I had the same (papillary cancer, 1.5 biggest tumor, 100 mc RAI last july) and I am now only seeing an endo...I never did see an oncologist. I take blood tests every eight weeks, but now that I am level I will go three months. I am getting ready for a Thyrogen injection test in June to see if I get a thyroglobulin spike to check for recurrance. Hope that helps.
I had the same things going on. Same kind of cancer and same size tumor. My endo and oncologist argued about whether or not to do RAI. The guy who did the TT may just think he did a good job of getting it all-but the oncologist (radiation or not) will be worried about cancer spreading. With me they did the RAI-there are no side effects for most folks and you are going to be super hypo for a while anyway. In my case, they argued so long that I was already started on thyroxine, so I had to go off of it and it just lengthed my "recovery". I still have a TSH of over 60 at 7 months after TT. They had to go extra slow with me cause I had some heart issues-I hope they can bring you back to normal faster. Good Luck
I've been to both an oncologist (for possible lymphoma) and endocrinologist (for recurring papillary carcinoma and RAI). The endo is the expert for thyroid cancers - even my oncologist said he doesn't treat thyroid cancers and refers to thyroid specialist endocrinologists (most endos deal with diabetes).
Stick with the endo - they are the expert at thyroid labs.
Best to you
