The mode of cancer treatment has transformed from the “three-legged tripod” of surgery, chemotherapy and radiotherapy to the fourth mode – comprehensive treatment. In addition to the above three therapeutic means, biological therapy plays an important role, among which immunotherapy has become more and more mature. When cancer patients use tumor-killing treatment (including surgery, radiotherapy and chemotherapy), while destroying or killing cancer cells, they tend to be “indistinguishable from the enemy”, and play a destructive and lethal role in immune function, and the commonly used western medicines to improve immune function are often expensive and have a single role. Chinese medicine has a wide range of effects, and has a two-way regulatory effect, not only to improve the low immune function, but also anti-tumor effect, and more and more have a variety of regulating functions. For tumor patients with common weakness, gastrointestinal dysfunction, low appetite, impaired liver and kidney function, endocrine disorders, etc., all have a certain therapeutic effect. It has no toxic side effects when taken for a long period of time, and is loved by the majority of cancer patients. Statistics show that more than 95% of cancer patients in China accept Chinese medicine more or less in the process of treatment, and it is very difficult to find patients who only accept pure Western medicine treatment. It is very difficult to find patients who only receive purely western treatment. Chinese medicine is simple and inexpensive, so cancer patients cannot be separated from Chinese medicine treatment.
