Impacts of chronic disease on breast cervical and colorectal cancer screening in rural Oregon

Cancer screening reduces morbidity and mortality, yet rural populations face unique barriers. This study examined associations between chronic conditions and up-to-date screening for breast, cervical, and colorectal cancer among patients in four rural Oregon clinics (2008–2009). Chart review and logistic regression revealed that patients with three or more chronic conditions were less likely to be current, especially for cervical cancer (OR=0.40, 95% CI: 0.23–0.70). Condition-specific effects varied: cardiovascular disease and depression reduced screening likelihood, while digestive disorders increased it. Findings highlight the need for tailored interventions to improve screening adherence in rural primary care settings.
