Male breast cancer represents only about 1% of all breast cancers. Of 451 patients with breast cancer, we have experienced four cases of male breast cancer. Characteristics of these male patients with breast cancer were an older age at diagnosis (mean: 68.5 years old), prolonged duration of symptom (ranged from 1 month to 6 years with a mean of 25.5 months), centrally located tumor, advanced staging and infiltrating ductal carcinoma in histologic type.
