The purpose of this quantitative and retrospective study was to analyze the prevalence of mammary alterations from 1304 women in the city of Francisco Beltrão- Paraná (PR), Brazil, registered in theSISMAMA system, froma Regional Health Center in Paraná State. Between 2009 and 2012, data was collected in May and June 2013 and statistically analyzed. The results showed that 694 (53.2%)of women were under 49 years old, 1126 (86.3%) had no increased risk for developing breast cancer, and 1205 (92.5%) underwentmammography screening. Color and tracking information were omitted in most entries. The BI-RADS (r) category 0 (inconclusive result) was the most prominent.Categories with higher chances of malignancy (BI-RADS (r) 4 and 5) prevailed in the left breast in women older than 50. Diagnosis of radial sclerosing lesions associated with infiltrating ductal carcinoma was predominant in 53.0% (n = 9) of the histopathological exams. We conclude that these findings are partially supported by the literature.
