Abstract Introduction: Understanding how communities access and engage with health information is essential for effective health communication. Health literacy—the ability to read, understand, and use healthcare information—plays a crucial role in making informed health decisions. With the rise of digital technologies, internet access and online engagement have become key tools for obtaining health information. However, variations in health literacy and digital engagement can limit some populations' ability to fully access these resources. This study examined health literacy, cancer information-seeking behaviors, internet access, and digital engagement among adults in the Mayo Clinic Comprehensive Cancer Center catchment areas to inform more effective and region-specific health communication strategies. Methods: This study focused on adult residents within the Mayo Clinic Comprehensive Cancer Center catchment areas, covering 75 counties across Arizona, Florida, and the Midwest (Minnesota, Wisconsin, and Iowa). Data were collected through partnerships with the University of Florida and Mayo Clinic Survey Research Centers, and the "Boots on the Ground" approach involving community health workers. Methods included phone calls, online submissions, and community outreach for an anonymous survey. Validated measures assessed health literacy, information access, and digital engagement. Descriptive analyses were performed using valid responses, excluding non-responses and "Prefer not to answer" options to ensure interpretive accuracy. Results: Data from 2,681 respondents highlighted consistent barriers to cancer prevention with regional differences. In Arizona, 42.6% of respondents need help reading medical materials, but only 3.1% reported lacking confidence in obtaining cancer-related information. In contrast, 63.1% felt very or completely confident in accessing cancer advice. The primary sources of health information were doctors (17.6%), internet searches (11.4%), and family (9.8%). In Florida, 38.4% need assistance, but only 2.7% lack confidence, and 68.2% feel very or completely confident. Doctors (18%) and internet searches (13.1%) were top sources. In the Midwest, 38.5% struggle with medical documents, and 3.1% reported lacking confidence, while 66.4% felt very or completely confident. Internet access is widespread across all regions, with smartphones being the dominant device. Daily internet use for communication, browsing, and engagement with health apps and social networks remains high. Conclusion: Although many respondents face challenges with reading health-related materials, most report high confidence in obtaining cancer information, suggesting a gap between functional health literacy and perceived ability to access information. The widespread use of mobile devices and near-universal internet access offers a valuable opportunity to enhance health communication through digital tools. These findings emphasize the importance of tailored digital outreach to bridge literacy gaps and ensure underserved populations can access reliable health information.
