Breast cancer is predominantly recognized as a condition affecting women, however, male breast cancer (MBC), despite its rarity, represents a significant and serious malignancy in men. Accounting for approximately 1% of all breast cancer cases, MBC is often diagnosed at a later stage compared to female breast cancer, primarily due to a lack of awareness and the absence of screening programs tailored for men. This delayed diagnosis typically results in poorer prognoses and more limited treatment options. Over the past decade, there has been a notable increase in research and awareness surrounding MBC. This surge is largely driven by the recognition of its unique epidemiological and biological characteristics, which are distinct from those of female breast cancer. However, due to its low incidence, many aspects of MBC, including its etiology, clinical presentation, and optimal treatment strategies, remain inadequately understood. This paper aims to provide a comprehensive review of MBC by examining its incidence, mortality rates, and epidemiological characteristics on a global scale. Additionally, it explores the economic burden associated with the disease, identifies key risk factors, and discusses current preventive measures. Finally, the paper will offer insights into future research directions and potential advancements in the diagnosis and treatment of MBC.
