Abstract

Objective: to analyze the relationship between mammographic screening and detection of breast cancer in Brazilian women aged 40 to 69, between 2009 and 2012. Method: observational, descriptive study, carried out with data collected in 2014 in the database of the Informatics Department of the Unified Health System and of the Brazilian Institute of Geography and Statistics.

Results: the incidence rates of malignant neoplastic lesions detected by palpation and imaging increased in the years 2009 and 2011, but there was a decrease in detection by palpation in 2011 and 2012. Conclusion: the proportion of women who underwent mammography increased by age group investigated, but the values are still below the recommended.
