US women to be told about breast density under new mammogram rules

FDA to require information about density of breast tissue - which can make cancer harder to spot - to be given to patients

All US women getting mammograms will soon receive information about their breast density observed during the test, which can sometimes make cancer harder to spot.

The new requirements, finalized on Thursday by the Food and Drug Administration, are aimed at standardizing the information given to millions of women following regular scans to detect breast cancer.
