The last hundred years have been a century of rapid development in both natural and social sciences, and mankind has made many excellent achievements in understanding the objective world, and has gained some insights into the age-old mystery of cancer. After human beings have satisfied their food and clothing, health and quality of life are the greatest pursuit. At present, as most regions are in peaceful development, the natural life span of human is guaranteed to a great extent, and modern medical science and technology have strong control over the epidemic of infectious diseases, and the number of people dying from diseases such as war and infectious diseases is greatly reduced. However, cancer has become one of the most deadly chronic diseases prevalent among human beings. How do cancer cells arise? This is a very esoteric question, but with the current research in modern technology, there is some understanding of the formation of cancer cells. According to the materialistic view, life is a chemical process, and human beings are complex multicellular animals with advanced thinking abilities and the ability to use substances in the environment to perform advanced activities to satisfy their endless desires. But ultimately humans are made up of countless cells, and human diseases themselves and the length of life are ultimately determined by the biological nature of cells. The adult individual has about 50 trillion cells, and most human cells are spherical structures with a diameter of some 10 – 20 microns. The lifespan of cells varies: some white blood cells in the blood live only a few hours, intestinal mucosal cells live 3 days, liver cells live 500 days, and nerve cells live decades, almost equal to the lifespan of the human body. In the entire human body, 100 million cells die every minute. The human body cells are renewed every 2.4 years. Experimentally, it has been found that human cells can be cultured for an average of 50 generations under culture conditions, and each generation is equivalent to 2.4 years, which is called the Fleck factor, according to which the life expectancy of an average human being should be 2.4 x 50 = 120 years. The cell is a super complex machine, although the information recorded by chromosomes is the same in all somatic cells, there are different protein differentiation combinations at different developmental sites to form cells with different forms and functions. A cancerous cell is a type of cell that mutates during the ongoing development of the cell. It is conceivable that the huge chromosomal gene pool has numerous possibilities for errors, and the body has mechanisms to repair errors and to test for competent cells. However, during the metabolism of huge number of cells, due to the different stability of genes themselves and external stimuli, as well as environmental factors in the organism, eventually some cells eventually become cancerous and successful. They form with the possibility of clonogenic infinite increase in value, with the ability of migration movement. They can secrete destructive functional proteins and toxic factors. Originally, the immune cells of the body have the ability to recognize these carcinomas, but due to the clever camouflage ability of the cancer cells, it successfully evades the immune strikes and eventually forms subclinical lesions. After early proliferation, usually several years or even more than ten years, cancer cells undergo longer evolution, and cells with various abilities emerge within the cell population: some are highly reproductive and can reproduce indefinitely, some can not only reproduce indefinitely but also be motile, with golden bell-like ability to resist damage from chemical toxins and radiation damage, some have scud and cannot be chased by scalpel, and some have Some of them have the ability to hibernate and can hide in one place for a long time and then proliferate rapidly. In conclusion, cancer cells resemble a new individual with infinite possibilities, not governed by the host and not providing any beneficial functions to the host, but only infinitely acquiring the host’s nutrition, destroying the host’s inherent structure, and presenting a syndromic destructive power. In general, most tumors do not show strong destructive power in early stages, but develop slowly and insidiously. Once they reach a certain critical point of development, usually when they produce aggressive individual cells, they may have the potential for explosive growth. Although most cancers are a chronic process, there are indeed some cancers with explosive growth that can be fatal in a short period of time after the lesion enters the clinical stage, and most of them are not due to psychological factors of the patient. I saw a case of hypofractionated liver cancer that presented with systemic lymph node metastasis, similar to lymphoma, but this patient in his prime died quickly within two months of diagnosis from severe pneumonia due to immune failure. In contrast, some patients have a rather long course to rapid progression, even though asymptomatic lesions are clinically detectable. A businessman in his prime gave up further diagnosis and sought TCM treatment when a medical examination revealed a highly suspicious lung cancer occupancy