This study examined the relationship between online cancer forum use, attitudes toward complementary and alternative medicine (CAM), and the use of non-evidence-based therapies, with a specific focus on CAM approaches prevalent in German-speaking countries.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A cross-sectional anonymous online survey was conducted in June\u2013July 2025 among adult users of the largest German cancer forum, assessing forum use, CAM-related attitudes (defined according to the German S3 guideline checklist, version 1.2), eHealth literacy, psychological distress, and sociodemographic and disease-related variables.
