Abstract

Male breast carcinoma is a rare diagnosis and represents 1% of all breast cancer diagnosed each year. Although rare, male breast carcinoma incidences appear to be increasing over time. In contrast, prostate cancer is the second most common cancer in men worldwide. In this article, we present a patient diagnosed synchronously with metastatic male breast cancer and prostate cancer. By presenting this patient with a synchronous diagnosis with metastatic male breast cancer and prostate cancer, we speculate on possible cancer etiologies and risk factors.
