stereotactic radiosurgery


<b>steer</b>-e-o-<b>TACK</b>-tick <b>ray</b>-dee-o-<b>SUR</b>-jer-ee


a treatment method that focuses high doses of radiation at a tumor while limiting the exposure that normal tissue receives. Though it is called surgery, no knife or scalpel is used. The treatment may be useful for tumors that are in places where regular surgery would harm essential tissue, for example, in the brain or spinal cord, or when the patient’s condition does not permit regular surgery. See also radiation, spinal cord.
