Breast cancer in women under 40 years: preoperative detection by mammography.

摘要: Introduction: This article assesses the diagnostic sensitivity of mammography in preoperative detection breast cancer young women. Materials and Methods: We retrospectively reviewed 1010 women with carcinoma between January 1996 September 2002. The patients were identified from pathological reports. Of these, 237 below 40 years age, accounting for 23.5% all cancers. Only 76 had mammograms performed prior to surgery. Seventy-five also ultrasonography performed. Histological types proportions each type compared those found a consecutive series 773 carcinomas above age seen during same period our hospital. patterns, as on mammograms, classified follows: fatty, scattered fibroglandular, heterogeneously dense homogeneously dense. Specific features mass, microcalcifications, architectural distortion asymmetrical density evaluated. Results: Ofthe who surgery, 81 cancers found. patients' ranged 25 years, mean 36.4 years. parenchymal patterns 6.6%, 67.1% fibroglandular 26.3%. Abnormal mammographical findings present 93.8%. most common mass 60% or without associated abnormality, 28.7%. frequent tumour (82. 7%) was invasive ductal carcinoma, which is not significantly different older (P = 0.895). Ultrasonography showed solid masses 73 negative other 2 patients. Conclusion: Mammography useful imaging technique providing diagnosis clinical suspicion malignancy. Mass microcalcifications are abnormal study.
