Radiosurgery is a cutting-edge, non-invasive medical procedure that uses high-dose radiation to target and destroy tumors with precision. Despite its name, radiosurgery is not a surgical procedure but a specialized form of radiation therapy.

The most well-known form of radiosurgery is stereotactic radiosurgery (SRS), which is often used to treat brain tumors or other brain abnormalities. Technologies such as Gamma Knife, CyberKnife, and linear accelerators (LINAC) are commonly employed in radiosurgery. These systems deliver radiation with sub-millimeter accuracy, allowing for precise targeting of the treatment area. Gamma Knife radiosurgery, for example, is a specialized technique used exclusively for brain treatments. It uses multiple beams of radiation from different angles to converge on the target, delivering a high dose to the abnormal tissue while sparing nearby brain structures. This technique is particularly useful for treating small or deep-seated tumors that cannot be accessed surgically.
