Objectives: To quantify the histologic features of biopsy findings of malignant breast lesions in Brazil since 2010 to 2015. Methodology: Analytical ecological study with temporal bias of outline that evaluated the histopathologic findings of breast biopsies over the last six years. The data sources used were SISMAMA (Breast Cancer Information System). The quantified variables refer to the character of lesions and age of the overall population. The selected groups were aged between 0 and 100 years of age. The data were analyzed by central tendency and relative frequency. Results: findings have been analyzed referring to intraductal carcinoma in situ, lobular in situ, Paget’s disease, infiltrative ductal, invasive lobular, tubular, mucinous and medullary. In children’s age (under 14 years), there was a higher quantification of cases of ductal carcinoma Infiltrating corresponding to 52.3% of total cases for this age group. This histopathological finding was also predominant in all cases (56%). The largest number of diagnoses were made in women between 50 and 59 years of age (27%), followed by the age group of women over 70 years (17%). Conclusion: This study allowed us to detect a greater predominance of infiltrating ductal carcinoma, an invasive form of breast cancer, which reaffirms the need for specific programs for a greater reduction in mortality rates reported by breast cancer through early diagnosis.
