BREAST-DENSITY CHANGES LINKED TO CANCER RISK
Many middle-aged and older women get mammograms every one to two years to screen for breast cancer. When specialists read these mammograms, they assess breast density along with signs of cancer, comparing a woman’s previous mammograms to her most recent one to look for worrisome changes. But some changes are difficult to detect by eye. A study by researchers indicates that previous mammograms hold underutilized data that could help identify women at high risk of breast cancer.
