Like the name implies, radiation therapy uses high-powered x-rays or other forms of radiation to inhibit and kill cancer cells directly. This form of treatment is often used in conjunction with other methods to prevent breast cancer from recurring in the future. Additionally, this is an effective form of treatment for cases of breast cancer that have spread to other parts of the body. Radiation can be administered internally through an implant, but more commonly, this procedure is done externally with a machine that can direct beams at the affected area. It's common for patients to experience some side effects with radiation therapy, but these are generally limited to the areas of the body where radiation is administered.
