Stereotactic radiosurgery (SRS) for small brain tumors is a non-invasive treatment that precisely delivers high doses of radiation to small tumors in the brain. Despite its name, it doesn't involve actual surgery. Instead, it uses advanced imaging to precisely locate the tumor's position and shape. Then, using highly focused radiation beams from various angles, it targets the tumor while sparing surrounding healthy tissue. This treatment is effective for small tumors or those in delicate areas where traditional surgery is risky. It aims to destroy or shrink the tumor, offering a less invasive alternative to surgery.
