Between 1990 and 2023, China’s age-standardized mortality rate (ASMR) declined far more rapidly than in the rest of the G20 (EAPC − 1.92 vs − 0.23), whereas its ASIR rose only modestly (EAPC 0.40 vs 1.05); China’s MIR fell to the eighth lowest by 2023. Across members, SDI correlated positively with ASIR (r = 0.74) but inversely with MIR (r = − 0.84). Decomposition attributed China’s rising deaths chiefly to population aging, partly offset by declining age-specific rates. Rates in the postmenopausal age group exceeded those in the premenopausal age group in all 19 members. By 2050, China’s ASIR is projected to remain broadly stable, while absolute cases rise by approximately 131%.Conclusions: Across the G20, female breast-cancer burden is undergoing an epidemiological transition: absolute burden is rising as populations grow and age, while age-standardized mortality is declining in most members, with marked heterogeneity across the G20. The burden is shifting toward older women in the postmenopausal age group, while the mortality-to-incidence ratio remains higher in lower-SDI members. These patterns argue for G20-coordinated, equity-focused prevention and survival care.Keywords: breast cancer, global burden of disease, G20, menopausal status, sociodemographic index
