I. Balance theory and the occurrence and development of diseases: Chinese medicine theory believes that the basic pathogenesis of any disease belongs to the imbalance of yin and yang in the body. If the balance is maintained so that the internal environment of the organism remains relatively stable (internal homeostasis), the organism will be in a healthy state. On the contrary, if the balance is out of balance and the internal environment of the organism is disturbed, the organism will undergo pathological changes, leading to diseases and even death. The development and metastasis of tumor are caused by many imbalances (such as imbalance between oncogenes and oncogenes, imbalance between cell proliferation and differentiation, imbalance between cell proliferation and apoptosis, imbalance between pro-metastatic factors and anti-metastatic factors, imbalance between host body immunity and tumor aggressiveness, etc.). The “imbalance” in the process of anti-tumor treatment: Surgery, radiotherapy and chemotherapy used in traditional treatment of tumors, while killing tumors, also hurt the body’s vital energy. As a result, the treatment often cannot restore the “equilibrium state” of the body, but sometimes aggravates the imbalance of the body. Clinically, it is common to see low immune function, gastrointestinal disorder, and aggravation of Qi deficiency and blood stasis, which create new imbalance. IV. Principles of comprehensive tumor treatment under the guidance of balance theory: The purpose of treatment is to regulate yin and yang and bring them back to balance. A reasonable comprehensive treatment mode is to adopt low-invasive surgical treatment while eradicating the tumor, together with the necessary reasonable dose of radiotherapy, and on the premise of balancing yin and yang, and on the basis of the combination of disease identification and evidence identification, to formulate corresponding treatment rules to support the righteousness and dispel the evil, to maintain the relative stability of the internal environment of the body, to establish a new state of equilibrium, to inhibit the growth of tumor to the maximum, and at the same time to protect the righteousness of the body, to improve It also protects the body’s vital energy, improves the patient’s symptoms, improves the quality of survival and prolongs the survival period. V. The role of Chinese medicine treatment in comprehensive tumor treatment: It is pointed out that in ① low grade malignant tumors ② treatment of residual tumors ③ elderly and physically weak patients as well as patients with major organ insufficiency such as liver and kidney ④ as postoperative treatment of tumors with low risk of recurrence and metastasis ⑤ adjuvant treatment of advanced patients and ⑥ combined treatment of Chinese medicine and surgery, Chinese medicine and radiotherapy in order to reduce toxicity and increase effectiveness.
