Does radioactive iodine therapy treat thyroid cancer?

Short answer
Radioactive iodine therapy can treat some thyroid cancers when the cancer cells absorb iodine, but it is not suitable for every type.
This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.
At a glance
- How it works
- Iodine-absorbing cells receive targeted radiation
- Route
- Taken by mouth
What this means
The treatment uses radioactive iodine taken by mouth. Thyroid cells, including some thyroid cancer cells, can collect iodine; the radiation then damages those cells. It is often considered after thyroid surgery or for cancer that remains or has spread, when testing shows iodine uptake is likely.
Preparation may include changing thyroid hormone medicine or following dietary instructions. The team will give radiation-safety guidance because the body releases radiation for a period after treatment.
What to do next
Ask your thyroid cancer team whether your tumour type and scan findings support radioactive iodine. Discuss pregnancy, breastfeeding, medicines, dental care, isolation arrangements and how thyroid hormone replacement will be managed. Follow the written safety instructions closely.
When to seek care
Contact the treatment team for marked neck swelling, trouble breathing or swallowing, severe vomiting, dehydration or a high fever. Report persistent dry mouth, painful swelling near the jaw or changes in taste at follow-up.
Questions for your doctor
Does my cancer absorb iodine? Is treatment intended after surgery or for disease elsewhere? How should I prepare, and how long will safety precautions apply? What follow-up tests will check the response?
Questions people ask
Does radioactive iodine treat every thyroid cancer?
No. It works only when the relevant cancer cells can absorb iodine, so tumour type and test results guide the decision.
Will I need thyroid medicine afterward?
Many people need thyroid hormone replacement after thyroid surgery; your team will adjust it and explain follow-up.
