- A branch of medicine that uses small amounts of radioactive substances to make pictures of areas inside the body and to treat disease. In cancer, the radioactive substance may be used with a special machine (such as a PET scanner) to find the cancer, to see how far it has spread, or to see how well a treatment is working. Radioactive substances may also be used to treat certain types of cancer, such as thyroid cancer and lymphoma.
