Chinese traditional medicine has a history and rich treasures. There are many records and descriptions about cancer tumor diagnosis, treatment and prevention in ancient medical books, which have formed a unique theoretical system. Practice has proven that the combination of Chinese and Western medicine has unique advantages and has achieved promising results in tumor prevention and treatment. Chinese and Western medicine are two medical treatment systems, each of which has made great contributions in history, but they have different characteristics in terms of disease understanding and diagnosis and treatment methods. If the two sets of treatment methods of Chinese and Western medicine can be organically combined and complement each other in specific clinical applications, it will surely benefit the majority of tumor patients. Western medicine clearly distinguishes between health and disease, while Chinese medicine believes that health is a balanced condition of the body, while disease is out of balance. Western medicine tends to transform the environment, while TCM focuses on adapting to the environment; Western medicine emphasizes the localized pathogenesis of organs, while TCM attaches importance to the whole, recognizes the conditions of disease occurrence, emphasizes the prevention of disease before it happens, and attaches importance to the adjustment of pathophysiology; Western medicine has better treatment methods for exogenous diseases, but lacks ideal methods for endogenous diseases. Western medicine has better treatment methods for exogenous diseases, but lacks ideal methods for endogenous diseases. In contrast, Chinese medicine attaches great importance to endogenous causes and recognizes that deficiency is an important internal cause of disease, and the doctrine of deficiency has been recognized by modern medicine. The theoretical basis of Chinese medicine for the treatment of tumors The theoretical basis of Chinese medicine is the yin and yang, the five elements, the internal organs and meridians, and the diagnosis and treatment, which is also the theoretical basis of Chinese medicine for the treatment of tumors. In the formation of tumor, there is always an imbalance of yin and yang, so it is said that tumor is only a local manifestation of systemic disease. 3.Basic rules for tumor treatment in TCM Under the guidance of the theory of positive and evil, yin and yang, qi and blood, and meridians of internal organs, there are four major methods in the experience of tumor treatment. These methods can be used alone or in combination with each other, such as combining blood circulation and blood stasis with Qi to strengthen the spleen, or adding heat-clearing and detoxifying drugs appropriately. The above four methods of treatment are generally not applied alone, but in conjunction with each other, and the prescriptions are not set in stone; they are used to the end, but are used in accordance with the evidence, and are chosen in response to changes in clinical symptoms. It is necessary to avoid piling up all “anti-cancer herbs” together in one big formula to cure the disease. 4. Experimental Research on Chinese Medicine Treatment The application of anti-cancer herbal medicine has been studied since the late 1950s, and a lot of clinical and experimental research on anti-cancer herbal medicine has been carried out in China. The effective anti-cancer components from Chinese herbal medicine have been studied in terms of pharmacological effects and toxic side effects, and they are chemotherapeutic agents such as hydroxycitric acid, trichothecene, onychomycin, paclitaxel, vincristine, arsenic and light powder preparations. Under the guidance of Chinese medicine theory on anti-cancer herbal medicine research, in clinical application, there are ophiopogon preparations, zanthoxylum preparations, toadstool preparations, stone garlic, bitter ginseng alkaloids, Hanfangqi, coix seed preparations, etc. Many achievements have been made in the screening of anti-cancer drugs in Chinese medicine. 5, the advantages of combining Chinese and Western medicine in the treatment of tumors Prevention and treatment of precancerous lesions: many tumors have precancerous lesions, such as esophageal epithelial cell hyperplasia and esophageal cancer; chronic atrophic gastritis (enteritis) and gastric cancer, there is a lot of information to confirm that effective treatment of precancerous lesions to stop their cancer is an important element of prevention. Traditional Chinese medicine has rich experience in preventing and treating precancerous lesions. For example, Liu Wei Di Huang Wan can improve the heavy proliferation of esophageal epithelial cells and bring down esophageal cancer. Improving cure rate and reducing toxic side effects: At present, there are 4 major methods of tumor treatment: surgery, chemotherapy, radiotherapy, immunization, and in our country, Chinese herbal medicine. The first three methods are all based on the destruction of cancer cells, and the evaluation of efficacy, which is determined by the regression of masses, has improved the cure rate. However, the trauma of surgery and the toxic side effects of chemotherapy and radiotherapy caused great pain to patients, and some were forced to discontinue their treatment. However, the combination of treatment with TCM has reduced the toxic side effects, and the course of anti-cancer treatment can be successfully completed, improving the efficacy, significantly improving the quality of life and prolonging the survival period. According to the statistics of more than 11,000 cancer patients who completed the course of chemotherapy and radiotherapy by combining Chinese and Western medicine, the completion rate of radiotherapy and chemotherapy was 70-90%; while the completion rate of chemotherapy and radiotherapy alone was 50-70%, and there was a statistical difference between the two groups. Prolonging patient’s survival: Surgery, radiotherapy and chemotherapy can destroy cancer cells, which is more damaging to patient’s organism, lowering immunity, prone to recurrence and metastasis. While traditional Chinese medicine can support and cultivate the root, it can improve the immune function of the body to prolong the survival period. Activating blood circulation and removing blood stasis improves the hypercoagulable state of blood, enhances blood circulation, reduces metastasis, stops recurrence and prolongs survival period naturally. Improve the quality of life and help patients to recover: After comprehensive treatment, mid- to late-stage tumors can prolong the survival period, and there are those who “survive with tumors”. Many patients’ quality of life has been significantly improved with the integrated treatment based on TCM. Promote the progress of drug innovation: With the combination of Chinese and Western medicine in the prevention and treatment of tumors, it has promoted the innovation of pharmacology, and now there are endless layers of Chinese medicine preparations for the treatment of tumors. For example: paclitaxel, pergolide class, ginseng one capsule, all extracted from botanical medicine class.
