Australian General Practitioners' Current Knowledge, Understanding, and Feelings Regarding Breast Density Information and Notification: A Cross-Sectional Study

Background: There is a lack of evidence around Australian general practitioners' (GPs) views of issues surrounding breast density. The current study aimed to quantitatively assess GPs' current knowledge, understanding, and feelings around breast density information and notification. Methods: This study involved a cross-sectional survey using an online platform to collect quantitative data from Australian GPs. Survey data were analysed with descriptive statistics. Results: A total 60 responses from GPs were analysed. Most (n = 58; 97%) had heard or read about breast density and nearly 90% (n = 52; 87%) have had discussions about breast density with patients. Three-quarters (n = 45; 75%) were supportive of making breast density notification mandatory for patients with dense tissue and a similar proportion (n = 45/58; 78%) felt they need or want more education on breast density. Conclusions: There is strong support for notifying patients of breast density, and interest in further education and training among the surveyed GPs. As GPs play a central role in cancer prevention and control, their involvement in discussions related to breast density notification, evaluation and appraisal of evidence, development of communication strategies, and participation in ongoing research on the topic will be indispensable.
