Radiation involves using high-energy rays to kill cancer cells remaining after surgery, to shrink tumors before surgery, or to relieve symptoms.
Radiation therapy may be administered externally using a machine, or internally by implanting wires, seeds, or wafers that emit radiation inside the body directly near tumors. The method of administration depends on the location and size of the tumors.
Novel radiation therapies include intra-operative radiation targeted directly at the tumor during surgery, hyperthermic radiation, and transrectal ultrasound.
