Breast density (BD) reduces sensitivity of mammography, and is a strong risk factor for breast cancer (BC). Data about women's awareness and knowledge of BD are limited. Our aim is to examine whether the BD information disclosure and BD awareness among women without BC are related to their knowledge about BC risk factors. We examined self-reported BC risk perception and its association to BD awareness and level of health literacy. A cross-sectional, single site study included 263 Croatian women without BC who had mammographic examination. Data were collected by interviews using questionnaires and a validated survey. Of the total, 77.1% had never heard of BD, and 22.9% were aware of their BD. Most participants who knew their BD (88.2%, < 0.001) had higher levels of education. Majority of subjects (66.8%) had non-dense breasts and 33.2% had dense breasts. Subjects aware of their BD knew that post-menopausal hormone replacement therapy ( = 0.04) and higher BD ( = 0.03) are BC risk factors. They could more easily access information about health promotion ( = 0.03). High-BD informed women assessed their lifetime BC risk as significantly higher than all others ( = 0.03). Comprehension of BD awareness and knowledge is crucial for reinforcement of educational strategies and development of amendatory BC screening decisions.
乳腺密度（BD）会降低乳房X线摄影的敏感性，并且是乳腺癌（BC）的一个重要风险因素。关于女性对BD的认识和了解的数据有限。我们的目的是研究无BC的女性中BD信息披露和BD知晓情况是否与她们对BC风险因素的了解有关。我们研究了自我报告的BC风险认知及其与BD知晓情况和健康素养水平的关联。一项横断面单中心研究纳入了263名接受乳房X线检查的无BC的克罗地亚女性。通过问卷调查和一项经过验证的调查进行访谈收集数据。总体中，77.1%的人从未听说过BD，22.9%的人知晓自己的BD。大多数知晓自己BD的参与者（88.2%，<0.001）受教育程度较高。大多数受试者（66.8%）乳房密度不高，33.2%的人乳房密度高。知晓自己BD的受试者知道绝经后激素替代疗法（=0.04）和较高的BD（=0.03）是BC的风险因素。她们能更轻松地获取有关健康促进的信息（=0.03）。被告知BD高的女性认为她们一生中患BC的风险明显高于所有其他人（=0.03）。理解BD知晓情况和知识对于加强教育策略以及制定修正的BC筛查决策至关重要。
