Male breast cancer is cancer that forms in the breast tissue of men. Though breast cancer is most commonly thought of as a woman's disease, male breast cancer does occur.
Male breast cancer is most common in older men, though male breast cancer can occur at any age.
Men diagnosed with male breast cancer at an early stage have a good chance for a cure. Still, many men delay seeing their doctors if they notice unusual signs or symptoms, such as a breast lump. For this reason, many male breast cancers are diagnosed when the disease is more advanced.
