What is a tumor? It is very important to find out this point. To treat tumor, we must first know what it is. If we don’t know each other, if we don’t have a clear understanding of it, if we can’t grasp its outline, then it is very difficult to achieve good results in treating tumors. It is like a big family with good children and bad children, some bad children only need to be criticized and educated, some are so bad that they need to be reeducated through labor, and some are so serious that they need to be sentenced to death. Malignant tumor belongs to the kind that should be “death sentence”. Tumor is a piece of flesh in human body, we are not too clear when dealing with this piece of flesh, many people think it is a pity to give it a death sentence, but it is a bad piece of flesh, so we have to get rid of it. But in fact, the most important thing, how this piece of bad meat in the human body is formed? People don’t seem to care. If we only think about cutting off this “bad meat” without thinking about why it is formed, it is very difficult to inhibit the development of tumor. It’s like a law that doesn’t regulate, but simply shoots criminals who have made mistakes, that killing one is only one less, and there will be thousands of criminals in no time. Therefore, to know why mistakes are made and to eliminate the root cause of such situations is the solution to the problem. So why does a piece of “bad meat” form? It is a piece of “bad meat” on the human body, we can not remove the definite word “human body”, this piece of “bad meat” is the human body poor supervision caused. The other day I listened to the radio, talking about counter-terrorism, saying that terrorists must be cracked down on, must be eradicated, but the results, the more crackdown on the more serious, and finally people say that the most fundamental way to combat terrorism is to eliminate the polarization of rich and poor. This is a bit like the current radiotherapy, people have paid a lot, but the results are not as optimistic as people think. The same is true for the treatment of tumors. One must first understand the causes of tumor production so that it is possible to eradicate them. Chemotherapy drugs have not made much breakthrough in the past ten years, and many people are saying that chemotherapy drugs are now close to the end of the road, and radiotherapy is only the reform of some new equipment to follow up, and no big breakthrough has been made, and the cost of radiotherapy and chemotherapy is getting higher and higher, which makes the economic pressure of patients more and more, which we do not want to see. Since tumor generation has a great relationship with human body, what exactly is the relationship? First of all, the internal environment of human body is changed. Without the change of internal environment, it is difficult to form tumor. The microenvironment of western medicine is about the environment between cells, which focuses on tumor cells and ignores the organs and tissues on which tumor cells depend. Secondly, tumor development occurs because of the destruction of immune cells around the tumor, mainly cellular immunity, which makes the tumor grow and metastasize. What is the relationship between immune cells and our body? Lymph nodes are immune organs, and enlarged lymph nodes (metastasis) are often caused by spleen deficiency and phlegm-damp internal nodes. What are the causes of spleen deficiency and phlegm-dampness? It is mainly sweet food and cold products. Then there may be genetic mutation of tumor cells themselves. Therefore, tumor is caused by the combination of internal environment change, immune function reduction and some mutations of tumor cells themselves. What are the advantages of Chinese medicine in treating tumors? The main advantage is to change the internal environment of tumor, which can regulate the functions of related organs and tissues. At present, Western medicine has not invested much research work in this area. The advantage of TCM is also to enhance immunity. The so-called immunity in TCM is very much related to the lymph nodes. However, oral tonics change the cellular immunity and regulate the whole body, which is not very targeted, so the efficacy can only be poor, so the advantage is not too obvious. In fact, the external application of Chinese medicine and acupuncture can obviously enhance the local immune function of tumor. The deficiency of TCM is mainly local treatment is not enough! The first level is to pile up drugs, that is, to pile up a bunch of anti-tumor herbal medicines; the second is to take some supportive drugs with some anti-tumor drugs; the third is to discern the evidence, the evidence of tumor in Chinese medicine is not only the evidence of internal organs, but also should include the evidence of meridians, the evidence of Sanjiao, the evidence of membrane origin, etc. It is very important to recognize this point, otherwise it is difficult to achieve a deeper understanding of tumor. Otherwise, it is difficult to achieve a deeper understanding of tumor. For example, I describe the six meridians as like a vine with many melons on it, the vine is the meridians and the melons are the organs. In terms of treatment, we should not only apply herbal medicine externally, but also combine with acupuncture, qigong and channeling methods, which are very useful for the treatment of tumors. Therefore, we can’t waste one kind of treatment for tumor, we can’t rely on oral medicine alone to eliminate tumor, if there is, the possibility is very small and the efficiency is very low. However, if combined with local treatment, the efficiency of TCM in treating tumors will be greatly improved. At the same time, we always emphasize that Chinese medicine and Western medicine are not contradictory, and the effective combination of Chinese and Western medicine can maximize the fight against tumor. The effective combination of Chinese and Western medicine can maximize the fight against tumor. Both of them should not be neglected, let alone denigrate each other. Talking about the mechanism of tumor recurrence and metastasis is the same, I think this point is subject to negotiation. The mechanism of local recurrence is relatively easy, because it is often due to the deficiency of vital energy, stagnation of Qi, blood stagnation and phlegm blockage. The formation of this blockage is mostly due to the change of the tissue structure and the increase of pressure in the local tissues (target organs), which is often due to some bad habits and postures, which is not noticed by Western medicine and not even noticed by Chinese medicine. But this is exactly what we need to pay attention to. In addition, most of the distant metastasis is through blood circulation, under what circumstances can tumor cells spread easily through blood? Mostly, our diet is too salty or high fat diet, which makes the blood more viscous, and when it flows through the blocked target organs, the tumor cells are left behind and further develop into metastases. However, even if both of these points are present, metastasis does not necessarily occur because there is a more important third factor, which is long-term mental stimulation. For example, if we have long-term mental tension, “fear hurts the kidneys”, and the kidneys are related to mental tension, at the same time, long-term mental overstimulation will also be prone to gastrointestinal diseases, such as irritable bowel syndrome, which is related to the person’s long-term tension. “This is a theory that long-term mental tension and downward movement of qi will lead to stagnation of qi in the lower jiao area, which may produce metastases in the lower jiao area. It is important to recognize this point. Therefore, the formation of metastases is not due to a single factor, but mostly due to a combination of three factors: first, blockage of the target organ, second, increased blood viscosity, chronic salty or high-fat diet leading to poor blood flow, and third, some kind of long-term adverse mental stimulation, a close combination of the three, often prone to distant metastases. Recognizing this, we know to remind tumor patients that they need to moderate their diet, smooth their emotions and change their bad habits and posture.
