Frequently asked question: What is the prognosis for differentiated thyroid cancer?

The prognosis for differentiated thyroid carcinoma is good, even if it has metastasized. The cancer may return in the place where the thyroid gland once was or in the lymph glands. That is why you must regularly go to the hospital for check-ups. A radioactive iodine uptake test will show whether the thyroid gland tissue and any metastases are gone. Your blood will also be tested for the Tg protein. The only place this protein is produced is in the thyroid gland, so you should no longer have any Tg in your blood.
