A form of radiation therapy, stereotactic radiosurgery (SRS) uses high-power energy to treat small spinal cord and brain tumors. Unlike regular radiation, which cannot differentiate between healthy cells and tumor cells, SRS allows for precisely focused x-ray beams to be delivered in a localized area, thus minimizing damage to healthy cells. SRS does not involve any incisions or cuts to the body and does not require anesthesia.
There are two types of SRS, gamma knife and LINAC. Gamma knife SRS brings together experts from radiation oncology, neurosurgery, and medical physics to pinpoint the size, shape, and location of the area to be treated through the use of computer software and imaging scans. LINAC uses a linear accelerator to focus radiation in both the brain and other areas in the body. The system rotates around the body during treatment to better minimize damage to healthy tissue.
Often used for patients at high risk for surgery, SRS can take anywhere from 15 minutes to two hours, allowing most patients to return home the same day. Patients who find such procedures unnerving may take relaxing medications before the treatment starts. Side effects of SRS include brain swelling, vomiting, headaches, nausea, and dizziness.
