My ex-husband had thyroid cancer with lymph nodes involved..  His surgery took 5 1/2 hours and he has an incision from ear to ear.  He told me he has  a 50% chance of survival.  I am concerned he is not telling me the total truth.  Do you have any ideas as to where it might return if it does.?
There are 3 types of thyroid cancer. Differentiated, undifferentiated and medullary thyroid cancer. You have not mentioned stage of thyroid cancer after operation. If it is well differentiated, and it is not spread to any other parts, there is good prognosis. Even if it is spread, radio iodine can be given that will prolong the life. If it is undifferentiated, prognosis is poor
