I was diagnosed with papillary thryoid cancer 2 years ago and had my entire thyroid removed. After the surgery I wasn't losing any weight or gaining, while eating a healthy diet, so I began an exercise program 3 days a week with a personal trainer. That was over a year ago. I haven't lost an ounce. I am healthier and I've lost almost 3 dress sizes, but no weight. I know I've gained some muscle; however, will I ever lose the pounds?
