Centro Universitário UNIRGTo analyze the prevalence of the main indications for diagnostic mammography, its importance and its most common radiological findings. A cross – sectional study based on data collected from the Breast Cancer Information System (SISMAMA) based on data from mammograms performed in Tocantins from January 2010 to December 2013. During the analyzed period, 50,654 mammograms were performed in women in the state of Tocantins. The prevalence was between 40-49 years (41.28%). Screening mammograms averaged 97%, and diagnostic mammograms accounted for 3% (n = 1,531). The main indication for diagnostic mammography was the presence of some findings in the clinical examination of the breasts, corresponding to 74.4% of the cases, followed by radiological control of the BIRADS 3 lesion, with 17.9%. Mammography for evaluation of the neoadjuvant chemotherapy response accounted for 6%, and for follow-up of the cancerous lesion, 1.7%. No radiological findings were found in 63.22% of diagnostic mammograms. The results with BI-RADS 1 prevailed, with 35.20% (n = 539) and BI-RADS 5 and 6 counted, added, 2.4%. Microcalcifications in the right breast were found in 4.6% of diagnostic mammograms and 4.44% in the left breast. The left breast nodules were superior to those found in the right breast (13% versus 10.9%). The clinical examination of the breasts is extremely important, since they represented the main indication for diagnostic mammography (74.4%), while mammograms for the follow-up of malignant lesions corresponded to a smaller percentage (1.7% ). Due to the severity of breast cancer, diagnostic mammography becomes fundamental as a method of detection and intervention in the disease. Among its radiological findings, the BI-RADS 1 lesion had a higher prevalence (35.2%), the microcalcifications were more common in the right breast and the nodules in the left breast.Breast neoplasm, Diagnostic Mammography, Microcalcifications
