The CyberKnife robot is able to move around and hit specific targets to kill the imagetumors.  The doctor states that it doesn’t work for all types of cancer, but it destroys the DNA of the cells.  If the target is defined and localized it’s a great tool but cancer is not always localized.  It can be used with other treatments such as chemotherapy. 

The treatment in the video was well handled by a 92 year old cancer patient.  El Camino Hospital in northern California was the treatment of choice for her with minimal risk.  The robot can be used from many different angles as it can move around the body.  From different angles it can shoot different types of beams. 

The device has also been used extensively for prostate cancer treatments.  BD 

Safety and Effectiveness of Using CyberKnife on Prostate Cancer

From the CyberKnife website:

“Though its name may conjure images of scalpels and surgery, the CyberKnife treatment involves no cutting. In fact, the CyberKnife System is the world’s first and only robotic radiosurgery system designed to treat tumors throughout the body non-invasively. It provides a pain-free, non-surgical option for patients who have inoperable or surgically complex tumors, or who may be looking for an alternative to surgery.”

Last year, Jean Stuetzle, 92, learned she had lung cancer and was imagegiven few options to make her well again. Then, she visited radiation oncologist Robert Sinha at El Camino Hospital in Silicon Valley. He told Jean about CyberKnife, a non-invasive procedure that uses a robot and targeted radiation to eliminate cancerous tumors. SmartPlanet looks at the new technology and how it's working on cancer patients like Stuetzle.


  1. CyberKnife is unique in that it utilizes a small particle accelerator to produce radiation and a robotic arm that precisely directs the radiation toward any body part. A feature known as RoboCouch allows for better positioning of the patient during treatment. It is more accurate and reliable than other radiotherapy systems.
