The formation of malignant tumor still needs to start from “genes”. Nowadays, medical doctors believe that there are proto-oncogene and oncogene in human body, the proto-oncogene is in charge of cell division and proliferation, which is needed for human growth. In order to “control” it, there is also an “oncogene” in the human body. Normally, the original oncogene and the oncogene maintain a balance, but under the action of cancer-causing factors, the original oncogene becomes more powerful, while the oncogene becomes weaker, and the human tissue mutates and keeps growing. This proliferation is not regulated by the body at all, and the new tissues produced do not have the functions of normal tissues. Its main activity is to keep consuming the body’s resources, crowding the space, and dividing and proliferating more and more rapidly. If the process continues, it will collapse the human body. Moreover, unlike virus, tumor is not an invader outside the body, its composition is the same as normal tissues, so the body cannot recognize it and remove it immunologically. What are the cancer-causing factors? It is generally believed that the main factors include mental factors, genetic factors, lifestyle, certain chemical substances, etc. Multiple “keys” work together to start the “cancer program”; and the more “keys” there are, the greater the chance of starting it. Since the mutations that need to be accumulated involve many genes, the process of cancer formation is usually years to decades long. This process involves three components: (1) carcinogenic factors, (2) genetic changes, and (3) tissue mutations. Treatment also involves these three components. Surgery, chemotherapy and radiotherapy mainly target the mutated tissues, which is the most powerful way to eliminate the mutated tissues. However, it can’t do anything about the cancer-causing gene, in which chemo-radiotherapy as a new cancer-causing factor at the same time may aggravate the gene disorder. Some people may ask, if there is a way to remove the proto-oncogene, does it mean that the cancer-causing factor will not cause the mutation of the tissue? And the fact is that without the proto-oncogene, the body is unable to replenish the aging tissues, leading to faster death. My understanding of the development of malignant tumors from the perspective of Chinese medicine: There is no such term as “gene” in the system of Chinese medicine, but according to the role of gene in the living body, that is, the gene controls the basic structure and performance of life, we can consider the gene as part of the true essence of the human body. Genetic energy is divided into genetic yin and genetic yang. Genetic yin is a kind of “forming” energy, which gives birth to the form of our internal organs; genetic yang is a kind of “transforming” energy, which gives birth to the function of our internal organs. This is what the Inner Classic says: “Yang transforms Qi, Yin forms”. When the energy of Yuan-Yin and Yuan-Yang of the body is insufficient, Yuan-Yin can’t form the form of normal organs and tissues and grows uncontrollably; Yuan-Yang can’t form the function of normal organs and tissues, so that the normal function of the body is lost and thus the body loses control. Therefore, the origin of the formation of malignant tumor is the deficiency of yuan yin and yuan yang. How does this deficiency lead to? In addition to the deficiency of congenital endowment, the influence of the acquired nature is also crucial. The basic principle of “cold energy hurts yang and fire energy hurts yin” is the acquired injury. Take diet as an example, many people drink beer and cold drinks, eat barbecue and spicy; take living as an example, staying up late hurts yang, air pollution hurts yin; take emotion as an example, endless desires dissipate yang, worries and internal knots create fire and hurt yin …… Nowadays, there is a saying that “people with good health are prone to cancer, while those with weak health are fine. The weak ones are fine”. This saying is only a superficial phenomenon. This so-called good body is actually more chaotic inside the body, and yin and yang are already seriously out of balance, so that the body cannot be adjusted in the form of cold and fever and other diseases. People who are weak are only at a lower level of balance of yin and yang and are still able to regulate the organism through minor illnesses. From clinical observation, malignant tumors are formed with Yang deficiency and Yin knots inside, while Yin deficiency and Yang knots outside. Yang deficiency and yin knot refers to the formation of yin knot due to cold energy injuring yang and the inability of yang energy to push. Yin deficiency and yang nodes refer to the formation of dry nodes because fire energy injures yin and there is not enough water energy to transport and transform. In malignant tumor, this state of dry knot outside and yin knot inside forms the rejection of yin and yang. In order to break this rejection, we must start from true yin and true yang. The advantages and problems of modern medicine in treating malignant tumors: Modern medicine treats malignant tumors mainly with surgery, chemotherapy and radiotherapy. If early surgery can remove the diseased tissues cleanly, and at the same time patients can change their life style and psychological state as a result, most patients will have a good prognosis. Radiotherapy and chemotherapy are effective methods to destroy malignant tumor tissues with poison. However, for most of the tumors, radiotherapy and chemotherapy cannot completely destroy all the tumor cells, and if there is a suitable environment, they will resurface. Therefore, it is important to remember that radiotherapy should be “moderate”. What is “moderate”? It means that the body should not be broken down by chemotherapy and radiotherapy, because the excessive weakness of the body is one of the main reasons for the rapid growth of tumor cells or extensive metastasis. Another disadvantage of radiotherapy is that radiotherapy does not have the function of repairing genetic mutations and further affects the body as a cancer-causing factor. In my opinion, the focus of TCM in treating malignant tumors: In eliminating malignant tumor tissues with poison, TCM is not as effective as chemotherapy and radiotherapy in Western medicine. The main advantage of TCM is to treat the disease by adjusting the human body to restore its normal function, because “the best doctor is our body itself”. In the treatment of tumors, we can follow the “Yellow Emperor’s Classic of Internal Medicine – The Greatest Treatise on the Supreme Truth”: “Pungent and sweet is Yang, sour and bitter is Yin, salty is Yin, and light is Yang. The six are either collected or dispersed, or slowed or urgent, or moistened or dried, or soft or firm, to the benefit of the line, to regulate its qi, so that it is also flat” principle to identify the evidence to treat. The ultimate goal of this treatment is the restoration and integration of the true yin and true yang of the body. The problem is that patients with advanced disease no longer have the opportunity and time to accomplish this goal. At this time, through herbal treatment, the patient’s diseased internal organs and meridians are in a relative balance of yin and yang, while the metabolic level is relatively low, which helps to inhibit the growth of tumors and buy time for recovery. It should be pointed out that no drug can replenish the body’s YuanYin and YuanYang, which are generated in the balance of Yin and Yang of the body and the intermingling of Yin and Yang. In other words, Chinese medicine treatment is to provide the environment needed for the recovery of Yuan-Yin and Yuan-Yang, not a direct supplement. Therefore, the patient’s state of mind and condition becomes crucial to the prognosis of disease regression.
