In fact, epidemiological data from all over the world and China show that the incidence and mortality of malignant tumors have increased significantly in China and other countries in the world (of course, each malignant tumor may be very different, and here is the overall trend of malignant tumors). Especially lung cancer, thyroid cancer, gastric cancer and so on, more and more people are diagnosed as malignant tumors, which seriously affect the quality of life of patients and even shorten their life span. So why are there more and more malignant tumors? Zhang Dafu concluded that it may be related to the following factors.
First, people's living environment is becoming more and more unnatural and pollution is getting heavier and heavier. Pollution may come from air pollution, water pollution, food pollution and so on. There is also the change of people's food spectrum is becoming less and less "natural", and all kinds of fried and even "artificial" foods are being consumed more and more. These factors, constantly stimulating the body, may accelerate gene mutation and increase the possibility of malignant tumors.
The second factor may be that the average life expectancy of our people is getting longer and longer. As we all know, malignant tumors mainly occur in the elderly, especially those over 60 years old. In the past, the average life expectancy of people was very short, and they may have died of war or infectious diseases or other reasons before the occurrence of malignant tumors! Therefore, the extension of life expectancy also gives the opportunity for malignant tumors to occur.
The third is the progress of medical technology. In the past, many patients did not know that they had a malignant tumor, and even if they died, they did not know that it was caused by a malignant tumor, because there was no correct diagnosis. Or some patients have already suffered from malignant tumors, but the patients did not feel any discomfort, and there was no physical examination at that time, so many malignant tumors were missed. Among them, thyroid cancer is the most obvious. Studies have shown that about 20% to 40% of patients died of other causes, and thyroid cancer was found at autopsy. At present, due to the progress and popularization of ultrasonic equipment and the enhancement of people's awareness of physical examination, more and more people are diagnosed with thyroid cancer at an early stage. So with the development of medical equipment, more malignant tumors are diagnosed.
These are some reasons that I think may not be comprehensive. I hope you can understand them.
Why does the tumor happen so fast? Tumors won't happen soon. People who didn't get cancer the day before yesterday won't get cancer today. Cancer doesn't happen overnight, it's not an acute disease, it doesn't happen in a few days or months. It takes a long time for a person to diagnose cancer from the initial cell canceration to the clinically diagnosable cancer. For example, someone smokes and starts smoking at the age of twenty. After the age of 40, you will enter a period of high incidence of cancer, and the probability of cancer will increase significantly. It doesn't mean that you will get cancer today after smoking several packs of cigarettes a few days ago.
I think what you mean is to express why there are more and more people with cancer now, and the increase is so rapid. It's not that the tumor happens quickly, it's two different things. In fact, to put it bluntly, why do more people get cancer now than before?
In fact, this issue continues to have popular science for the following reasons:
There are more carcinogens in the environment, such as air pollution, water pollution, soil pollution, food safety problems, smoking, alcoholism and so on. There are more physical, chemical and biological carcinogens than before, as well as the so-called modern lifestyle and eating habits ... these are all important factors leading to cancer, which is the first and most important reason.
Life expectancy is prolonged and the population is aging. As analyzed in the first paragraph, the occurrence of cancer is not "rapid". On the contrary, it is a chronic process that takes a long time. It is always said that people used to smoke and drink, but in the past, the average life expectancy of people was thirty or forty years old, and it was easy to get cancer when they died of other reasons, that is, they had no chance to get cancer. People who start smoking at the age of 20 may get cancer after 50 or 60, and they also start smoking at the age of 20. There are not a few people who didn't have a chance to get cancer before, but now they live to be 50 or 60 years old. Think about it.
With the improvement of medical level, more cancers have been diagnosed, and many cancers have been missed in the past (there are also missed diagnoses now, but less than before), or people in the past, due to limited conditions, were delayed when they got sick, did not go to the hospital, and died without knowing what disease it was.
Everyone pays more attention to health. Physical examination and early diagnosis and screening are also helpful to find more tumors. Of course, it is easier to exchange information now. You can also know that people who are not in the same place have cancer, especially celebrities. Various reports make you feel that there are many cancers. For example, there was a plane crash before, but there were few reports, so you thought the plane wouldn't crash. There are many reports now, and you feel that the plane seems to crash easily. Of course, this is not the main reason, but one of the influencing factors. The analysis should be comprehensive.
I am a medical heart carving dragon, I will answer! Now more and more people have tumors. Why does the tumor happen so fast?
It must be said that since the 2nd/kloc-0th century, there have been more and more people suffering from tumors, and the reasons are very complicated. As we know, the onset of tumor is actually related to two reasons. One is genetic factors, because everyone has proto-oncogenes in the body, which are normally suppressed and will not cause cancer in the body. However, if some factors lead to gene mutation, these proto-oncogenes will be activated, resulting in normal cells only dividing without apoptosis. The second is: environmental stimulus. Everyone must contact the external environment from birth. I'm talking about the broad environment, including all aspects of life. In the interaction with the environment, the body will be stimulated by various kinds, such as alcohol, tobacco, pollution, radiation and so on. These factors can also cause cell canceration.
Of course, the incidence of many cancers is not caused by a single cause, but is often the result of a combination of many factors. For example, a person over 40 years old has lung cancer, which may be related to his long-term smoking, but it may also be that his gene has mutated, and it is more likely that smoking has caused gene mutation.
The reason why modern people have frequent tumors is that I think it is related to environmental stimulation. Although the society is highly developed now, it is an industrialized society. In social operation, it is also accompanied by various harmful stimuli, such as food with various additives, air and soil pollution, and pressure to work late. These stimuli will seriously interfere with the normal operation of the body, and then induce cancer.
