Recently, someone in my WeChat circle of friends has been posting an article about the theory of Makoto Kondo, a so-called conscientious doctor in the medical field in Japan, and his book “Don’t fall for cancer again”, and I feel a lot of emotions after reading it. Of course, due to my poor writing skills, I often cannot write a good article with sharp words and quotations, and my popularization is limited to my friends, patients and colleagues. By forwarding some articles and excerpts from other people’s good science to insist on literacy. But often the effect is very little. Often, I am still asked by friends some questions that are seriously lack of logic or common sense, so science popularization is a long way to go. Some common sense about tumor, in fact, tumor is the original cells of our body have become malignant, tumor is the original cells of human body have changed, crazy growth, uncontrolled, and often like to invade other cells on the side. This may be simpler to say. As doctors, we often see a lot more malignant tumors than ordinary people, so sometimes some of our relatives and friends often have such questions after their relatives and friends have malignant tumors: First, they are afraid, thinking that this disease is not even cured and so terrible, will I or my relatives and loved ones get it? Secondly, they do not understand why they have it, because they have not studied statistics, so they often attribute it to some common possible factors, plus many false information and rumors flying around nowadays, which will lead people into a desperate situation of being on guard everywhere. However, this does not serve the purpose of preventing or curing tumors. So, what exactly causes tumors? Medical science is still not able to fully understand all the causative factors of tumors, but a lot of achievements have been made, not nothing like what Makoto Kondo said. In fact, if we calm down and think about it, what events in this world are caused by some very simple unilateral causes? Many natural, human, ideological and political events and phenomena are often the result of a combination of factors. In tumors, too, the genes of the tumor cells are altered, and the alteration is often the result of either internal or external factors. Some people may have mutations in their genes when their parents’ embryos synthesize a new set of genes, which is a very important way for human beings to adapt to the natural environment, but it is also possible that these mutations may have bad results, and some people may have even worse results, inheriting bad genes directly from their grandparents. Tumor research now has identified some fragments of genes that may cause cancer, and more will be discovered in the future. Genes are only one of the internal causes, but they are the most important. The exogenous factor is the gene that expresses the relevant protein to make the cell become different. In fact, I am afraid that our body will produce some bad cells every day. Fortunately, sometimes the body’s immune recognition system can identify and remove it, but as youthful years pass, the body cells will gradually age, and the immune cells will inevitably decline in function, and when more and more malignant cells are formed, malignant tumors will be formed. So. Many tumors occur in the elderly, AIDS patients are more likely to get some rare tumors, and some chemotherapy patients will also get another kind of tumor is this reason. So, what are the external causes? There are too many of them, the most common ones are radiation, radiation, which can damage people’s genes and cause some tumors, and at the same time, it will destroy the normal tissues of the body, and there is a possibility of some alien species in the process of repair. In fact, the most common external cause is damage, such as repeated burns, frictional injuries, repeated inflammation, damage in our body is the formation of a local inflammation, there will be exudation in the damaged area, there is redness and swelling is because of this, at the same time there will be a large number of new cells. If there are a few dishonest cells and they are not removed in time …… the penile cancer which was very common before is often due to the presence of such factors, as well as esophageal cancer, which may be related to the preference for hot food. Viruses or bacteria or fungi can also cause certain tumors, like cervical cancer in our gynecology, which is currently medically inclined to be caused by some higher types of human papillomavirus, nasopharyngeal cancer and EBV, stomach cancer and Helicobacter pylori, etc. In fact, many of our bad habits are not just habits, but these habits may lead to the occurrence of some injuries. For example, the incidence of gastric cancer is decreasing worldwide, do you know why? It is because of the invention of refrigerator, since then, we can eat fresh food, no longer need to eat pickled food, pickled food contains a lot of nitrosamine salt, which is a carcinogenic substance. The incidence of lung cancer in developing countries, such as our country has been rising, which is closely related to industrial pollution and smoking. Of