BACKGROUND: Male breast cancer (MBC) is rare and often treated using evidence from female breast cancer (BC) trials due to limited male participation. Previous estimates lacked global coverage and completeness. We aimed to quantify the global MBC burden from 1990 to 2021 and evaluate its current status and trends. METHODS: Based on the global burden of disease (GBD) database, we gathered and analyzed data on the incidence, death, and disability-adjusted life years (DALYs) of MBC while utilizing age-standardized rates (ASRs) as indicators for these measurements. Our study calculated the estimated annual percentage change (EAPC), aiming at measuring the average change in ASRs. Additionally, we evaluated the attributable risk factors (RFs) and trends of MBC across different regions and age groups worldwide. RESULTS: In 2021, the global MBC age-standardized incidence rates (ASIR), age-standardized death rates (ASDR), and age-standardized DALY rates (ASDALY) per 100,000 persons were 0.941 (95% UI, 0.605-1.155), 0.335 (95% UI, 0.232-0.409), and 9.157 (95% UI, 6.116-11.423), respectively. In comparison to 1990, these rates have increased by 2.212 (95% UI, 2.047-2.378), 0.664 (95% UI, 0.562-0.767), and 0.853 (95% UI, 0.750-0.956) respectively. In Uganda 2021, the ASIR and ASDR of MBC were the highest at 4.541 (95% UI, 3.028-6.808) and 3.510 (95% UI, 2.301-5.195) per 100,000 persons, respectively. Moreover, the burden of MBC exhibited an increase with age. Globally, dietary risk was t...
