Thyroid cancer that comes back
Despite treatment, thyroid cancer can return, even if you've had your thyroid removed. This could happen if microscopic cancer cells spread beyond the thyroid before it's removed. Thyroid cancer recurrence can occur decades after thyroid cancer treatment.
Thyroid cancer most often recurs in:
- Lymph nodes in the neck
- Small pieces of thyroid tissue left behind during surgery
- Other areas of the body — most often the lungs or the bones
Thyroid cancer that recurs can be treated. Your doctor may recommend periodic blood tests or thyroid scans to check for signs of a thyroid cancer recurrence.
