I had partial removed in May 1988 never took medication. Than in May 2006 they found another lump on my thyroid went in to remove the rest of the gland and discovered the other half was growing back. Doc said meds suppress gland growth and that it is one of many that grows back. Also each surgery involved taking gland out to test for cancer (found none). Fyi 50 % of autopsies show non cancerous lumps on thyroid glands of all ages. Can you say pharma scam🤪
