Objective This paper systematically reviews the influencing factors of affective symptoms and psychological rehabilitation strategies of young breast cancer survivors (aged 50 years and under), so as to meet their psychological rehabilitation needs and provide evidence-based basis for medical staff to formulate precise psychological rehabilitation strategies. Methods. The databases PubMed, Embase, Web of Science, and Cochrane Library were searched for research questions from 2012 to 2022. The literature was screened and evaluated, and the content analysis method was used to conduct a descriptive analysis of the results. Results. A total of 20 studies were included, including 11 cross-sectional studies, 7 randomized controlled trials, and 2 cohort studies. The common affective symptoms of young breast cancer survivors are anxiety, depression and fear, and the influencing factors include personal factors, disease factors, family factors and socioeconomic factors. Conclusions. The influencing factors of affective symptoms in young breast cancer survivors are diverse, and the psychological rehabilitation needs have their unique characteristics, which have not been fully studied. There is an urgent need to conduct high-quality research in this field. According to its influencing factors, psychological rehabilitation strategies need to be developed to maintain their family role and social roles.
