MEDICAL ANIMATION TRANSCRIPT: Your doctor may also want to give you radiation therapy. This therapy uses radiation to kill the cancer cells or keep them from growing. External beam radiation uses a machine outside the body that aims radiation at the cancer. Internal radiation therapy, also known as brachytherapy, uses a substance that gives off radiation through different types of delivery devices. The substance is put inside your breast where the cancer has been removed.
