The diagnosis and management of pre-invasive breast disease: Ductal carcinoma in situ(DCIS) and atypical ductal hyperplasia (ADH) – current definitions and classification (2003)

Pinder, Sarah E, Ellis, Ian O

Abstract Intraductal epithelial proliferations of the breast are at present classified into three groups; distinction is made histologically and clinically between usual epithelial hyperplasia and...
