Chinese medicine has a long history of treating diseases in China, and since it has considerable efficacy in cancer treatment and can make up for the deficiencies of Western medicine in many aspects, it is very commonly used in clinical practice. It can significantly improve patients’ quality of life, clinical symptoms as well as shrink or even disappear tumors to a certain extent. Chinese medicine can reduce the toxicity and increase the effect of radiotherapy. The use of Chinese medicine to prevent and control the toxic and side effects of radiotherapy and chemotherapy in tumor patients is one of the major features of Chinese medicine in the treatment of tumors, which not only can complete the course of treatment successfully, but also has the obvious effect of reducing the toxicity and increasing the effect of radiotherapy, and can also prolong the survival period of tumor patients. As a part of comprehensive treatment, Chinese medicine is applied simultaneously with surgical treatment, radiotherapy, chemotherapy, etc. Its purpose is to alleviate the adverse reactions of radiotherapy and chemotherapy, so that the patients can complete the course of treatment smoothly, and the application of traditional Chinese medicine after surgical treatment, radiotherapy and chemotherapy aims to improve the long-term therapeutic effect. The use of traditional Chinese medicine before surgery is to prepare for the resection of the surgery, which can improve the function of certain organs of the patient, as well as to improve the patient’s physical condition. Postoperative use of TCM is aimed at restoring the patient’s physical condition, improving or reducing postoperative adverse effects, trying to avoid or reduce metastasis and recurrence, and improving long-term efficacy. Giving evidence-based medication for the different symptoms that occur during radiotherapy can reduce the adverse effects of radiotherapy. Taking traditional Chinese medicine after radiotherapy can improve long-term efficacy and reduce recurrence and metastasis. Taking Chinese medicine during chemotherapy can reduce the adverse effects of chemotherapy, such as digestive reactions, commonly used to support the main drugs, such as qi. The use of Chinese medicine during the interval of chemotherapy can improve the patient’s physical condition and prepare for the next chemotherapy. The main purpose of taking Chinese medicine after chemotherapy is to improve the long-term therapeutic effect. For cancer patients who are not suitable for surgical treatment, radiotherapy or chemotherapy, traditional Chinese medicine is used as the main treatment method with the aim of controlling the cancer as far as possible while improving the symptoms and quality of life. For certain terminal cancer patients, the main purpose of using Chinese medicine is to alleviate symptoms and improve the quality of survival to a certain extent. Chinese medicine can also be combined with immunotherapy. Chinese medicine itself has the effect of improving the function of immunity, and its combined application with immunosuppressants can significantly improve the efficacy of treatment. In addition, CIK biotherapy is the fourth major tumor treatment technology after surgery, radiotherapy and chemotherapy. It follows the operation law of human body, the treatment process does not have any toxic side effects on human body, and it fights, inhibits and kills cancer cells by stimulating the immune response of the body. Different from traditional treatment methods, it mainly mobilizes the natural anti-cancer ability of the human body to restore the balance of the body’s immune environment, which can enhance the body’s immunity at the same time of killing cancer cells, and has a very good effect on inhibiting the spread of tumors and preventing the development of complications. This complements the advantages of Chinese medicine in treating tumors. According to Chinese medicine, the occurrence of tumors always belongs to the “deficiency of the root cause”, and the “internal deficiency of positive qi” as an important basis for the development of tumors runs through the whole process of the disease, and creates favorable conditions for the recurrence and dissemination of tumors. The combination of Chinese medicine and CIK technology can simultaneously bring into play the advantages of Chinese medicine in regulating the whole body, supporting the positive energy and suppressing the tumor, slowing down the metastasis and recurrence, and synergistically achieve the purpose of enhancing immunity, improving the quality of life of the patients and prolonging the survival period. Therefore, Chinese medicine can be used throughout the process of tumor treatment and has no obvious toxic side effects. However, patients should not rely solely on Chinese medicine treatment. For tumors that can be surgically resected and those that can be treated with radiotherapy and chemotherapy with obvious effects, Chinese medicine should be used together with the above treatments and comprehensive treatment should be adopted in order to get cured at the earliest possible time.
