Why is radioactive iodine used in thyroid cancer?
This way, when you take the capsule (or drink the liquid) it will all be taken up into the thyroid gland and the effect of the beta radiation will be mostly confined to the thyroid tissue, which is the target of the treatment. The point of the radio-iodine treatment is to destroy the thyroid tissue which is causing the over-production of thyroid hormones. This is especially important for patients with certain types of thyroid cancer who need to have all thyroid cells within their body destroyed in order to cure the cancer and to stop it from spreading. So, yes, radiation can be dangerous when not carefully controlled, but that very fact is the reason why the treatment works. The aim of the treatment is to damage and kill the cells responsible for the hyperthyroidism. Radioactive iodine and some other radioisotopes used in Nuclear Medicine are produced during the production of nuclear energy. They are a by-product or, if you like, a useful waste product. Every batch is rigorously tested to ensure its safety.

Mechanism of action
- The mechanism of how RAI Treatment works to treat thyroid cancer was not discovered until years following its use to treat papillary thyroid cancers. We now know today that papillary thyroid cancers can possess a type of key hole on the surface of their cell called a symporter that allows iodine to be taken into the cell. Under normal circumstances, iodine is taken up by normal thyroi…
