Figure 5From: Hormones, receptors, and growth in hyperplastic enlarged lobular units: early potential precursors of breast cancerStages of breast cancer evolution. This figure shows representative photomicrographs of important artificially defined stages of the Wellings–Jensen model of 'ductal' breast cancer evolution, including normal TDLUs, HELUs, ADH, DCIS, and IBC. ADH, atypical ductal hyperplasia; DCIS, ductal carcinoma in situ; HELU, hyperplastic enlarged lobular unit; IBC, invasive breast cancer; TDLU, terminal duct lobular unit.Back to article page
