Among the factors affecting breast cancer recurrence and metastasis, some of them cannot be changed, such as pathological stage, malignancy degree and biological characteristics of tumor, but most of them can be changed, such as omission of treatment items, inadequate treatment, diet and nutrition, behavior and psychology, body internal environment index system and so on. If there are undesirable factors that contribute to tumor recurrence and metastasis among the modifiable factors, intervention and conditioning for these factors can effectively prevent breast cancer recurrence and metastasis by transforming them into good factors that can prevent recurrence and metastasis. To establish the method of preventing breast cancer recurrence and metastasis for patients, the following steps need to be done step by step. Step 1 Recurrence and metastasis risk assessment: In layman’s terms, this means understanding what good factors (factors that can prevent recurrence and metastasis) you have. What are the bad factors (factors that can contribute to recurrence and metastasis). To do this step well, first of all, a professional doctor needs to analyze all the patient’s past disease data to find out the good factors and bad factors; then he or she also needs to sort out the patient’s current life behavior and diet to clarify which factors are good and which factors are bad. Finally, a comprehensive physical examination should be done to identify the good factors (indicators) and bad factors (indicators). The purpose of identifying these factors is to determine the likelihood of recurrence and metastasis, and to develop a targeted program of measures to prevent recurrence and metastasis based on these factors. Step 2 Under the guidance of professional doctors, intervention and control measures are formulated for the identification of bad factors (indicators), generally speaking, intervention and control measures are as follows: 1. TCM methods for consolidation treatment. 2.Formation of favorable dietary structure Based on the assessment of dietary habits before and after the onset of the disease, adjustments and guidance recommendations are given to form a dietary structure that is conducive to the prevention of recurrence and metastasis. 3.Establishment of healthy behaviors Provide guidance and suggestions on behavioral patterns that are suitable for individual conditions, conducive to disease recovery and prevention of recurrence and metastasis in physical exercise, home life and social activities. 4.Establishing a positive mindset In response to the specific situation of individuals, we will adopt various methods of psychological intervention to jointly establish a positive belief and a stable mindset to overcome the disease. 5.Monitoring of internal body environment indicators Regular monitoring and evaluation of various internal body environment indicators that have an impact on disease development. 6.Adjustment of abnormal indicators of the body’s internal environment The abnormal indicators found in the monitoring will be treated with lifestyle adjustment and Chinese and Western medicine. Step 3 Under the guidance of professional doctors, implement the measures according to the formulated plan carefully, and regularly evaluate and adjust the measures according to the monitoring results.
