Abstract
RATIONALE AND OBJECTIVES: To determine awareness and knowledge of breast density and breast density legislation among women receiving routine mammography following passage of Massachusetts breast density legislation. MATERIALS AND METHODS: A survey assessing breast density awareness and knowledge was administered to all women receiving screening mammography over two separate 1-week periods at an academic medical center following implementation of mandatory breast density notification. Survey questions queried sociodemographic factors, breast density knowledge, legislation awareness, and medical decision-making intent. RESULTS: Of 1000 survey recipients, 338 (33.8%) returned their survey. Most women were surprised (207/338; 61.2%) to receive their breast density notification letter and unaware (302/338; 89.9%) of newly implemented breast density legislation. The majority (185/338; 54.7%) of survey respondents self-reported having dense breasts. Only 61.1% (113/185) of women with dense breasts reported that their personal breast density increased breast cancer risk, while only 60.0% (78/130) of women with non dense breasts reported that their personal breast density did not increase breast cancer risk. Significant differences between women with dense and nondense breasts were observed related to intention to follow-up with a health practitioner (118/185; 63.8% vs. 66/130; 50.8%, p = 0.03) and views on necessity of supplemental screening based on personal breast density (83/185; 45.1% vs. 20/130; 15.4%, p < 0.01). CONCLUSIONS: Despite implementation of state breast density laws since 2009, confusion and misinformation about breast density persists among women receiving mammography screening. Innovative tools that more effectively inform patients, may be required to improve communication and patient understanding about breast density and subsequent breast care management.
