People often ask when to take traditional Chinese medicine when they have tumor. In fact, Chinese medicine should be taken at any stage of tumor treatment, only the purpose of taking Chinese medicine is different. Chinese medicine and western medicine give full play to their advantages and cooperate with each other, each taking its own strengths and avoiding its weaknesses, so as to form a comprehensive treatment plan that can benefit patients from the treatment to the greatest extent. Chinese medicine plays different therapeutic roles in different stages of tumor through different drug formulations. 1.TCM combined with radiotherapy Radiotherapy has always occupied an important position in tumor treatment, but radiotherapy, while fighting against tumor, will affect the digestive function and damage the spleen and stomach, causing patients to experience nausea and vomiting, and can affect the operation of qi and blood causing dizziness and fatigue, as well as causing damage to liver function and decrease in immunity of the body. The use of Chinese medicine in radiotherapy reduces the side effects of radiotherapy and ensures the smooth implementation of radiotherapy. Chinese medicine can regulate the function of spleen and stomach, improve sleep, protect bone marrow, enhance physical strength and improve immunity, which can enhance the treatment effect. 2. Chinese medicine combined with surgery Surgery is effective for eradication of most early tumor lesions, but it is more traumatic, and due to the spread of tumor metastasis, radiotherapy treatment is still needed after surgery to consolidate the efficacy or treat metastasis. The trauma of surgery and the adverse effects of radiotherapy make many patients suffer a lot in the treatment, and some of them cannot continue the treatment. At this time, the comprehensive conditioning of Chinese medicine can play a very important role. Before surgery, Chinese medicine is used to support the righteousness, improve the nutritional status of patients, enhance the physical constitution, and lay the foundation for surgery; after surgery, Chinese medicine is taken to regulate the spleen and stomach, nourish yin and produce fluid, improve the quality of life, and promote the recovery of the body. 3.Inhibit tumor recurrence and metastasis According to Chinese medicine, the key to tumor recurrence and metastasis is “positive not suppressing evil”, after surgery, radiotherapy and other treatments, it is not guaranteed that all the tumors in the body are removed. Therefore, during the recovery period of tumor patients, the tumor will not be able to develop. Therefore, during the recovery period of tumor patients, the dialectical use of Chinese medicine can help to eliminate the evil and resist tumor recurrence and metastasis. Even patients with some residual tumor lesions can still survive with tumor for a long time and have a good quality of life. 4.Late stage patients, improve the quality of life Many late stage patients, due to the serious imbalance of yin and yang of the internal organs, cannot tolerate further radiotherapy, at this time, patients can still use Chinese medicine treatment. According to the different purposes that need to be achieved in different treatment periods, TCM treatment for tumors takes patients as the main body and uses a holistic view and discriminatory treatment system to flexibly form prescriptions and use drugs, which has the advantages of good individualization, less toxic side effects, good efficacy and low price.
