Introduction: Breast cancer in Brazil has high incidence and mortality rates despite the declining trend of mortality in some regions. Objective: To describe the trend of mammograms screening coverage in Brazilian macroregions and states and identify the influence of the national breast cancer control policies between 2010-2019. Method: The ratio of screening mammograms in the age group of 50-69 years per local of residence was calculated minus the population of health-insured residents in that age group and period. The trend was evaluated by the Joinpoint regression model. Results: Coverage raised in Brazil from 2010-2014 and declined from 2014-2019, with increase of the proportion of exams in the target population. This pattern was noticed in other regions, except the Midwest, but with different year of shifting trend. Two significant shifting points were identified in the country: from 2010-2014, with increasing trend (APC 8.7, 95%CI 6.2; 11.3), and from 2014-2019 with decreasing trend (APC -4.2, 95%CI -5.7; -2.7). The Northeast region was the only one with three points of shifting trend: from 2010-2012 (APC 30.3, 95%CI 22.9; 38.2), 2012-2017 (APC 4.7, 95%CI 3.0; 6.4) and 2017-2019 (APC -14.9, 95%CI -19.7; -9.8). No trend was identified for the Midwest region. Conclusion: There was an increase in the proportion of screening mammograms performed in the target population in the period for Brazil and macroregions, and a declining trend in mammograms coverage from 2014 onwards. These results indicate the priority given to the target population in the program of screening actions.
