In November of last year I went through an unsuccessfull total thyroidectomy,The day that I was discharged from the hospital I got my results from the biopsy.It had showed that I had a very small section of micro papillary cancer...I havent had any radioactive iodine treatments and havent underwent any other testing....How do you know if the cancer is all gone? is it required to have radioactive iodine?Any information that anyone can give will be greatly appreciated!
