Male breast cancer (MBC) may occur more frequently in men with some of the following characteristics: never married, Jewish ancestry, previous benign breast disease, gynecomastia (breast enlargement in males), history of testicular or liver pathology, positive family history of breast cancer, or prior chest wall irradiation. As with women, aging is one of the largest risk factors behind male breast cancer.
