Objectives: To quantify the aspiration punction findings used in the diagnosis of malignant breast lesions in Brazil since 2010 to 2015. Methodology: Analytical ecological study with temporal bias of outline that assessed the findings of breast aspiration biopsies over the last six years. The data sources used were SISMAMA (Breast Cancer Information System). The quantified variables refer to the character of injuries and age of the overall population. The selected groups were aged between 0 and 100 years of age. Data were analyzed by central tendency and relative frequency. Results: The findings have been analyzed referring to benign processes, suspicious for malignancy, indeterminate malignancy and positive for malignancy. In individuals aged less than 10 years, 90% of the findings were benign (95% CI: 76.9% – 96%). Regarding to the malignant findings, the age range between 45 and 55 years corresponded to the most of the findings equivalent to 27.55% (95% CI: 26% – 29%). About the compatible indeterminate malignancy findings, the most correspondence was in the same age group accounting for 31.6% (95% CI: 28.5% – 34.9%). Conclusion: The study has served to enhance the health system needs for the services of high complexity due to the prevalence of types of breast cancer who require aggressive treatment and that are more prevalent, especially in the corresponding age group 45-55 years.
