Radiation therapy is a type of cancer treatment that uses high- energy rays to kill cancer cells. There are a lot of cancers that can be treated with radiation, but a common type is prostate cancer. Prostate cancer is the most common type of cancer diagnosed in men. The types of radiation therapy used to treat prostate cancer are external beam radiation, brachytherapy, and radiopharmaceuticals. The most common machine used for radiation treatment is the linear accelerator. Most patients are treated using the linear accelerator but a select few can be treated using the cyber knife. The cyber knife is a machine that uses external beam radiation that can treat prostate cancer in qualified patients. Some of the benefits of the cyber knife treatment could be fewer side effects, less radiation to normal tissue and increased accuracy of treatment area compared to traditional radiation treatment. The patients who do not qualify for the cyber knife treatment will be treated using the linear accelerator which will be just as effective.
