Male and female disparities in breast cancer epidemiology: A comparative cross-sectional analysis of a Brazilian cohort (2017-2021).

Male breast cancer (MBC) is a rare condition, accounting for approximately 1 % of all breast cancer cases. Nevertheless, the paucity of MBC-specific research has impeded a thorough understanding of MBC. In this study, we aimed to delineate the epidemiological implications of MBC in Brazil and benchmarked it against female breast cancer (FBC).
