When should you get a mammogram? Conflicting advice makes it hard to know

Deciding when to get routine mammograms is confusing due to conflicting advice from health groups, with some recommending women begin at age 40 or 45 and others at 50. The American College of Physicians recommends every-other-year mammograms for average-risk women ages 50 to 74. More than 320,000 women in the U.S. will be diagnosed with breast cancer this year.
