By: Kathy Hubbard. The U.S. Preventive Services Task Force has changed their recommendations about when a woman should start having mammograms. They now say that all women should get screened every other year starting at age 40 and continue until they’re 75.

The American Cancer Society’s website, however, still says that women could choose to have mammograms between the ages of 40 and 44 but should have them every year from ages 45 to 54. Then, at age 55 they could switch to mammograms every two years if they preferred and continue as long as they’re in good health.
