cancer – primary, multiple, and metastases can be treated in one session
Cavernous Sinus Tumors
Colon Cancer
Glioma
Head and Neck Cancer
Kidney (Renal) Cancer
Liver (Hepatocellular) Cancer – primary and metastatic
Lung Cancer – primary and metastatic
Meningioma
Osteosarcoma
Pancreatic Cancer
Parasellar Meningioma
Pituitary Adenoma
Prostate Cancer
Rectal and Anal Tumors and Cancer
Skeletal Metastases
Solitary Lymph Node
Spinal Cord and Nerves – benign and malignant tumors
Spinal Cord Tumors – Cervical, Thoracic, Lumbar, and Sacral Spine – primary and metastatic
Spinal Cord Tumors – Intradural and Intramedullary
Trigeminal Neuralgia
