An update on breast cancer prevention.

BACKGROUND

Breast cancer is a significant cause of morbidity and mortality in Australia with one in seven women diagnosed in their lifetime, and one in 53 dying by age 85 years. Breast cancer screening is a vital tool in early detection but does not prevent cancer.

OBJECTIVE

This article provides general practitioners (GPs) with evidence-based strategies for breast cancer prevention. It outlines breast cancer risk factors, personalised risk assessment tools, and the role of lifestyle modification, risk-reducing medication and risk-reducing surgery. Resources are included to assist GPs to educate, empower and support women to access prevention information.

DISCUSSION: Population-level prevention targets modifiable risk factors, including obesity, alcohol use and physical inactivity. However, individual risk varies widely due to genetic and non-genetic factors, requiring a personalised approach. GPs play a key role in helping women understand their risk and make informed decisions about prevention options, aligned with their values.
