ABSTRACT

Objective:

to assess the implementation of actions for early detection of breast cancer in Primary Care and to verify the adequacy of these actions with the Ministry of Health recommendations.

Method:

a cross-sectional study conducted from September 2017 to March 2018 with 736 women registered in Basic Health Units in two municipalities in Acre. For data collection, a validated questionnaire was used. In statistical analysis, the chi-square test or Fisher’s exact test was applied.

Results:

the frequency of mammography was 42%. Of the women at standard risk for breast cancer, only 5,8% underwent mammography properly.

Conclusion:

there was a low compliance of early detection actions to the Ministry of Health recommendations; thus, the need to adopt measures to increase professionals’ adherence to government proposals is highlighted, as well as continuous actions assessments.
