If cancer has spread far from your prostate, your health care provider may suggest radiation. Prostate cancer often spreads to the bones. Radiation can help ease pain caused by cancer spreading to the bone. It can ease other symptoms.
The radiation is most often given in one or a few visits. The treatment is like having an x-ray. It uses high-energy beams to kill tumors. New radiation techniques focus on cancer cells while saving nearby healthy tissue. Many use computers to map the prostate. They target radiation just where it is needed. New software allows better planning and targeting of radiation doses.
These methods are expected to improve the success of radiation therapy. And they reduce side effects. Studies are being done to find out which radiation methods are best for which men.
