New Advances in Breast Density Reporting and What It Means for Patients and GPs

In this episode of This Could Save Your Life podcast, Dr Catherine Bourke is joined by Dr Tessa McLean for an in-depth discussion on the clinical relevance of breast density and its reporting in breast cancer screening. Focusing on the recent rollout of breast density reporting through BreastScreen programs across several Australian states, and what this means for patients and general practitioners.

They talked about the clinical relevance of breast density for both cancer risk and the diagnostic performance of mammography. The masking effect of dense breast tissue can lower mammography sensitivity, making early cancer detection more challenging.

They explored how GPs can support patients who receive a dense breast notification, recommending the use of validated breast cancer risk assessment tools like iPrevent for individualised risk evaluation. While breast density is one factor, several points were raised about the importance of considering other risk factors including family history, genetic susceptibility, and lifestyle.

Recommendations were provided for follow-up: women should consult their GP for assessment and discussion of additional screening if needed, guided by new Department of Health resources.

Concluding with strategies for risk reduction, including exercise, maintaining a healthy weight, reducing alcohol intake, not smoking, and breastfeeding where possible.
