Women are more confused than ever about mammograms and breast health.

Conflicting information has left some real questions regarding when to test, how often to test and the risk of testing and biopsy.

Health professionals are worried that the misinformation will discourage women from getting screened and leave them unnecessarily concerned over potential risks.

Screening guidelines have been controversial for decades, but the issue exploded nearly two years ago when the U.S. Preventive Services Task Force recommended against routinely providing the screening for women in their 40s. The task force said the decision should be based on individual considerations and said overscreening caused stress, unnecessary testing and other negatives outcomes.
