Radiation therapy uses targeted energy, similar to X-rays, to kill cancer cells, shrink tumors and provide relief of certain cancer-related symptoms. Radiation may be used instead of surgery in men with early-stage prostate cancer that has not spread to other parts of the body. It may also be used in combination with surgery to ensure that all cancerous tissue has been removed.
At Cancer Treatment Centers of America (CTCA), our radiation oncologists use a variety of therapies and tools to deliver maximum radiation doses to tumors, with less damage to healthy tissues and organs. Focusing the radiation directly on the tumor may lower the risk of side effects. Our range of radiation therapy options includes external beam radiation therapy, stereotactic body radiation therapy, high-dose rate brachytherapy and low-dose rate brachytherapy.
