At present, the treatment mode of malignant tumors is comprehensive, multidisciplinary and personalized, and the treatment means include surgery, chemotherapy, radiotherapy, targeted therapy and TCM treatment. Among them, the important role of TCM in tumor treatment has been recognized by more and more patients, and some of them have fully felt the efficacy overlapping effect brought by combined Chinese and Western medicine treatment. There are five roles of Chinese medicine in tumor treatment. In different stages of tumor treatment, according to different conditions and physiques of patients, Chinese medicine plays different roles, throughout the whole process of treatment, and plays different roles. 1. Combination of Chinese medicine and surgery. Pre-operative treatment with TCM can improve patients’ general symptoms, create good conditions for surgery and ensure smooth operation; it can control the development of cancer to a certain extent and prevent the potential risk of metastasis. Postoperative treatment mostly injures qi and blood, Chinese medicine can be given to benefit qi and fix the surface, replenish qi and nourish blood, so that patients can recover from the damage caused by surgery as soon as possible to receive other treatments as soon as possible to increase the tumor cure rate and improve the quality of life. 2. Combination of Chinese medicine and radiotherapy. One is the sensitizing effect of radiotherapy. Certain blood-activating and stasis-transforming Chinese medicines can improve microcirculation, change the internal environment of tumor and eliminate “oxygen-depleted cells”, and enhance the sensitivity of cancer cells to radiation. Secondly, it can reduce the side effects of radiotherapy. Radiation therapy depletes the vital energy and injures the yin liquid, resulting in the injury of both qi and yin or internal heat due to yin deficiency. Taking drugs that benefit qi and nourish yin, nourish yin and clear heat can significantly prevent or reduce the above side effects. Thirdly, radiation protection effects. Fu Zheng, benefit Qi and nourish Blood, strengthen the spleen and kidney Chinese medicine can protect the bone marrow and immune function of patients, so that radiotherapy can be completed successfully. 3. Combination of Chinese medicine and chemotherapy. First, it has a potentiating effect. By improving the local blood and oxygen supply to tumor tissues, it promotes the G0 stage tumor cells to enter the proliferative stage, thus enhancing the killing power of chemotherapy drugs on tumor cells. The second is the toxicity reducing effect. Chinese medicine adopts methods of strengthening the spleen and stomach, lowering rebellion and stopping vomiting, nourishing liver and kidney, benefiting qi and nourishing blood, etc., which can obviously reduce toxic side effects such as gastrointestinal reactions, damage to heart, liver and kidney functions, suppression of bone marrow and immune function caused by chemotherapy. 4. Chinese medicine prevents tumor recurrence and metastasis. Prevention of recurrence and metastasis is the key to success or failure of tumor treatment. Most tumor patients enter into a “waiting” stage after surgery, chemotherapy and radiotherapy, Western medicine no longer carries out any treatment, but only requires regular review until tumor recurrence and metastasis, and then adopts corresponding treatment. This “waiting” stage is a good period for Chinese medicine to play its advantages. We emphasize the combination of overall treatment and local treatment, and the organic combination of disease identification treatment and evidence identification treatment, which will greatly reduce the chance of recurrence and metastasis of tumor patients and significantly extend their survival period. 5.Reverse precancerous lesions. For atrophic gastritis, liver cirrhosis, cystic hyperplasia of breast, cervical erosion, mucosal leukoplakia, chronic ulcerative colitis, etc., if Chinese medicine intervention is applied at an early stage, not only the symptoms can be significantly improved, but also the risk of cancer can be significantly reduced. Chinese medicine means can improve the quality of life of patients: Conditioning the physique with Chinese medicine: prescribing the corresponding prescriptions to relieve the corresponding symptoms through Chinese medicine diagnosis and treatment can improve the quality of life of patients. The nutritional status of patients should also be evaluated, and nutritional care and intake should be enhanced according to the evaluation results. The psychological status of patients can be evaluated through the psychological assessment scale, and patients who need intervention according to the results of the scale can be given Chinese herbal medicine to relieve liver and qi and professional psychological guidance. Rehabilitation physiotherapy to improve symptoms: Through acupuncture and massage, acupoint injection (patching), electrotherapy, magnetic therapy, exercise therapy, etc., the treatment of dysfunction, low function and related discomfort symptoms of tumor patients can improve the quality of life of patients. Chinese medicine rehabilitation physiotherapy mainly includes the following aspects: First, the recovery of body damage and function after tumor surgery, such as intestinal paralysis symptoms after gastrointestinal surgery, edema and activity limitation of the affected limbs after breast cancer surgery, and joint movement disorder after bone and soft tissue tumor surgery. The second is the management of adverse effects of radiotherapy, such as fatigue, nausea and vomiting, peripheral neuropathy caused by chemotherapy, dry mouth after radiotherapy for head and neck tumors, etc. Third is the application in tumor palliative treatment, such as cancer pain that is difficult to be relieved by common analgesic drugs. Fourth is to relieve tumor-related symptoms, such as anorexia, insomnia, anxiety, depression, etc.
