Excerpt
Modern understanding of breast cancer as a disease has undisputedly left the “Halstedian” worldview and has entered the molecular age. Formerly, breast cancer heterogeneity was defined simply by measurable differences such as nodal involvement or tumor size and subsequently by steroid hormone receptor positivity. Yet, the groundbreaking discoveries of Perou et al. [
1] have taught us that there are distinct molecular subtypes of breast cancer that even carry clinical relevance with regard to patient outcome [
2]. The fact that these subtypes and their clinical impact on breast cancer outcome can be consistently identified across data sets strongly suggests that they are indeed indicative of distinct intrinsic biological properties and behavior [
3]. …
