Trends in age-specific incidence, mortality, and DALYs of female breast cancer from 1990 to 2021.

Objectives: Breast cancer is a leading cause of morbidity and mortality among women worldwide. This study aims to analyze the trends in breast cancer incidence, mortality, and disability-adjusted life years (DALYs) across different age groups from 1990 to 2021, and to project the mortality rate for the next decade.

Methods: Global breast cancer data were analyzed, focusing on three distinct age groups: 15-49 years, 50-69 years, and 70+ years.
