SRS and SRT How the treatments work Stereotactic Radiosurgery (SRS) is the non-invasive delivery of a precise, single dose of high-energy radiation to a tumor. Although it is called surgery, there is actually no incision and it is often performed on an outpatient basis, eliminating the complications and substantial recovery time associated with traditional surgery. Stereotactic radiotherapy (SRT) delivers radiation in small, divided doses over a number of sessions. This method of delivery limits normal tissue damage while maximizing treatment effectiveness to abnormal cells. This is particularly valuable in treating conditions where the abnormal cells are close to, or within the functionally important areas of the body such as the spinal cord, optic nerve or brain stem. Your doctors will recommend the technique best suited for you after careful consideration of the size, shape and type of tumor. How does it work? During treatment, Novalis steadily moves around the patient's body so that the radiation penetrates the tumor or lesion from different angles. While the target receives the full dose of radiation, the surrounding healthy tissue only receives a small percentage of the radiation, reducing potential damage to delicate structures such as the brainstem or spinal cord. This type of treatment is virtually painless and does not typically require anesthesia. In addition, there is no scarring, disfigurement or risk of infection.
