I have just come back from my appointment regarding I131 treatment and the doctor surprised me by saying that he really didn;t think that it was necessary. I have had a total thyroidectomy (2 surgeries) and only 1 tumour was found. (1.8cm papillary)I am 54 years old. I was prepared to have the treatment and the doctor says that he is OK with doing it but doesn;t think that it is necessary. He said that my cancer will NOT come back. Has anyone else had to face this decision? I would love to hear your experiences.
