The CyberKnife System offers a non-surgical, non-invasive treatment option that delivers proven results for a wide range of cancers and metastases. CyberKnife provides stereotactic body radiation therapy (SBRT) and stereotactic radiosurgery (SRS), closely related types of radiation therapy that involve delivering a relatively higher dose of radiation with extreme accuracy. The high level of precision of this approach — also called hypofractionation — enables a higher dose of radiation to be delivered to a tumor in significantly fewer treatment sessions, while also reducing the radiation exposure to surrounding healthy tissues.
