Dense breasts are “normal.” In fact, 40% of women over age 40 have dense breasts. But dense breast tissue can hide cancer on a mammogram and can reduce the effectiveness of mammography screening. So a “normal,” “negative,” or “benign” mammogram result does not reliably exclude cancer in women with dense breasts. This is why, sometimes, a woman with dense breasts may have cancer detected soon after a “normal,” “negative,” or “benign” mammogram. This is known as an “interval cancer.” To find cancer in a woman with dense breasts, additional screening should be considered. See flow chart: Who Needs More Screening? (or, in Europe, European Screening Decision Support Tool).Browse All Provider FAQ's
