Bottom line:
IMO, don't let the medical shysters railroad you into Radiation Iodine to needlessly kill your thyroid, or radiation, needless surgery, needless biopsies under threat of a minuscule cancer risk.
BTW) Iodine is required for the entire body, not just for the thyroid. Sorry to say, but "they" don't want us taking Iodine because it is bad for business profits.
