Radioactive Iodine


Treatment with radioactive iodine can help reduce the risk of thyroid cancer coming back. It may also be used to treat thyroid cancer that may have spread to other parts of the body. This very effective treatment is possible because the iodine will enter the thyroid cells from your blood stream. The radioactivity destroys the cancer cells. Radioactive iodine is usually only given once. Radioactive iodine is given in tablet form.

You can expect to be in hospital for about 3 to 6 days; depending on how quickly the radioactivity leaves your body. When the radioactivity goes below a certain level you will be allowed home.

Please contact your consultant or the Department of nuclear medicine should you require further information.
