Breast cancer rates are highest in Australia and New Zealand, according to a recent study published in Nature Medicine. The research found that one in 20 women worldwide are diagnosed with breast cancer, while one in 70 die from the disease.
The mortality rate from breast cancer is falling globally, but the disparity in diagnosis rates remains significant. In Australia, one in seven women will be diagnosed with breast cancer over their lifetime, and on average, 58 people are diagnosed each day.
New Zealanders also experience a high incidence of breast cancer diagnoses, which Dr Jason Gurney, an epidemiologist at University of Otago, attributes to the country’s well-run national screening program. The study suggests that factors such as aging and risk factor profiles contribute to higher diagnosis rates in Australia and New Zealand.
However, mortality rates from breast cancer are also decreasing in these countries, with a 2.1% annual decline. This trend is part of the World Health Organization’s goal to reduce global breast cancer deaths by 2.5% annually.
While some countries, such as Malta and Denmark, are on track to meet this goal, others face significant challenges due to limited resources and healthcare systems. The study highlights the need for governments to invest in breast cancer screening and treatment services, particularly in low- and middle-income countries where access is often restricted.
Overall, the findings of this study underscore the importance of addressing breast cancer disparities and promoting equitable access to diagnosis and treatment services globally.
