New Data Shines Light on Australians Living with Metastatic Breast Cancer
25 May 2026
In November 2025, the Australian Institute of Health and Welfare reported that around 20,950 Australians were living with metastatic breast cancer at the end of 2024, including approximately 20,800 women and 150 men.
The figure is more than double a previous estimate released in 2020, highlighting the need for better data to understand the true number of people living with advanced breast cancer and to improve planning for healthcare services and support.
The national estimate was developed using linked health data from cancer registries, hospital records, and pharmaceutical information. It is believed to be the first approach of its kind worldwide.
Breast Cancer Network Australia is now working with the Australian Cancer Data Alliance to support ongoing data collection and ensure metastatic breast cancer remains part of Australia's long-term cancer data planning.
Internationally, progress is also being made. In the United Kingdom, the government has committed to defining and counting recurrent cancers, beginning with metastatic breast cancer. In Canada, health organisations are exploring new ways to improve data collection, with plans to begin pilot programs in selected provinces.
Despite these advances, advocates say more work is needed to ensure people living with metastatic breast cancer receive appropriate care and support. They also highlight the importance of improving health equity for people in regional and remote communities, Indigenous populations, and culturally diverse groups.
BCNA says accurate and ongoing data is essential to ensure people living with metastatic breast cancer are recognised, represented, and considered in healthcare planning and policy decisions.
The organisation remains committed to working with partners in Australia and overseas to improve awareness, support, and outcomes for everyone affected by metastatic breast cancer.
