📖About Radioiodine Therapy
Radioiodine therapy uses a controlled oral dose of radioactive iodine-131 to destroy overactive or cancerous thyroid tissue while sparing surrounding structures, since thyroid cells uniquely absorb iodine. It is a well-established treatment for hyperthyroidism caused by Graves' disease or toxic nodules, and is also used after thyroid cancer surgery to eliminate residual tissue. The therapy avoids the need for further surgery in most cases and has decades of safety data behind it. Dosing is calculated based on gland size, uptake percentage, and the underlying condition.
