Enhancing the Public Health Benefits of Mammography Screening by Informing Women of Both Breast Cancer and Breast Arterial Calcification Results: A Randomized Trial to Promote Cardiovascular Health

The purpose of this research study was to determine the potential benefits of adding information on patients' breast arterial calcification (BAC) results to the standard results letter women receive after mammography. In addition to looking for potential breast cancer, research shows that mammograms can also detect the presence of calcifications within the breast arteries. Those calcifications can be associated with coronary artery disease. Women are not currently routinely told whether or not they have BAC; that is, it's not part of standard national practice to communicate that information to patients. However, previous research has suggested that patients would like to be informed about the BAC status more often. In this study, the team had two goals. First, the team wanted to measure the rates of BAC in a large, representative sample of 5492 women.

Second, the study team wanted to understand the effects of providing women with the BAC results as part of the standard post-mammography letter. Specifically, the study team wants to see how sharing BAC information might affect women's healthcare choices and lifestyle. The research includes 527 randomized women in this second part of the study, which is the first in the literature to explore women's reactions to the BAC results. If research shows that women find the information useful, BAC information may be given to women regularly in the future.
