A growing body of evidence-based medical evidence suggests that the lifestyle of breast cancer patients affects prognosis. Personal lifestyle-related factors such as dietary and nutritional status, weight change, physical activity status and smoking and alcohol consumption of breast cancer patients after diagnosis are associated with tumor metastasis recurrence, disease-free survival and morbidity and mortality. After obtaining long-term survival, breast cancer patients not only need long-term medical treatment and rehabilitation services, but also need to receive guidance on daily life to improve treatment outcomes and quality of life. The role of medical professionals is critical in guiding breast cancer patients to improve their lifestyles. Recommendations and guidance based on evidence-based medical evidence will play an important role in improving the quality of life, controlling symptoms and improving the overall health status of breast cancer patients. The Lifestyle Guidelines for Chinese Breast Cancer Patients, taking into account the characteristics of Chinese breast cancer patients, provide recommendations and suggestions for their daily lives regarding disease-free survival and long-term survival in stable disease, providing guidance for medical professionals, health service providers, breast cancer patients and their families. In conclusion, the disease-free survival of breast cancer patients is a favorable time to improve their lifestyle. The advice and recommendations in this guideline will help breast cancer patients to form healthy dietary habits, good physical activity habits, and achieve and maintain normal weight to promote overall health status, improve prognosis, and quality long-term survival.
