Tens of millions of nuclear medicine procedures are performed each year, and demand for radioisotopes is increasing rapidly.
Sterilization of medical equipment is also an important use of radioisotopes.
Radioisotope therapy brings radiation directly into the cancer cells. Normally you are supposed to be given the radioisotope or radionuclide (a radioactive nuclide) usually as a capsule, drink or injection directly into a vein. Your cancer cells absorb the radioactive substance more than normal cells. This means they receive a higher Quantity of radiation, causing them to die!
There are a lot of different types of radioisotope treatments depending on what type of cancer you have!
There is:
Iodine-131 is used to treat certain types of thyroid cancer and some other rarer types of cancer. You may need to stay in hospital for this treatment.
