Discussions that mention synthroid

Thyroid Disorders board

Hi, I had partial thyroidectomy in 1999 and small (less than 1 cm) papillary cancer was detected. Had other side taken out October 2007 and another small cancer was found. Am on 150mg Synthroid. In October my doctor wants to do total body scan. Never had a scan because it was deemed not necessary after surgeries. My question is: do I have to go off the Synthroid for 6 weeks or can I do the Thyrogen shots? Is it just doctor's, hospital or insurance preference's or are there certain criteria? Please help me ask the right questions.:confused:
