Introduction
As a disease with the highest incidence of malignant tumors in women, breast cancer poses a serious threat to the body function and life and health of patients [1]. The current clinical treatment measures for breast cancer include surgical treatment, radiotherapy, chemical drug treatment, etc., but they will cause side effects in different aspects and degrees to breast cancer patients, such as local tissue damage, tissue dysfunction, nausea and vomiting, etc.[2, 3]. In the process of receiving treatment, breast cancer patients not only need to bear the torment caused by the development of the disease and the treatment method, but also face pressure from various aspects such as economy, family, and work. Under these conditions, patients are prone to sleep disorders, negative emotions and other negative reactions [4]. Based on this, qualitative research on the self-management experience of breast cancer patients is extremely necessary, and the current treatment methods should be transformed from a single physical treatment method to a comprehensive treatment method that pays attention to the physiological and psychological needs of patients [5, 6]. This project will adopt the method of retrieval-related qualitative research combined with Meta integration, aiming to explore the real psychological needs and emotional experience of breast cancer patients, and provide a certain reference for formulating more applicable nursing measures.
