> Thyroid cancer treatment depends on type and stage — surgery, radioactive iodine, hormone suppression, and targeted therapy. Overview of options.

Thyroid cancer treatment is highly individualised — it depends on cancer type, size, spread, and patient factors. This page provides a general overview of the options.
Specific treatment plans require specialist evaluation.

## Surgery — the foundation

Surgery is the primary treatment for most thyroid cancers. Lobectomy may suffice for small, low-risk papillary cancers; total thyroidectomy is standard for larger, higher-risk, or medullary cancers. Lymph node dissection is added when nodes are involved.
Experienced thyroid surgeons minimise risks to voice nerves and parathyroid glands.

## Radioactive iodine

For differentiated thyroid cancers (papillary, follicular), radioactive iodine destroys residual thyroid tissue and micrometastases. It is used selectively — not all patients need it — based on risk stratification.
Before RAI, patients may need thyroid hormone withdrawal or recombinant TSH to stimulate any remaining tissue to take up iodine.

## Hormone therapy and suppression

After total thyroidectomy, lifelong levothyroxine replaces hormone. For differentiated cancers, the dose is often deliberately higher initially to suppress TSH — reducing stimulation of residual cancer cells.
TSH targets are individualised by risk level — higher-risk patients get more suppression.

## Advanced and targeted therapies

For recurrent or metastatic disease, external beam radiotherapy, chemotherapy, and targeted therapies (tyrosine kinase inhibitors, BRAF inhibitors) are options. Medullary cancer may respond to RET inhibitors; anaplastic cancer to BRAF-directed and immunotherapy approaches.
Clinical trials offer access to newer treatments for advanced disease.

## Frequently asked questions

### Do all thyroid cancers need radioactive iodine?

No — low-risk papillary cancers confined to the thyroid may be cured by surgery alone. RAI is reserved for higher-risk features.

### What is TSH suppression?

Keeping TSH below normal range reduces stimulation of residual thyroid tissue — standard for higher-risk differentiated cancers. It requires monitoring for over-replacement effects.

### What is the prognosis?

Differentiated thyroid cancers have excellent long-term survival. Medullary and anaplastic cancers have more variable outcomes depending on stage — early specialist care improves results.
