Complementary Medicine Use and Uptake of Cancer Screening Among US Adults: A Nationally Representative Cross-Sectional Survey

Background: Cancer screenings can considerably reduce cancer mortality. There is limited information on the association between complementary medicine use and adherence to recommended cancer screenings. In this study, the potential associations between uptake of cancer screening and consultations with complementary medicine practitioners or mind-body medicine use are examined. Methods: This is a cross-sectional analysis of the 2017 National Health Interview Survey of a population-based sample (n = 26 742; response rate = 80.7%). Age- and sex-related risk groups for breast cancer (women 45 years and older), cervical cancer (women 21 years and older), and colorectal cancer (45 to 85 years) were analyzed in 2018. Prevalence of complementary medicine use in the past 12 months as well as prevalence of cancer screening uptake in the past 12 months were calculated. Results: At least one complementary medicine approach was used by 32.4% of participants. Controlling for sociodemographic and clinical variables, individuals who consulted a chiropractor or naturopath or who used mind-body medicine approaches were more likely to take up Pap smear test (odds ratio = 1.20-1.35), mammography (odds ratio = 1.22-1.38), and/or colorectal cancer screening (odds ratio = 1.18-1.37). Those consulting a homeopath were more likely to take up Pap smear test (odds ratio = 1.33). No association was found between consultations of practitioners of chelation therapy or traditional medicine and cancer screening uptake. Conclusion: Complementary medicine use seems to be associated with a better adherence to cancer screening. Individuals who consulted a chiropractor or naturopath or who used mind-body medicine approaches were more likely to take up the recommended screening.
