This study provides evidence on how ACP is understood and misinterpreted by cancer patients in a middle-income Latin American setting, an area that remains underrepresented in the literature. By demonstrating that misconceptions, cultural taboos, and systemic barriers operate through a reinforcing multilevel process, the findings offer a conceptual framework that explains why ACP remains marginal in routine oncology care. The model highlights critical points for intervention, including patient education, professional communication, and institutional support, and is directly applicable to similar sociocultural contexts characterized by strong family involvement and biomedical dominance. These results have clear implications, supporting the integration of ACP as a proactive, relational, and value-based process rather than a late end-of-life intervention.
