Besides revealing masses that may be tumors, digital mammography – a technique in which low-dose X-ray images are captured and enhanced using computer technology – can reveal buildup of calcium in the arteries in the breast. About 13% of women are estimated to have this buildup, called breast arterial calcification, or BAC, including about 10% of women in their 40s and around half of women in their 80s.
Early studies so far have found BAC's presence appears to signal an elevated risk for heart attack, stroke and other cardiovascular consequences. Research has begun to reveal a link between calcium buildup in the breast and coronary artery calcification, an established measure that helps predict cardiovascular disease risk.
