I have diagnosed multinodular goiter since 2004. I have 3 times fine needle biopsy, nothing was wrong, just oversize of thyroid with nodules, never was on medication since my family doctor said my hormone level was OK, I will go 4th time biopsy this week due to size of one nodule at left lobe increased, can anyone share their experience with me on that? What is the chance of having cancer on this particular situation? I never was on diet because of my thyroid problem, any advise on diet to help me on shrinking nodule and thyroid size? Last question is trustable expert on thyroid? Name address, I would like to be ready for oncoming hormonal changes lie menapause, middle age crisis. etc. and want to take advice from good doctor. Thank You.
