I don't know you but I read your blog. Glad to hear the good news about your greatly rdueced chances for breast cancer, thank goodness! I want to reiterate what your doctor said about the radiation exposure. Thyroid cancer is on the rise in women in the US. Over a lifetime radiation can build up. I'd also suggest fewer dental x-rays since it's a correlating factor. Find a dentist who will respect your wishes. That lead apron dentists use doesn't usually cover the thyroid. May your life be VERY long and happy!
