I had open heart surgery at the age of 9 to close 3 holes in heart. Over the years I had a lot of X-rays done, I was advised by the Heart Doctors at the age of 18 to only get X-rays if absolutely necessary. I am currently undergoing chemo therapy for breast cancer, estrogen positive ductual on the right side, with mastectomy. The Dr s want me to do radiation after chemo. I feel I have already had too much radiation over the years. Also had Papillary thyroid cancer, removed 1/2 thyroid. I did have mammery cancer in the nodule taken out, did not break barrier.
