thank you for your comments
I had TT with neck disection and got along fine. The surgeon dug down to my breast bone removing lymph nodes and there were 5 large growths on my thyroid, the largest being 4.8cm. Two parathyroids were removed which sometimes happens, and the remaining two have not resumed working. I had a paralyzed vocal cord for 6 weeks after surgery. The surgeons have to tell you of all the possibilities, but they likely won't be encountered. Good luck.