course, different tumors may have some different causative factors. We can only talk about the common ones. So, should tumors be treated or not? That is, if you agree with my point above that tumor is a disease, can it be treated or not? In fact, I am afraid many people don’t know that through the continuous efforts and development of medicine, there are many malignant tumors that can be treated now. Some of them can even be cured. First of all, I do not deny that there are some, but the number is certainly very few, patients who have malignant tumors and the tumors will miraculously heal themselves. Because as I said earlier, our body is capable of doing so. As for whether the family members went to pray to God and worship Buddha or found which still living miracle doctor to eat the prescription and cured, because the number is really not much, it is not good to summarize, if it is spiritual, then it might as well be made public, so that all human beings can enjoy this wonderful treatment plan, right? Before talking about the treatment effect, we also have to distinguish the malignant tumors. Simply put, there are degrees of malignant tumors, some extremely malignant and some low malignant, just like our people, some are very strong and some are very weak. So, dear smart you should understand, this is the life that many people complain about! Because, if a person with a strong immune system has a tumor that is not too malignant, it should be possible to live longer than the time the tumor kills. So, since there is a difference between high and low, there will also be a difference between different stages, this is now more common knowledge. In a word, early stage malignant tumors are easier to control or even cure, but late stage ones are harder. Then, how to cure tumor? It is “early detection, early diagnosis and early treatment”. Early detection means to do some screening tests, such as cervical cancer, which can detect early HPV infection and pre-cancerous lesions, and it is possible to control them with proper treatment. Of course, not all cancers or other malignant tumors can be detected early. For example, our respiratory tract, intestine, urinary tract, genital tract, skin and abdominal cavity are all epithelial, and malignant tumors also include sarcoma, which is a tumor of bone called sarcoma, muscle tumor is also called sarcoma, and blood cell tumor is a kind of leukemia. Some tumors are hidden and not easy to detect until they reach a certain size, and they often do not have obvious symptoms. Sometimes doctors are not to blame for not finding them. Now, medical science has been trying to find ways to see if some specific indicators of tumors can be detected from the blood. Some of them are available, such as CA125 and HE4 for gynecological ovarian cancer, and PSA for prostate cancer, but there are still many malignant tumors that cannot be detected early by blood sampling. However, there are still many malignant tumors that cannot be detected early by blood sampling. With a certain volume of tumor, we have to rely on imaging, which is ultrasound, X-ray, CT, MRI and even PET. However, imaging can only detect the tumor, but it cannot determine the nature of the tumor, whether it is good or bad. This also depends on pathology, which requires taking the appropriate tissue cells and putting them under the microscope to carefully see if the structure has changed. Only after the diagnosis is confirmed can we start further treatment. As I said in the opening chapter, a malignant tumor is one in which our own cells become malignant, and it is often close to the surrounding cells. It is really troublesome to destroy it. First of all, surgery can remove the solid tumor, but only those visible to the naked eye, and those that are invisible to the naked eye have already sneaked out with the blood? Because it is difficult to find them, we can only kill them by injecting chemotherapy drugs into the blood or remove them by receiving controlled radiation within a certain dose. Whether it is surgery or chemoradiation, it hurts our body and causes many complications, side effects. This has led to the resistance and concern about the way of tumor treatment. Many statistics tell us that surgery and chemoradiotherapy still prolong the survival time of many patients with intermediate and advanced malignant tumors. These are already the mainstream understanding of medical science, and there is no way to deny them. The author of a recent article published by Southern Weekend, who has been to Japan for study, gives his opinion on what he knows about the background of Makoto Kondo, the so-called doctor, and the controversy he has caused in Japan. Here I would like to suggest that all of us should be more careful when we see some particularly bizarre, effective and affirmative propaganda, and learn more about the relevant background and knowledge, not necessarily for everyone to become a doctor, but at least not to be deceived, right? Many of these scams or pseudoscientific things actually often do not stand up to careful scrutiny and argumentation. And this need is only a rational understanding of the cruelty of the real world is enough!
