Types of Radiation Treatments

Different types of radiation treatments are used to treat cancer. Some treatments deliver the radiation from outside the body, and others deliver the radiation internally. The type of radiation used is based on different factors, including the type, size and stage of the cancer, as well as the patient’s general health, making sure they are strong enough to undergo the series of treatments.

When treatments are delivered from outside the body, it is called external radiation therapy. It is considered local treatment because it only treats the specific part of your body where the cancer is located.

When treatments are delivered internally, it is called internal beam radiation therapy.

Your cancer care team will determine the best treatment for your cancer based on the American Society of Radiation Oncology’s (ASTRO) established guidelines for treatment.
