Dense Breast Notification and Supplemental Screening: A Survey of Current Strategies and Sentiments

Dense breast parenchyma obscures breast lesions and has been shown to be an independent risk factor for development of breast cancer. An ever-increasing number of states have approved laws requiring patient notification of dense breast tissue. Reviews of supplemental screening imaging modalities are available, but there is no consensus and little discussion regarding what radiologists are specifically doing to manage patients with dense breasts. Our goal was to survey breast imagers facing these issues in an effort to simplify dense breast management. A survey was administered via email to the Society of Breast Imaging member directory, designed to collect information regarding current practices in dense breast notification and supplemental screening. There were 223 surveys completed to entirety, including 38% from respondents in states without mandatory breast density reporting laws and 62% from states with reporting laws. A majority of respondents from both groups, 60% and 51% in those without and with laws, respectively, felt they lacked adequate resources to offer or sustain supplemental screening. In those offering supplemental imaging, the modalities offered varied widely as did the manner of offering a supplemental exam. Levels of satisfaction, concerns, and standard practices of respondents were also queried. Strategizing optimal imaging approaches and algorithms to handle dense breast management issues is important to maintain efficiency in breast imaging departments. Sharing current ideas and practices may facilitate a smoother workflow in mandatory dense breast reporting and supplemental imaging, allowing breast imagers to correct or prevent systems-based flaws.
