According to traditional Chinese medicine, tumor is a systemic disease, which belongs to the category of illnesses with positive deficiency and positive decay. The causes of the disease are mainly external and internal. Externally, the disease is caused by the accumulation of evil and toxins such as the six sexes and food, and internally, the disease is caused by the disorder of the internal organs and meridians, and the loss of yin and yang qi and blood, which makes the positive qi weak. Under the action of external evil, the body forms qi depression, phlegm stagnation, blood stasis, accumulation of toxins, etc., and the deficiency of positive qi prompts evil toxins to gather into lumps for a long time to produce tumors. The principles of treatment are: supporting the righteousness and eliminating the evil, attacking and supplementing at the same time, and treating with evidence. Heat and fire toxin is one of the causes of malignant tumor. Some of them have direct or indirect effects on tumor cells in vivo or in vitro; some of them can also affect the endocrine system of the body and improve the immune function of the body. Such as enhancing the function of adrenal cortex, improving the function of macrophages or lymphocytes, these drugs have a wide range of antibacterial effects, anti-inflammatory, antipyretic, swelling and pus dispersal or neutralizing toxins. As these drugs can control other infections of inflammation around the tumor, to a certain extent, they also help to reduce the symptoms and control the development of tumor. 2.Blood activation and stopping stasis method Qi and blood are the material basis of human life activities, running in the organs, meridians, limbs and bones, lifting and entering smoothly without obstruction. Qi is the handsome of blood and blood is the mother of qi, such as qi depression, qi stagnation and qi gathering can condense blood into stasis and cause accumulation of lumps. The formula of activating blood circulation and removing blood stasis can promote metabolism, improve blood circulation, increase vascular permeability, soften connective tissue, relieve inflammation and pain, improve local hypoxia of solid tumors, and increase sensitivity to radiation tumors. Some drugs have the effects of enhancing albumin solubility and reducing fibrin stability, thus preventing and destroying fibrin coagulation around tumors and within cancer foci. By improving the microcirculation of tumor tissues and increasing blood flow, anti-cancer drugs and immune lymph node cells can reach the tumor site to play anti-cancer effects, and can improve the level of the organism and enhance the immunity of the organism, thus helping to reduce symptoms and eliminate lumps. The concept of phlegm in Chinese medicine is wide, chivalrous phlegm refers to coughing and coughing out phlegm, but broad phlegm includes not only tangible phlegm but also invisible phlegm, which is one of the pathogenic factors of many diseases. Tumors are also related to phlegm stagnation, so the treatment should be to soften phlegm and remove phlegm to disperse the knots. Most of the phlegm removing drugs have different degrees of efficacy in suppressing and killing tumor cells, and are good at dispersing cysts and benign tumors, and may also have the effect of reducing or controlling inflammatory secretions around malignant tumors. 4.Dissipate and break up the accumulation method Tumor is manifested as accumulation of obstruction in the body. It can remove the stagnation, push out the stagnation and dissipate the mass. This method is applicable to all kinds of tumors, those with obvious masses in the early and middle stages, strong and solid forms, and those who are not yet deficient in qi. 5.Supporting the righteousness and replenishing the deficiency method “When the righteousness is stored inside, evil cannot dry up”. To support the righteousness and cultivate the essence is to support the righteousness of the body and regulate the imbalance of yin and yang, qi and blood; it can improve the patient’s ability to resist tumors and control their development. Supporting the righteousness and cultivating the essence is related to enhancing or adjusting the immune function of the body. It has a promoting effect on cellular immunity, humoral immunity, and it can adjust the function of pituitary-adrenal system and increase the content of cyclic squamate adenosine in cells. It regulates the ratio of cyclic adenosine squamate to cyclic ursine phosphate, thus inhibiting tumor growth.
