Cancer group's mammogram advice: Start later and get fewer

The American Cancer Society now says women should start mammograms later in life and get fewer of them, a stance that puts the trusted group closer to an influential government task force's advice. In new guidelines out Tuesday, the cancer society recommends that most women should begin annual screening for breast cancer at age 45 instead of 40, and switch to every other year at 55. The task force advises screening every other year starting at age 50. It's not a one-size-fits-all recommendation; both groups say women's preferences for when to be scanned should be considered.
