Abstract
To really understand the molecular pathology of breast cancers and their initiation, it is necessary to have valid models. These models not only need to take into account the diversity of breast cancers, but also the roles of other cells, either via secreted factors and/or direct contact, found in the breast. The cell lines that are available can to a degree reflect the heterogeneity of breast cancers, but by virtue of their immortality and the methods used to achieve this, can never be truly representative of ‘real breast cancer’. The validity of breast cancer models can also be improved by consideration of 3D systems in which the other elements of the breast, in addition to the malignant epithelium, are used, notably myoepithelial cells and fibroblasts. In this way, not only can the morphological elements of breast cancer be more faithfully reduplicated, but also potentially the underlying molecular pathology. It remains true that no single model is perfect and studies using these are best done hand in hand with clinical studies.
