Australia has one of the highest breast cancer incidence in the world, according to a new global study, which analysed data from 185 countries.
While our mortality rates remain on the lower end of the scale, this data highlights the importance of awareness and prevention efforts in this space.
The latest study also found that breast cancer incidence rates were highest in Australia and New Zealand, however, the region is reducing breast cancer mortality by 2.1% per year — progressing toward the World Health Organisation’s Global Breast Cancer Initiative goal of a 2.5% annual reduction in mortality.
Do you know the risk factors?
Professor Nehmat Houssami, NBCF Chair in Breast Cancer Prevention at the University of Sydney, says breast cancer remains a substantial global burden, with significant disparities in outcomes.
“Countries that are less affluent and have less developed health systems […] have much worse breast cancer outcomes (higher mortality) than the more developed/affluent countries,” says Professor Houssami.
“A woman who develops breast cancer in a low-middle income country has a higher likelihood of dying from her cancer than her counterpart in a high-income country.”
Professor Houssami explains that while early detection and improved treatments contribute to declining mortality rates, there are various reasons for the breast cancer incidence rates in Australia.
These, he says, include risk factors that may not be widely understood such as alcohol consumption, low physical activity, and post-menopausal obesity.
“We need to improve support for women to reduce these potentially modifiable risk factors,” says Professor Houssami.
Early screening crucial
Professor Jason Gurney, an epidemiologist at the University of Otago, notes New Zealand’s national screening program plays a key role in early diagnosis.
“Because of factors including screening, breast cancer tends to be detected when it can be successfully treated, leading to higher survival rates,” he says.
What does this mean for PAs?
Pharmacy assistants play a crucial role in supporting breast cancer awareness within their communities.
Running awareness days, and encouraging conversations around screening, risk factors and lifestyle changes — such as reducing alcohol intake and staying active — can help women take proactive steps in managing their breast health.
