Stereotactic Radiosurgery (SRS) and Stereotactic Radiotherapy (SRT) use exceptionally precise, focused radiation beams to treat tumors and other abnormal growths. Computers create 3D images that guide radiation oncologists in aiming radiation from many sources at the target area. The technology allows high doses of radiation to be delivered to the tumor with minimal exposure to surrounding healthy tissue, affording patients the benefit of surgical precision without the surgery. Tumor type, location and size will dictate whether SRS or SRT is the appropriate treatment.
SRS/SRT has proven to be a promising new technology for patients with tumors in hard-to-treat areas, such as the brain, spine, liver and lung. It yields higher cure rates for select cancers and provides a treatment when surgery is not an option.
SRS/SRT is an outpatient procedure, meaning no hospital stay, unless the patient is having other health problems that require hospitalization. SRS is a one-time treatment and SRT is delivered over two to five days. With each treatment, the patient can return home the same day and usually resume pretreatment activities.
SRS/SRT saves money and time. With no hospital stays and fewer complications, the patient experiences minimal disruptions in their life and work, which can make this procedure more cost-effective than conventional surgery.
