Male breast cancer is a rare disease in which the underlying pathogenesis seems to be associated with the presence of a hormonal imbalance resulting in a relative hyperestrogenemic state. Most male breast cancers are infiltrating ductal carcinomas and tend to present at a later stage with a longer interval between the onset of symptoms and the initiation of therapy as compared to female cases. The treatment approaches are based largely on experience from treatment of female breast cancer. T stage and nodal status, as in female breast cancer, are important predictors of outcome for male breast cancer. It remains controversial whether survival is equivalent on a stage for stage basis when compared to female breast cancer.
