What is CyberKnife treatment for lung cancer?

Kenneth T. Bastin, MD
Radiation Oncology
CyberKnife radiosurgery for lung cancer is a precise, painless, non-invasive radiation treatment that can be an alternative to open surgery in certain cases. Multiple beams of high-energy radiation are delivered from multiple points outside of the body and converge precisely at the tumor or lesion inside the body. Each individual beam is not sufficient to cause harm, but the convergence of all the beams at the tumor result in the lesion receiving a very high dose of radiation while sparing nearby normal tissue.
Stereotactic body radiosurgery is a very precise way to use high-dose radiation therapy to a limited target, which may be very effective in managing lung cancer. Its advantages are the utilization of high doses of radiation to a limited target area, sparing surrounding healthy tissue.
