Radiation Therapy

Radiation therapy uses high-energy rays or particles to kill cancer cells. Radiation is sometimes used as the initial treatment for low-grade cancer that is still confined within the prostate gland or that has only spread to nearby tissue. Cure rates for men with these types of cancers are much like those for men getting radical prostatectomy. Radiation is also sometimes used if the cancer is not completely removed or comes back (recurs) in the area of the prostate after surgery. If the disease is more advanced, radiation may be used to reduce the size of the tumor and to provide relief from present and possible future symptoms.

Two main types of radiation therapy are used: external beam radiation and brachytherapy (internal radiation). Both appear to be good methods of treating prostate cancer, although there is more long-term information about the results of treatment with external beam radiation.
