Most breast cancers in men are ductal carcinomas. Ductal means the cancer started in the milk pipes of the breast, called ducts. These cancers are usually invasive because they start inside the duct and then break through the wall of the duct, growing into the normal surrounding breast tissue.
Analysis of relative survival according to the treatment showed that survival was longer for patients treated with surgery + radiotherapy + hormone therapy: 89% at 5 years. Scarff, Bloom and Richardson grade was independent prognostic factor of survival. Male breast cancer is a rare disease with a poor prognosis, and diagnosis is often made at an advanced stage.
