ALH = atypical lobular hyperplasia; DIALH = ductal involvement by cells of atypical lobular hyperplasia; LCIS = lobular carcinoma in situ; LCIS pleo = pleomorphic LCIS; IIL = indeterminate in situ lesions. There was no difference in mean age among patients with different lesions (p = 0.425); n = number of cases; SD = standard deviation.
