Can men get breast cancer too? The answer is yes. The incidence of breast cancer in men is low, accounting for about 1% of all breast cancer patients. Male breast cancer can occur at any age, with a median age of onset of 65-67 years, about 10 years later than female breast cancer. The specific factors that contribute to the development of male breast cancer are not known, but the following may increase the risk of breast cancer in men: abnormal sex hormone levels, history of male breast disease, history of chest wall radiation therapy, family history of breast disease, history of liver disease (e.g., cirrhosis), and long-term estrogen use for prostate enlargement. The most common clinical manifestation of male breast cancer is a painless lump, similar to female breast cancer, which is usually ill-defined and hard in texture. Other clinical signs include bloody nipple overflow, nipple retraction, nipple or local skin ulceration, fixation of the lump to the skin or pectoral muscle and enlarged axillary lymph nodes. Male breast cancer should be differentiated from gynecomastia, breast abscess and metastatic breast cancer (primary tumors from other sites metastasized to the breast).
