Breast cancer is the most common cancer in women worldwide, but survival rates vary greatly depending on where a woman lives. A new study using global data reveals detailed pictures of breast cancer trends and disparities across countries.
According to the research, wealthy nations have more breast cancer diagnoses, while low- and middle-income countries face higher death rates due to limited access to early detection and treatment. This disparity affects even young women in poorer regions, where those under 50 are four times more likely to die from breast cancer than their counterparts in high-income countries.
The study’s findings, published in Nature Medicine, aim to inform health policies worldwide to improve breast cancer diagnosis and treatment. The research analysed global data on breast cancer cases and deaths in 2022 and projected the impact in 2050 across 185 countries.
