Retrospective Analysis of 5100 Mammography Imaging in a Tertiary University Hospital

Objective: In this study, our aim is to retrospectively evaluate, in the light of literature, mammographic find­ings of 5100 patients whose mammography imaging was performed from 2010 to 2015 in the Medical Faculty, Dicle University, and Children’s and Obstetrics Hospital, Diyarbakır. Methods: We retrospectively examined 5400 mam­mograms. Since the report and age data regarding 300 cases were missing, they were excluded from the study, and hence 5100 cases were included into the study. Each patient’s age, mammography findings were evaluated. Breast imaging results were categorized according to BI­RADS (Breast imaging reporting and data system) clas­sification. Results: The mean age of 5100 patients included into the study was 51.0 years. The localization of the lesion was detected most in the upper outer quadrant in both right and left breasts (62.9% in the right breast, 58.3% in the left breast). When BIRADS 4 and 5 lesions were assessed, they all were observed to be at equal rate in both breasts, and the lesions were mainly located in the upper outer quadrant. When BIRADS scores were com­pared according to age groups, the incidence of BIRADS 4 and BIRADS 5 lesions was determined to be higher in >35 years of age than under 35 years of age, which was statistically significant (p <0.001), whereas BIRADS 3 le­sions were found more in those patients under 35 years of age. Conclusion: When mammographic imaging results of patients coming from Diyarbakir and the surrounding area were evaluated, it was determined that BIRADS 4 and 5 lesions showed increase in those cases > 35 years of age, and that they were most frequently located in the up­per outer quadrant.
