Breast Density and BMI Both Play a Role in Breast Cancer Risk
Laws in many states require notifying women if they have dense breasts, a risk factor for breast cancer. But density shouldn’t be the only factor in determining whether supplemental screening is warranted, reported researchers in a large new study led by UC San Francisco and UC Davis.
Body mass index (BMI) should also be considered, the researchers say. Their study analyzed more than 2.6 million breast density measurements at 140 radiology facilities around the country.
