​​​Radiation therapy (also called therapeutic radiology or radiation oncology) uses X-rays, gamma rays, and charged particles to fight cancer. Like surgery, radiation therapy is used in several ways depending on the type and location of the cancer.

Certain levels of radiation work to destroy cancer cells or prevent cells from growing or reproducing. This treatment may provide a cure for cancer, control the disease, or help relieve its symptoms.

Process for Radiation Therapy

After a physical exam and a review of your medical history, your treatment team maps out the position you will be in for each treatment and the exact location on your body (referred to as treatment field or port) where the radiation will be given. Sometimes, the area on your body that requires treatment will be marked to make sure radiation is given properly. The treatment team may also make molds, headrests, or other devices that help to position you during your treatment. Imaging studies, such as CT scans, MRI scans, or PET scans, may also be performed during the simulation process to help plan how to direct the radiation during your treatments.

Once the simulation process is completed, your radiation oncologist with help from a physicist and dosimetrist, will determine your treatment plan, including the type of machine to use, the amount (dose) of radiation that is needed, and the number of treatments that will be given.

Types of Radiation Therapies

Radiation therapy is given through different methods, depending on the type of cancer, the location of the cancer and your health. Sometimes, radiation therapy is used in combination with other treatments.
