American Cancer Society says women should get mammograms later

Updated guidelines recommend annual breast cancer screenings at age 45 instead of 40 and less often, switching to every other year at age 55

New mammogram advice from the American Cancer Society says most women should start annual screenings at age 45 instead of 40, a change that moves the group closer to guidelines from an influential advisory taskforce.

The cancer group also now advises switching to screening every other year at 55. The taskforce recommends starting routine screening for breast cancer at age 50, then every other year.
