CyberKnife uses beams of high-dose radiation to treat cancerous and benign tumors anywhere on the body, according to Accuray, the maker of CyberKnife. It can treat tumors in areas such as the head, spine, liver, lungs, prostate, ovaries and pancreas.
CyberKnife is an FDA-approved, noninvasive, pain-free option that is ideal for treating tumors that are complex or inoperable, explains Accuray. CyberKnife delivers high doses of radiation with extreme accuracy. There is no need for an incision, anesthesia or hospitalization. Because it targets the tumor so precisely, surrounding tissues receive minimal damage, and clinicians complete treatment within one to five days rather than the weeks that regular radiation treatments require. Patients treated with CyberKnife need little or no recovery time and can resume daily activities immediately. Depending on the treatment site, some patients may experience side effects such as nausea or mild fatigue.
CyberKnife is the brand name of a stereotactic radiosurgery device that uses imaging technology and computer guidance systems to deliver precise beams of radiation, explains Memorial Sloan Kettering Cancer Center. A distinguishing feature of the CyberKnife is the robotic arm that it employs to deliver the radiation beam. The skill and experience of the clinicians directing the radiation beam are key.
