Objective: Quantifying the findings of injuries BIRADS 1 to 5 in screening mammograms in Goiás from 2010 to 2013. Methodology: Analytical ecological study of time trends of design, which evaluated the findings of BIRADS 1-5 in mammography screening between 2010 and 2013. The data source used was the Information System of Breast Cancer. The quantified variables relate to the character of BIRADS classifications of the general population. The selected groups were aged between 0 and 100 years of age. Data were analyzed by central tendency and relative frequency. Results: In the years 2010-2013, from a total of 205,131 mammograms, 199,728 were performed for breast cancer screening, being the highest number of cases (22%) aged 45 to 49 years, followed by 20% in the age group 40 to 44 years. Among the mammograms performed by screening, the majority (51.3%) was found BIRADS1 category, and minority (0.17%) was found BIRADS5. The BIRADS 1 findings were led by the ages of 45 to 49 years (24.3%), while among BIRADS5 results, the highest number of cases was found between 50 and 54 years (19.1%),. Among which 7.5% had high risk for breast cancer and 8.8% had never been examined and did not have previous mammograms, followed by the age group of women over 70 years (15.9%). Conclusion: This study allowed us to detect a predominance in classifications BIRADS 5 in women between 50 and 54, which is considered an age of risk for breast cancer. In addition to realizing a significant number of women did not undergo prior tests for detection early disease. This underscores the importance of breast cancer screening not only by radiology, but also by clinical examination, to reduce morbidity and mortality from breast cancer through early diagnosis. Key word: breast cancer.
