Most commonly men present with a painless subareolar mass. It is difficult to accurately predict the course of the disease for the individual woman. Research that relates gene expression profiles of the primary tumor to metastatic behavior may provide useful biomarkers that may be helpful in clinical decision making in the future.
Staging Breast Cancer Although breast cancers appear to begin in the ductal or lobular epithelium there is a wide variation in their growth and development. PNX means that the lymph nodes cant be assessed for example if they were previously removed. There may be exceptions but for the most part these tumors grow first within the duct system.
