WELCOME to the Thyroid Community .. I don't know .. sorry, but wanted to say hello. Maybe they want it a bit above .21 ... A TSH <1.0 is desirable for cancer supression and even lower #'s are better but many cannot take the side effects of a TSH like yours of 0.21 ... mine is best at 1.8 ... I was at 0.667 and had speech problems believe it or not! Word retrieval type items.

You may want to get a thyroglobulin test. If you have had a TT the presence of thyroglobulin can indicate a return of cancer. I am not familiar with Levoxyl, but I know the goal is to keep the TSH suppressed below .1, if you have had cancer.

A lot depends on whether your TSH is 21.0 or 0.21.
If your TSH was 21.0, then your meds are too high.
I'm not sure if that alone, for a few months, is enough to make the doctor worry about cancer, or if it is close enough to being a year that he wants to do a cancer check a little early, because you were not kept suppressed.
Have you been getting bloodwork every few months?
Your TSH goal is <.1 so regardless of 21 or 2.1, that is still too high. Are you being treated by an endocrinologist? If not, you should be. Yes, your thyroglobulin (Tg) level and TSH need to be monitored closely to watch for unexplained increases after being on a STABLE dose of thyroid replacement. Because your surgery was last year and RAI shortly after, you still may not be on a stable dose of meds. Usually you will need to be stabilized then monitored for about 6 months before a rise in your TSH or Tg is an indicator of recurrence.
Hope that makes sense - I've got a massive headache so *nothing* makes sense to me right now. :-)
