I've been in remission for a year and a half. I am 15 years old now. I went for my yearly checkup. My TSH is at 17. My thyroglobulin is at 4.7. I have two enlarged lymph nodes in my thyroid bed. I have thyroid tissue growing back. (No thyroid, of course). What are my chances of the thyroid cancer being back? I am about to be on my diet for the whole body scan, but the wait is killing me. I just want to know what are my chances of it being back?
