WOW, that is me EXACTLY! Ten years ago with my first b/c (DCIS), I did lumpectomy, rads and then tamoxifen for 5 years. RIGHT AFTER I finished my 35x of rads, I was diagnosed w/Hashimoto's hypothyroidism. So then they had to take half my thyroid & parathyroids out. Then last week my doc noticed my shakiness & blood results and she thinks I'm now Hyperthyroid. Jeeze. Too much or too little--that is my life!
But I've wondered for a long time whether my radiation had anything to do w/my hypothyroidism..."they" say it's "highly targeted", but I really wonder how many of us have had the same thing happen?
