Combination of Chinese and Western medicine is a comprehensive tumor treatment model with Chinese characteristics. Long-term practice shows that the combination of Chinese and Western medicine is the best solution for tumor treatment at present, especially for patients with middle and late stage malignant tumors. Western medicine has stronger ability to kill and injure cancer cells and has better efficacy in the near future, but due to the toxic side effects of chemotherapy drugs, for most tumors, chemotherapy with Western medicine alone cannot improve the cure rate, prolong the survival period and improve the quality of life. Although TCM has a weaker ability to kill and injure cancer cells, and its recent efficacy is poor, TCM can improve the patient’s survival quality, prolong the survival period, and have better long-term effects. Organic combination of western medical treatment and TCM treatment can not only effectively kill tumor cells, but also improve patient’s immunity, improve survival quality, reduce toxic side effects of radiotherapy and chemotherapy, reduce recurrence rate and improve survival rate, etc. In general, the current combined treatment of Chinese and Western medicine for tumors should be complementary to each other. In terms of treatment, Western medicine has better effect in preventing and treating local lesions of tumor or functional disorders caused by mass compression, but often lacks effective treatment measures for pathophysiological changes caused by tumor. Chinese medicine mainly regulates the pathophysiological changes in the patient’s body, which cannot be achieved by western medicine at present. Therefore, the combination of Chinese and Western medicine has the dual function of treating local masses and regulating systemic pathophysiological changes, and the mechanism and theoretical basis of its efficacy are here. In our long-term clinical practice, we deeply appreciate the respective characteristics of Chinese and Western medicine in tumor treatment, and pay attention to give full play to their respective strengths to achieve very satisfactory results. According to modern scientific research, traditional Chinese medicine plays anti-cancer role through the following aspects: 1. Traditional Chinese medicine can induce apoptosis of tumor cells and make cancer cells die naturally. 2. 2. Chinese medicine can inhibit the enzymatic degradation of tumor cells and affect the invasion and metastasis of tumor cells. 3.Chinese medicines have the potential to inhibit tumor neovascularization and stop tumor formation. 4. Chinese medicine has the potential to reverse the multidrug resistance of tumor cells, and can enhance the efficacy when used in combination with chemotherapy drugs. Chinese medicine is generally used according to the results of identification, and the specific medication varies from person to person, and individualized treatment is carried out according to different disease stages, different physiques and different types of evidence. Through long-term rational comprehensive treatment, the chances of recurrence and metastasis can be greatly reduced, the quality of life can be significantly improved, and the survival period can be prolonged.
