Is Breast Density Influenced by Genetics?

Among the questions that Dr. Vachon and her team are exploring in the Mayo Mammography Health Study at Mayo Clinic is whether breast density is influenced by genetics.

Even though higher breast density is one of the strongest risk factors for breast cancer, there is little understanding about how breast density might influence breast cancer.

Identifying genetic variation associated with breast density could provide clues to better understand the relationship between breast density and breast cancer.

Ultimately, this mammography research might lead to better identification of people with breast cancer, to improved prevention of breast cancer and to more treatment options.
