Two hundred cases of @entity0 were studied, with particular attention to adjacent non-malignant modifications considered by some authors as preneoplastic changes. @entity75 were recognized in 82% of cases. @entity1373 was present in 51.5% of cases and was more often ductal (83/200) than lobular (40/200). Microscopic cysts were noted in 72% of cases. Calcifications, easily identified by mammography were present in 20% of cases and were associated with @entity1373 in 4/5 of cases. The mean of @entity1 was 58 years. For comparative studies of histologic lesions the following age categories were evaluated: category I less than 50 years (57 @entity1 ), category II greater than or equal to 50 years (143 @entity1 ). @entity1137 , @entity3923 , and, to a lesser degree, sclerosing @entity3923 and @entity45 were more frequently associated with @entity0 in @entity1 younger than 50. Fibro- @entity3202 or lipomatous changes were more often found in the older group of @entity1 , as expected. @entity1463 @entity3923 was significantly more frequent in breasts with multifocal infiltrating @entity189 . Such changes must be considered as risk factors by pathologists when present in mammary specimens without @entity75 , and careful study should be undertaken to locate a possible in situ microscopic @entity189 . No differences appeared in lesions associated with @entity0 in @entity1 with or without a familial history of @entity0 .
