thyroid cancer

my mom needs to do radioactive iodine treatment and her numbers have to be up to 25 before they will do the treatment she is off all her thyroid medicines so her number should be going up but it goes from 7 to 13 back down to 9 why is this happening?  Should we be concerned?


This discussion is related to Wondering about TSH levels up and down...HELP.

Probably her pituitary gland is now over-compensating and trying to "kick start" her thyroid.  Has she had a TT? I am two weeks post-op, I think it takes six weeks for all the levels to fall.  You might just put a call in to the doc, but she probably has to wait it out.

She had her thyroid taken out and she had a tumor removed , so now they said she has to do the radioactive iodine scan to remove any cancer cells roaming in her body.  In order to have the scan her levels have to be at least 25 or higher to do the scan.  Shes been off her thyroid medication for 5 months her numbers should have sky rocketed by now but its back down to 9.

She may have a substantial amount of thyroid tissue left.  Have her doctors considered Thyrogen shots?
