BACKGROUND: The association between method of detection and @entity0 histopathology has not been assessed adequately in a population-based setting. METHODS: Among @entity1 who were included in a population-based, case-control study of @entity0 , @entity1 who were newly diagnosed with invasive @entity0 were identified from Wisconsin's statewide @entity5 registry. Only @entity1 age > or = 50 years were analyzed, because screening by mammography was not recommended before age 50 years at the time of the study. The @entity0 among these @entity1 (n = 2341 @entity5 ) included the following histopathologies: @entity1137 (n = 206 @entity5 ); @entity513 , not otherwise specified (n = 1920 @entity5 ); @entity1377 (n = 15 @entity5 ); @entity189 (n = 36 @entity5 ); mucinous @entity420 (n = 56 @entity5 ); @entity420 (n = 41 @entity5 ); invasive comedocarcinoma (n = 24 @entity5 ); @entity5223 (n = 15 @entity5 ); and mixed @entity1137 (n = 28 @entity5 ). RESULTS: Overall, @entity1 reported that 41% of @entity5 were detected by mammography, 48% of @entity5 were self detected, and 11% of @entity5 were detected by clinical breast examination (CBE). Detection by mammography was significantly more likely for @entity1 who had @entity420 (83%; P < 0.001) and invasive comedocarcinoma (67%; P = 0.23) compared with @entity1 who had @entity513 (40%). Mammography was significantly less likely to detect @entity189 (17%) than @entity513 (40%; P = 0.01). @entity1137 was the only histopathology that, compared with @entity513 , was detected significantly more often by CBE than by self detection. Mammography @entity1137 (42%) as frequently as @entity513 (40%). However, the use of postmenopausal hormones may have modified these detection patterns: Among current users, mammography discovered a greater percentage of @entity513 (51%) and fewer @entity1137 (36%) than nonusers. CONCLUSIONS: Among @entity1 age > or = 50 years, @entity0 detection by mammography, self detection, and CBE varied according to @entity5 histopathology.
