Nearby lymph nodes are sometimes removed through a separate incision in the abdomen. If the pathologist finds cancer cells in the lymph nodes, it may mean that the disease has spread to other parts of the body. Radiation therapy is another way to treat prostate cancer. In early stage prostate cancer, radiation can be used instead of surgery, or it may be used after surgery to destroy any cancer cells that may remain in the area. In advanced stages, it may be given to relieve pain or other problems.
Some patients receive both kinds of radiation therapy.
For external radiation therapy for prostate cancer, the patient is treated in an outpatient department of a hospital or clinic. Treatment generally is given 5 days a week for about 6 weeks. This schedule helps protect healthy tissues by spreading out the total dose of radiation. The rays are aimed at the pelvic area. The implant may be temporary or permanent.
