Background: Recent studies have found that knowledge about cancer prevention and treatment differs across ethnic and socioeconomic status (SES) backgrounds, which could directly impact our decisions to engage in protective health behaviors. In this study, we examined sociodemographic-based differences in cancer knowledge and health beliefs and examined differences in the accuracy of the cancer knowledge based on health beliefs.
Methods: Cross-sectional surveys were conducted between July 1995 and March 2004 on adult, healthy, cancer-free control participants (N = 2074; 50% male) enrolled into a molecular epidemiological case-control study.
