Objective：To study the  clinical features and treatment of male breast cancer.
Methods：The clinical data of 14 cases of male breast cancer admitted in our hospital during past 14 years were analyzed retrospectively.
Results：Of the 14 patients, 7.1 percent （1/14）  was medullary carcinoma, the other 92.9% （13/14） were invasive ductal carcinoma. The tumor diameter was 1.5-5.2 cm.  Three patients underwent radical mastectomy and axillary lymphadenectomy, 10 patients had modified radical resection, and one patient had simple mastectomy. The lymph node metastasis rate was 71.4%. Twelve patients were followed up for 9 months to 12 years,  of them 3 cases died, 3 cases survived with tumor, 6 cases survived tumor-free, and 2 cases were lost to follow-up. The 5, 10-year survival rate was 58.3%, 16.7%, respectirely.
Conclusions：The majority of male breast cancer cases were invasive ductal carcinoma which could easily develop lymph node metastasis, and has a poor prognosis and low survival rate.
