Tiamaria, I also had thyroid probelms right after my first ORAL CANCER in 1989. It turned out not to be CANCER of the thyroid, however the radiation ended up destroying it. I had to have half of it removed for it was so enlarged it was cutting of my air way. I was told way back in 1989 that it would be better for me if the CANCER was in the thyroid for they can just take the whole thing out and you can take pills to take care of all the things that the thyroid does do for the body, and believe me it does a lot. I am now on synthroid for the rest of my life. I have had hardly any real probelms with all of that...LOOKING back I wish it had of been thyroid CANCER instead of TONGUE. At least maybe I could talk and eat today...WHO KNOWS? I will pray for you that the news will be good...Always Miss Vicki
