Radiation Oncology

Radiation oncology uses high-energy X-rays or other types of radiation to kill cancer cells. It only affects cells in the area that is being treated and is an option for men with any stage of prostate cancer.

Radiation therapy is often used as the initial treatment for low-grade cancer that has not spread outside of the prostate or that only has spread to nearby tissue. Radiation therapy also may be used after surgery to destroy any cancer cells that are still present in the area or come back (recur) after surgery. In later stages of prostate cancer, radiation treatment may be used to help relieve pain when cancer has spread to the bone.

Doctors use two types of radiation therapy to treat prostate cancer. They are external beam radiation therapy and internal radiation therapy. Some men receive both types.
