How is radiation therapy given to treat cancer?

Radiation (also called radiotherapy, x-ray therapy, or irradiation) for cancer treatment is administered at a hospital or treatment center in internal or external forms. Internal radiation requires a radioactive substance sealed in a container to be implanted into a tumor or body cavity. Sometimes an unsealed source is used and is taken orally or by injection. External radiation requires a machine that will direct high-energy rays at the tumor and surrounding area.
