Implementation and initial outcomes of a breast cancer screening program in remote areas: a case study in the western Amazon, Brazil

Introduction:The objective of this study was to analyze the implementation of an opportunistic breast cancer screening program in the state of Acre (Western Amazon, Brazil) and assess its initial outcomes.Methods: Launched in July 2019, the program comprised a fixed unit and two mobile units targeting women aged 40-69 years.Quality control measures were rigorous.From 2020 to 2021, 17,680 mammograms were performed, with one-third by the mobile units.Results: A total of 64 breast cancer cases were detected, with 92.1% diagnosed at early stages (0, I, II), a significant improvement from the state's historical rate of 49. 9% (2000-2015). Conclusion:The program overcame access challenges by offering services closer to patients.Despite initial hurdles like staffing shortages and data management issues, the program demonstrated promising outcomes in screening uptake and cancer detection.Sustained efforts are crucial for enhancing effectiveness and ensuring equitable access to screening services.
