Global and regional burden trends in breast cancer from 1992 to 2021
In 2021, the global estimated number of deaths from breast cancer was 660.93 thousand (95% UI 609.17 to 707.18, Table 1). Table 1 presents global and regional breast cancer mortality data for 2021, including all-age rates, age-standardized rates (ASRs), and net drifts from 1992 to 2021. Figure 1 and Supplementary Figure S1 illustrate mortality rates (both all-age and ASRs) in 2021 across countries, as well as their net drifts over 30 years. In 2021, the global all-age mortality rates per 100,000 were 16.81, with an ASR of 14.55. From 1992 to 2021, mortality has declined slightly {net drift = -0.38%, [95% confidence interval (CI): -0.41 to -0.34] (Table 1).
