- Breast cancer incidence in China increased by over 360% from 1990 to 2021, with age-standardized incidence rising from 9.42 to 23.65 per 100,000, significantly higher than the G20 average.
- China's age-standardized mortality rate increased slightly from 4.71 to 5.04 per 100,000 during the same period, while the G20 countries saw a decrease from 9.57 to 8.14 per 100,000.
- The most pronounced increases in incidence were observed among men aged 15-49 years old in China, and the mortality-to-incidence ratio declined in both China and G20 countries, especially in females aged 15-69.
- Projections suggest continued growth in incidence in China, particularly among those aged 50-69, while mortality is expected to stabilize or decline by 2040.
- The study highlights the urgent need for enhanced prevention, targeted screening (especially for women 50-69), and international collaboration to mitigate the disease burden.
