Oncologists use robots to fight cancer

CyberKnife, a non-invasive procedure that uses a robot and targeted radiation to eliminate cancerous tumors.

Last year, Jean Stuetzle, 92, learned she had lung cancer and was given 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.