in the lung. At that time, I guess the patient was afraid of cancer surgery. After a long latent period of about five years, a new tumor lesion was formed in the brain. The patient was finally diagnosed with brain metastasis of lung cancer due to weakness of limbs. Three years after the appearance of brain metastasis symptoms the patient eventually died of respiratory failure due to explosive dissemination of lesions in the lungs. There are also some fortunate cases of an elderly man who eventually underwent surgery for a lesion discovered five years ago and was postoperatively diagnosed with early stage lung adenocarcinoma. With cancer treatment, the best approach is to bring the cancer under control when it is an isolated lesion. If there are no contraindications to surgery or technical difficulties, surgical scalpel or ablative physical surgery is the best means. It can completely destroy the cancer cells within the lesion by mechanical and physical means. It is worth noting that there is a limitation of this treatment in that there are some cancers that do not occur in isolation, for example, many tumors have a significant percentage of multifocal characteristics, such as those of the gastrointestinal tract, urinary tract, and breast, and the multifocal origin makes it impossible to completely destroy the lesion with destructive local treatment, even if the cut margins are negative. In addition, there are cancers that are not isolated events and are highly related to the internal environment and genetic instability, with recurrent occurrence of several cancers. I have seen a rare case of four primary cancers: they occurred consecutively in less than a few years, but were all controlled by surgery or chemotherapy, and the quality of life is currently good, although it is not possible to predict how long one will live. For surgically inaccessible areas, such as the nasopharynx, there is a very high rate of failure and trauma, even when using uncovered surgery to open in. Surgery will not be better than radiation therapy, so radiation therapy is preferred as a treatment for nasopharyngeal cancer. When most of the recurrences in the radiation field after radiation therapy has failed are no longer tolerant of re-radiation therapy, surgery as an option can save a certain number of patients to get another chance for radical treatment. Radiation is also used to eliminate possible residual tumors. Surgery is influenced by the anatomical location and is unlikely to be complete for some locally spread lesions. Extended resection requires strict selection of indications to achieve better results. Radiation therapy can keep cancer cells under control for many years, even decades, and for some patients is theoretically curative. In general, a “recurrence” after 10 years is sometimes difficult to say that it is a recurrence, and many may be a second primary cancer. Chemotherapy is an effective treatment for systemic spread, and for sensitive cancer cells, chemotherapy can kill most of the cancer cells immersed in the chemical poison within a few hours. I have seen such results in patients with small cell lung cancer and breast cancer, where a 60 year old driver came in with a cough and chest tightness. If the cancer cells were allowed to multiply wildly, then he would soon die of respiratory failure. Within hours of the chemotherapy drug being injected into the bloodstream, the fragile cancer cells began to die and the cancerous tissue was in a state of melting. But chemotherapy is not realistic for most cancer cells to completely eradicate cancer. Because most cancer types are not particularly sensitive to chemical toxins, and even if they are, there are some insensitive and naturally resistant cells in the cancer cell community due to the heterogeneity of cancer cells. The cell is the most amazing material system in this world, which forms the basis of life. It is the emergence of higher beings like human beings that has shaped the present colorful appearance of human society. It is said that the nerve impulses of the nerve cells of the brain are transmitted at a speed of over 400 km/h, which is half the speed of an airplane. Cancer is just one of a vast array of cellular phenomena, or a reversion to ancestry. Whether human beings can control the life process of up to 50 trillion cells in our own body, it seems that our technology is still far from this level. Although we have begun to understand the structure of genes, it is only the beginning of understanding the phenomenon of life. Quantum medicine has emerged as a new medical concept for many years, and although it is still a difficult step, it has unintentionally expanded people’s understanding of the mystery of infinite life from the thinking and provided a new system view. The emergence of various medical concepts such as palliative medicine, evidence-based medicine, transparent medicine, and integrative medicine at least suggests that it is time for us, the self-proclaimed spirits of all things, to reflect. The cell is far from being as simple as most of us think, and our understanding of life is just beginning: the scientific research currently being done by countless scientists around the world is only a very peripheral part of the phenomenon of life.
