Simple Summary: Breast cancer is the most common cancer and the leading cause of cancer-related deaths among women globally, with over 2.26 million new cases in women in 2020. Male breast cancer, while rare (less than 1% of cases), is treated similarly to female breast cancer despite some clinical differences. Advances in treatment, such as using genomic and immunohistochemical markers, have significantly improved survival rates for women. Men with breast cancer are often older at diagnosis, and their prognosis may differ due to age and other factors. The survival analysis conducted on 2162 patients (19 males and 2143 females) suggests that male breast cancer may have a poorer prognosis compared to female breast cancer. Breast cancer is one of the most common cancers and the leading cause of cancer death in women. Less than 1% of breast cancer cases are male breast cancers. Although there has been significant progress made in the management of breast cancer, due to its rarity among men, the question of whether men and women with breast cancer have the same treatment response and survival rate still needs to be answered. The primary goal of this study is to compare survival outcomes between male and female breast cancer patients. Material and Method: This cohort study represents a retrospective and anonymized data analysis of 2162 breast cancer cases (19 males and 2143 females), registered over a period of 12 years, from 1 January 2010 to 31 December 2021, in the Clinic of Obstetrics and Gynecology, Diakoneo Diak Klinikum Schwäbisch Hall, Germany. Results: According to the Kaplan–Meier survival analysis, the estimated overall 3-year survival rate was 91.1% for women and 88.9% for men. The log-rank test of equality of survival distributions indicated a statistically significant difference in survival times between the two groups (p = 0.009). In the subsequent age-matched Kaplan–Meier analysis, the p-value was below the significance threshold (p = 0.068). Conclusions: Male breast cancer is a rare disease that may show some particularities in terms of survival compared to female breast cancer. [ABSTRACT FROM AUTHOR]
