Stereotactic radiosurgery (SRS) refers to a single or several steretactic radiation therapy treatments of the brain or the spine. It is a specialized technique that allows your radiation oncologist to use extremely focused beams of radiation to destroy certain types of tumors using higher doses than with daily radiation treatments. Since the beam is so precise, your radiation oncologist may be able to spare more healthy tissue. In selected cases, stereotactic treatments can be used to retreat tumors that have received radiation before.
In addition to treating some cancers or benign tumors, radiosurgery can also be used to treat malformations in the brain’s blood vessels and certain noncancerous (benign) neurologic conditions. In some cases, using more than a single dose may help decrease the risk of side effects with stereotactic radiation therapy.
