The concept of combining Chinese and Western medicine includes both Chinese medicine and Western medicine, not just taking Chinese medicine, and in the current field of tumor treatment, the role played by Chinese medicine is different with the different stages of tumors. In the initial treatment stage of tumor, the first thing that patients should consider is surgery and radiotherapy. At this stage, TCM treatment is in the auxiliary position. The treatment of tumor is based on radiotherapy and surgery, and cannot be based on purely Chinese medicine treatment. At this stage, the principle is to cooperate with TCM treatment on the basis of modern medical treatment. Therefore, TCM treatment is mainly to regulate the balance of the internal environment of the body, with the purpose of reducing the side effects brought by western medical treatment and improving its efficacy. Because the tumor load is smaller at this stage and radiotherapy and other means to kill tumor cells are being used, so TCM treatment is mainly aimed at adjusting the balance of the internal environment and should add less anti-tumor drugs such as toxic drastic drugs from TCM to avoid aggravating the damage on top of the damage caused by radiotherapy and chemotherapy to the human body. Some patients will have tumor recurrence after treatment. At this stage after recurrence, the tumor load in the patient’s body is relatively large, and the effect of Western medicine treatment is often poor again, so Chinese medicine treatment rises to a relatively major treatment status at this stage, and both Chinese and Western medicine need to be emphasized. Therefore, along with radiotherapy and chemotherapy, TCM treatment is mainly aimed at anti-tumor and adjusting the balance of internal environment. Accordingly, more toxic drugs are used in this stage of tumor treatment, and because tumor and treatment cause certain degree of damage to the body, so the support of the body is also used more in this stage. Stable stage: At this stage, most of the tumor cells have been killed by surgery and radiotherapy, and modern medicine lacks further treatment, and the body is in an imbalanced state. Therefore, in this stage, TCM treatment rises to the main position. At this stage, TCM treatment should firstly adjust the imbalance of internal environment caused by radiotherapy and surgery, and on this basis, certain TCM toxic drugs should be added to further kill the cancer cells remaining after western medicine treatment, so as to prolong the survival time of patients and even achieve the purpose of cure.
