How is thyroid cancer recurrence detected? Is it possible to have a clean scan but elevated thyroglobulin?
Thyroid cancer may be considered to be recurring when it can be shown by palpation (examination by hand) or by imaging (scanning) to have recurred. However, an increase of thyroglobulin level in the blood, even when the scan is normal, would be early evidence of recurrence and could lead to other investigations, including CAT or MRI scans.
