Re: Thyroid Regrowth?????
Hi! I had papillary last year, so I don't know as much as you. But, I think that thyroid tissue can regrow, and that's why they do the RAI to ablate all remaining tissue, and then keep your TSH suppressed, because if your body needs Thyroid hormone, your body just may create it, and if your TSH is suppressed, it hopefully doesn't grow back because your body has all it needs and then some.
So I would think that the regrowth would be considered a "recurrence" (any thyroid tissue is considered a "recurrence" healthy or cancerous is a danger to become cancerous)----is your endo now sending you for scans? You might have to do that to see where it is and what they should destroy?
Also----was your TSH maintained at a suppressed level all along? Were you "hypo" when the thyroglobulin was done? Just curious.
Hopefully, your endo knows what to do next.......my best wishes to you, ---if the doctor isn't worked up about it, that's always a good sign
