Having ADH increases the risk of breast cancer.,NCI: A benign (not cancer) condition in which there are more cells than normal in the breast lobules and the cells look abnormal under a microscope. Having atypical lobular hyperplasia increases the risk of breast cancer.,NCI: A neoplastic process that arises from the terminal ductal lobular unit of the breast parenchyma. It is usually solitary and confined to a single lobular unit. It is characterized by the presence of a monomorphic epithelial proliferation in a cribriform, micropapillary, or solid growth pattern. Focal architectural features of low grade ductal carcinoma in situ are present. There is an increased risk for development of invasive breast carcinoma.
