Abstract
Gastric cancer, as a malignant tumor with high morbidity and mortality, poses a serious threat to people's health. The knowledge-attitude-practice (KAP) theory model shows important value in gastric cancer prevention by improving health knowledge, changing health attitudes or beliefs, and guiding healthy practice. At present, the application of this model in gastric cancer prevention has gradually received attention. This article reviews the current application status of the KAP theory model in gastric cancer prevention and analyzes the challenges, countermeasures, and development prospects in order to provide a reference for gastric cancer prevention.
