Objective To explore the application effect of collage psychotherapy on fear of cancer recurrence in young breast cancer patients. Methods A total of 87 young breast cancer patients were divided into a control group（n=43）and an intervention group（n=44）chronologically. The control group received routine health education, while the intervention group additionally received collage psychotherapy. Before the intervention and 12 weeks after the intervention, the Fear of Progression Questionnaire-Short Form, the Hospital Anxiety and Depression Scale and the Herth Hope Index were used to assess the effect. Results Twelve weeks after the intervention, the score of fear of cancer recurrence, anxiety and depression in the intervention group were significantly lower than those in the control group, while the score of hope was significantly higher than that of the control group（P＜0.05, P＜0.01）. Conclusion Collage psychotherapy is conducive to alleviating the negative emotion of young breast cancer patients, and improving their hope level.
