ALH = atypical lobular hyperplasia; DIALH = ductal involvement by cells of atypical lobular hyperplasia; LCIS = lobular carcinoma in situ; LCIS pleo = LCIS pleomorphic; CCC = columnar cell change; CCH = columnar cell hyperplasia; CCC with atypia = columnar cell change with atypia; CCH with atypia = columnar cell hyperplasia with atypia; n = number of cases. χ2 test for trend: p = 0.03.
