Two recent papers have contributed to the establishment of a more precise molecular classification of breast tumors. Breast cancer is a heterogeneous disease that comes in several clinical and histological forms. Its clinical progression is difficult to predict using the current prognostic factors and its treatment is therefore not as effective as it should be. Mortality due to breast cancer is decreasing in most western countries because of mass screening frequent use of post-operative chemotherapy and or hormone therapy and the recent introduction of new drugs. However novel drugs and therapeutic strategies could be more successful if we understood breast cancer heterogeneity better. Two recent papers in Genome Biology from the laboratories of Carlos Caldas 1 and Eric Miska 2 use molecular methods to classify breast cancers more precisely. Breast cancer heterogeneity Because breast cancer heterogeneity arises from many different factors several directions of research must be pursued simultaneously if we are to understand and cope with the different forms of breast cancer. These are to determine the cell of origin to determine the molecular alteration s to
