Objective:Identify factors related to the health system that lead to a late diagnosis of breast cancer in Brazil.Method:We performed a systematic review in the PubMed and LILACS databases using as keywords "Breast cancer," "system of health" and "Brazil or Brasil." We evaluated the content of the articles using the PRISMA methodology based on PICTOS. The final date was 12/16/2015. We were able to identify 94 publications in PubMed and 43 publications in LILACS. After assessing the title and summary, and excluding 21 repeated publications, we selected 51 publications for full evaluation. At this stage, we excluded 21 articles, with 30 publications remaining for study.Results:The population coverage is low, and there are problems related to the quality of mammography. Patients with lower income, nonwhite and less educated are more vulnerable. We observed punctual and initial experiences in breast cancer screening. Diagnosis and treatment flows must be improved. The inequality in mortality reflects the differences related to screening structure and treatment. Better results are observed in well-structured services.Conclusion:There are several barriers in the health system leading to advanced stage at diagnosis and limiting the survival outcomes. The establishment of a rapid and effective order for diagnosis and treatment, based on hierarchical flow, are important steps to be improved in the public health context.
