In tumor treatment, it is found that complete eradication of local tumor often does not benefit patients more, and patients often suffer from distant spread and metastasis due to severe trauma of immune function, which greatly reduces the quality of life and survival. Biological immunotherapy has become the fourth major therapeutic measure for tumors after surgery, radiotherapy and chemotherapy. It stimulates and utilizes the body’s immune response to antagonize tumor cells, regulates and balances the body’s immune function, differentiates and inhibits the growth of tumor cells, and has the effect of selectively killing tumor cells. It should be said that bio-immunotherapy originated from traditional Chinese medicine, and the name of “tumor” was already found in the oracle bone inscriptions at Yin Ruins as early as the Zhou Dynasty, more than a thousand years BC. “It is the basic theory of Chinese medicine to understand the mechanism of disease (tumor) occurrence. The “Spiritual Pivot – The Beginning of All Diseases” says that “the deficient evil in the people also ……, stay and not go, rest and become accumulation, or in the Sun Loop, or in the transmission vein, or in the Fuchong vein, or in the brawn, or in the collection of the gastrointestinal tissues, and on the slow tendons, the overflow of the evil qi is incomparable”, indicating that The pathogenesis of tumor occurrence, development and metastasis is fundamentally due to the deficiency of positive qi, the declining function of the internal organs, the imbalance of qi, blood, yin and yang, and the disease from superficial to deep, resulting in “evil qi overflowing with lust” and multiple changes of evidence. In terms of treatment, we advocate the view that “nourishing the righteousness will remove itself”, and through adjusting the functions of the internal organs, yin and yang, qi and blood, and meridians, we can effectively prevent the occurrence, development and metastasis of tumors, improve the clinical symptoms of tumor patients, and improve the quality of life. It also improves clinical symptoms and quality of life. This holistic treatment concept of corrective therapy can be said to be the origin and essence of tumor bioimmunotherapy. There are many methods to help the tumor, but in general, it is only to balance the qi, blood, yin and yang, and regulate the function of internal organs. According to the theory of “kidney is the foundation of the first day” and “spleen is the foundation of the second day”, it is especially important to cultivate the spleen and kidney. Fu Zheng therapy is an important part of the comprehensive treatment of malignant tumors, and can provide more specific and personalized treatment plans by combining the physical differences of each tumor patient, modern medical treatment, and the degree of tissue and organ damage, and can be used throughout the whole process of modern medical treatment of tumors.
