Table 3 Clinical and histological data relating to the benign (Ben.) and malignant (Mal.) breast tissues. Data includes patient menopausal status and histological type, and tumour size, T, N, M, UICC stage, grade, ER, PR and HER2/neu status and intrinsic subtype of malignant tissues where available

From: Evaluation and validation of candidate endogenous control genes for real-time quantitative PCR studies of breast cancer
