Early detection of breast cancer by mammography is one of the care modalities for the control of breast cancer. Current transversal and descriptive study analyzes the production of mammograms within the NHS, following information by patients and tests, and investigates the registration of mammograms in Brazil between 2009 and 2014. Information was obtained from the Information System for the Control of Breast Cancer. Low covering rate occurred in northern Brazil. A higher percentage was evidenced for whitefemales with incomplete basic schooling. With regard to categories within the Breast Imaging Reporting and Data System, benign results were high among Brazilian females. More frequent behavior within a two-year period was recommended. Knowledge on socio-demographic variables in the screening of breast cancer may identify risk groups for the undertaking of such procedure.
