The Global Burden of Disease (GBD) Study 2023 highlights a significant rise in breast cancer incidence and mortality from 1990 to 2023, driven by population aging. Despite medical advances, it remains the leading cause of female cancer deaths globally. Variations across different Socio-demographic Index (SDI) regions reveal profound inequalities in healthcare access and clinical outcomes worldwide.

1. Epidemiological analysis from 1990 to 2023

Over the past thirty years, age-standardized breast cancer incidence has shown diverging trends. In high-SDI regions, mortality has declined due to early screening and advanced multimodal therapies. Conversely, low-SDI regions face a rapidly increasing burden linked to lifestyle changes and late-stage diagnosis, pointing to a critical shortage of healthcare infrastructure and public health awareness.

2. Forecasting the breast cancer burden to 2050

Projections indicate that the breast cancer burden will escalate further by 2050, particularly in developing nations. The rising number of new cases necessitates urgent intervention strategies from international health authorities. These forecasts provide a vital framework for resource allocation, underscoring the need for prioritized early-detection programs and enhanced global palliative care systems.

3. Implications for public health policy

The findings underscore the need for socio-economically tailored breast cancer control strategies. In resource-limited settings, establishing low-cost screening models and improving access to essential medicines are paramount. Controlling modifiable risk factors and strengthening early treatment capacities will be essential to reducing future mortality and narrowing the global gap in oncology care.
