have had medullary thyroid cancer, don't give up. live each day and be thankful you have it. did you work near radiation or do have have native amer. blood? i am part native amer. and worked at nuclear plant. my body absorbed the radiation, of course that has to be proven. do you have children. i have two grown ones and two grandchildren. you are right when you say that it changes your life completely. it seems as if a switch was thrown when told of the cancer, meaning nothing is ever the same in your life.
