Ações de detecção precoce do câncer de mama no Brasil: análise dos dados do sistema de informação do controle do câncer de mama (sismama), 2009-2015

Abstract

Introduction: Breast cancer is the type of neoplasm with the highest incidence and mortality in the female population worldwide. Early detection of breast cancer is associated with incidence increase and mortality reduction. Objective: To analyze indicators of breast cancer screening from the records of mammograms performed in Brazilian women from June 2009 to July 2015. Method: Cross-sectional study with secondary data of the Breast Cancer Control Information System (Sismama) extracted from the records of mammography performed by the National Health System (SUS) in the female population between June 2009 and July 2015. The proportions of each variable were calculated to determine the selected indicators annually. Results: A total of 14,926,700 records of mammograms were analyzed, 96.8% of which were screening (MMGr) and 3.2%, diagnostic (MMGd). A little more than half of the MMGr (52.5%) were performed in the age group from 50 to 69 years, followed by the age group from 40 to 49 years (35.9%). There was a raising trend in the proportion of MMGr in the recommended range (50-69 years) in the period studied, in addition to a higher proportion of delivery of the test result in less than 30 days (both for MMGd and MMGr), with differences between the regions. Conclusion:Compliance with the Ministry of Health recommendations for early diagnosis of breast cancer is not uniform across the country. The necessity to develop health strategies addressing the existing inequalities among the country regions emerges.
