Bold claim: global breast cancer cases could surpass 3.5 million annually by 2050, up from about 2.3 million in 2023. And the death toll may rise by roughly 44%, from 764,000 to around 1.4 million in the same period.
A team led by Kayleigh Bhangdia of the University of Washington in Seattle analyzed global data and highlighted a stark reality: the burden is not shared evenly. While high-income countries often benefit from screening, timely diagnosis, and comprehensive treatment, the surge in breast cancer is shifting toward low- and lower-middle-income countries. There, people frequently face later-stage disease, limited access to quality care, and higher mortality, risking to derail progress in women’s health.
Despite representing only about 27% of new cases worldwide, women in low- and lower-middle-income countries bear more than 45% of breast cancer-related ill health and early death. This disparity is driven by shortages of radiotherapy equipment, chemotherapy drugs, and the high cost of care, according to the researchers.
The study drew on population-based cancer registries, registration systems, and interviews with family members or caregivers of women who died from breast cancer. It provides updated global, regional, and national analyses of the breast cancer burden and risk factors from 1990 to 2023, with projections through 2050 across 204 countries and territories.
Global breast cancer indicators (examples)
- 1990: 924 thousand cases, 363 thousand deaths; ASIR 42.4 per 100,000, ASMR 17 per 100,000
- 2023: 2,300 thousand cases, 764 thousand deaths; ASIR 49.3 per 100,000, ASMR 16.1 per 100,000
- 2050: 3,560 thousand cases, 1,370 thousand deaths; ASIR 49.1 per 100,000, ASMR 16.7 per 100,000
The study identifies six modifiable risk factors responsible for more than a quarter of the global burden: nearly 11% of cases link to high red meat consumption, 8% to tobacco use, 6% to high blood sugar, 4% to a high body mass index, and 2% each to alcohol use and physical inactivity.
The authors call for a coordinated global response: stronger prevention policies, increased investment in cancer care infrastructure in resource-poor settings, and universal health coverage that includes essential breast cancer services.
Co-author Dr. Olayinka Ilesanmi of the Africa Centres for Disease Control and Prevention notes that low- and middle-income countries face the toughest odds as they experience lifestyle and demographic shifts while health systems remain under-resourced. Shortages of radiotherapy machines, chemotherapy drugs, pathology labs, and costly standard treatments hamper outcomes, even as survival improves in some high-income countries due to better screening and treatment access.

The key takeaway remains clear: without accelerating prevention, financing, and access to care, the global breast cancer burden is poised to climb, with the most significant impact falling on lower-resource regions. Would you support stronger international funding for cancer care infrastructure, even if it means reallocating resources from other health priorities? Share your thoughts in the comments.
