Hi im 51 and i could have started screening at 47, so fir i have declined, this is just my personal choice. We have no known breast cancer in my family and only 1 known other case of cancer. I don't smoke and only took the pill for a year as a teenager. I too eould have untrasound if offered, but even that is not perfect especially for the breast tissue of older women. I may change my view in later years though
