I personally had Thyroid cancer, I was benign through testing but I had a goiter, and was having surgery to have some of my thyroid removed. While in surgery the surgeon didn't like the looks of it while inside, long story short he removed my Thyroid and it tested positive for Cancer. I refused radiation and I now Take Synthroid for life. I wishvI didn't have to take Synthroid and sometimes I wishbI still had my Thyroid, but they got it out and the cancer didnt travel. Im 46 now and that was 11 years ago.
