3 weeks after my thyriod surgery my TSH level was at 31, the next week it dropped to 28 then 25 and now 18 (blood tests once per week). How is it possible for my TSH to be dropping when I have no thyroid?
I have thyroid cancer and cannot have the radioiodine scan until my TSH is at 40, but the levels are going the wrong way.

If you've had a total thyoidectomy, and it's been 6 weeks, your TSH should rise. Are you taking Cytomel in preparation for your RAI? Even though Cytomel is T3 and not T4...maybe it's causing your TSH to drop. Another possibility is a pituitary problem (pituitary tumor). Are they sure that your thyroid was cancerous and not your pituitary?
If nothing else...ask if you can have a shot of Thyrogen. That will artificially raise your TSH well over 100 in about 2 days. Usually it's reserved for those who have had at least one round of RAI "the natural way" meaning without any help of Thyrogen. But in your case..you might be the exception and you might need thyrogen.
Good luck!

while you're breastfeeding, the liklihood is very much decreased. that's continuously obtainable, yet noone can each and every be useful in this occasion devoid of a try. have you ever had a typical cycle yet? If worried, take a HPT.

Unless you are on thyroxine (synthetic thyroid medication) then this is very weird!

I don't have the faintist idea. Perhaps this is something you should ask your doctor.
