Radioactive iodine therapy

Radioactive iodine therapy is a form of radiotherapy that is used primarily in the treatment of thyroid cancer. It involves the administration of a radioactive isotope of iodine, known as Iodine-131, which is absorbed by the thyroid gland and destroys the cancer cells.

History

The use of radioactive iodine in medicine dates back to the 1940s, when it was first used to treat hyperthyroidism. The success of this treatment led to its application in the treatment of thyroid cancer.

Procedure

The procedure for radioactive iodine therapy typically involves the oral administration of a capsule or liquid containing Iodine-131. The radioactive iodine is then absorbed by the thyroid gland, where it emits beta particles that destroy the cancer cells. The amount of radioactive iodine given will depend on the size and type of the thyroid cancer being treated.

Side Effects

Like all forms of radiotherapy, radioactive iodine therapy can have side effects. These can include nausea, dry mouth, and changes in taste. In rare cases, it can also lead to a decrease in the production of blood cells in the bone marrow.

Effectiveness

Radioactive iodine therapy is considered to be a highly effective treatment for thyroid cancer, particularly for cancers that have not spread beyond the thyroid gland. It is also used in cases where the cancer has recurred after surgery.
