For most women, who are not at especially high risk of breast cancer, regular mammograms can start at age 50. Or, to be cautious, a woman can get one mammogram earlier (around age 40 or 45) and then if it is normal, wait until she is 50 for her next mammogram.This is the advice that the National Center for Health Research and their Cancer Prevention and Treatment Fund have been giving since 2007.. Most women who have a mother, sister, or grandmother who had breast cancer at the age of 50 or older, or who are at high risk of breast cancer because of obesity or other reasons, should have regular mammograms (every one or two years) starting at age 40.
