Survivors of thyroid cancer can be affected by a number of health problems, but often their greatest concern is facing another cancer. Cancer that comes back after treatment it is called a recurrence. But some cancer survivors may develop a new, unrelated cancer later. This is called a second cancer.
Unfortunately, being treated for cancer doesn’t mean you can’t get another. People who have had thyroid cancer can still get the same types of cancers that other people get. In fact, they might be as risk for certain types of cancer.
People who have or had thyroid cancer can get any type of second cancer, but they have an increased risk of developing:
Adrenal cancer risk is especially high in people who had the medullary type of thyroid cancer.

Patients who have completed treatment should keep up with early detection (screening) tests for other types of cancer.
