Bringing down the barriers to mammography: a review of current research and interventions.

Although mammography screening is effective in reducing breast cancer mortality, major challenges still remain in increasing rates of initial mammography and in improving subsequent adherence to mammography screening. Behavioral science theories offer insights into the potential for individual, organizational, community, and population-level interventions to address these challenges. In this review, we draw on social ecological approaches to health promotion to suggest a conceptual framework for such interventions. After discussing theories of who is and is not screened regularly, and why, we consider selected barriers to mammography and corresponding interventions to overcome them. We conclude with an illustration of the North Carolina Breast Cancer Screening Program (NC-BCSP), a series of interventions informed by the social ecological perspective.
