In 2013 an MRI discovered that I had growths on my thyroid. Since then I have kept them checked with FNA test and blood work, blood work and FNA have always been good. I'm now 49, and not the weight I once was just a 2 years ago 5'6 (145 now 175). I would say I eat very healthy. So, my question is why is my thyroid planting crops so to speak.
