What is the prognosis of thyroid cancer?

Overall, the prognosis of thyroid cancer is very good, especially for patients younger than 40 years of age and those with small tumors. Most of these patients can be cured. Even those patients who are unable to be cured of their thyroid cancer can live a long time and feel well despite their cancer. Finally, new treatments are becoming available on a regular basis for the rare patient in whom surgery and radioactive iodine cannot destroy all of the cancer cells.