In fact, cancer is only the result of human aging, and people will always die. Cancer is just one of the most common causes of death. In other words, even if people don't have cancer, they will have other problems to end their lives.
Tumors are rich diseases. It means that people don't work when their living conditions are good, and they eat foods and drinks that are seriously out of nature and harmful to human health for a long time, resulting in low immunity. Over time, God of Wealth's illness will naturally come to you.
Of course, the disease of wealth is not only cancer, but also cardiovascular and cerebrovascular diseases, obesity, rabies and other new diseases that are divorced from nature.
These diseases are basically helpless in modern medicine, and human beings can effectively avoid them through their own practice. After all, our ancestors did not have these diseases. Below I introduce several measures that can effectively avoid the occurrence of rich diseases.
Don't eat toxic food, including food containing any chemical reagents and all drinks. Because all synthetic chemical reagents are harmful to human body.
Improve human immunity, including eating more natural plants and meat and contacting the soil as much as possible. Only organisms that grow in the natural environment can provide all kinds of secondary substances needed by human body, and artificial breeding and planting can hardly improve human immunity. Soil is the root of all things and can cure all diseases. If you don't touch the soil for a long time, your immunity will be very low.
Minimize close contact with all kinds of people outside Asia. This involves population competition, and biological exchange in different biogeographic distribution areas will lead to unpredictable diseases and the destruction of ecological balance, which will not be introduced in detail here.
Try to reduce pets, the most typical of which is pet dogs. Dogs can kill people, which is a matter of population competition. Simply put, with the increase of population density, dogs will reduce the number of human population in various unpredictable ways.
Don't drink milk, because it is not produced by real cows, which will accelerate the precocity of children and shorten their life span. Stay away from the world of chickens, if you don't want to get fat and precocious.
All health care products are deceptive. Eating too much will kill you.
Don't rely on vaccines. Vaccines are life-saving straws and can't guarantee that you won't get sick.
. . . .
The last point is to take part in manual labor in moderation. Labor is the essence that distinguishes man from other creatures. Labor creates human civilization and labor can change people's values. A man without manual labor is terrible. Labor can keep people away from these rich diseases.
I can't find a good Chinese doctor when I am sick. Looking for western medicine to eat western medicine can't cure the disease at all That's all that matters. Secondly, staying up too late is very bad for your health. These are dangerous things for tumors!
(Special answer for doctors and patients: Dr. Zhang from the Second Hospital of Tianjin Medical University)
With the improvement of modern living standards, the life span of human beings has been prolonged, and more and more people have been diagnosed with tumors around them, which has also led to the vigorous development of the insurance industry. So, why is the development of social tumors so rapid now?
There are many reasons. First of all, people's average life expectancy has been extended, followed by an aging population. As we know, most people with tumors are elderly people over 45 years old. Therefore, more and more people get tumors, and the types of tumors are also varied;
Second, with the improvement of living standards and medical technology, diseases that could not be diagnosed before can now be diagnosed as tumors or other diseases through various advanced means and testing equipment. Relatively speaking, the diagnosis rate of tumor has also improved;
Third, with the development of society and the process of urbanization, environmental pollution has followed, including (industrial pollution, automobile exhaust, smog formation) and so on. The living environment of human beings is not as good as before. Environmental pollution makes our diet, drinking water and air unsafe, which is also some inducement to lead to tumors.
Fourth, modern people are under great pressure and their lifestyles have changed greatly, such as long-term smoking, heavy drinking, obesity, staying up late, excessive intake of red meat, too little intake of fruits and vegetables, and too much intake of fast food, additives and preservatives. , can cause various cancers, such as lung cancer, laryngeal cancer, esophageal cancer and so on. Excessive drinking mainly causes digestive tract tumors such as liver cancer, esophageal cancer and gastric cancer, followed by breast cancer and lung cancer. Obesity is related to esophageal cancer, colorectal cancer, breast cancer and endometrial cancer. Staying up late, irregular living environment, decreased immunity and increased cancer risk; In diet, excessive intake of red meat may increase the risk of colorectal cancer. Coupled with the application of processing methods such as frying and barbecue, it can produce a variety of carcinogens. Food contains too many additives and preservatives, which will lead to various digestive system tumors. Reduced intake of fruits and vegetables may increase the risk of digestive tract tumors, because dietary fiber and various vitamin trace elements in fruits and vegetables are very helpful to prevent cell mutation or inhibit the proliferation of cancer cells;
Fifth, finally, modern people have too much pressure, less exercise, poor mentality, complaining when things happen, full of negative energy, and their body and mind are in a sub-health state for a long time, which is more likely to cause tumors. In addition, with the improvement of living conditions, people's health awareness is enhanced, and they will have regular physical examinations or go to the hospital if they feel slightly unwell. So from a certain point of view, the detection rate of tumors is increasing, and many of them may have been found at an early stage.
For each of us, preventing tumors is far more important than treating them. In order to prevent tumors in daily life, besides regular physical examination and early detection, we need to work and rest regularly, avoid some bad habits, rest on time, eat on time, eat more fruits and vegetables, drink more water, eat red meat in moderation, reduce processing methods such as frying and barbecue, reduce the intake of processed foods containing too many additives and preservatives, smoke less and drink less, exercise more, reduce unreasonable medication, and relieve stress in various ways to maintain a good mood.
First of all, why more and more people get tumors is actually an environmental problem plus a diet problem. I won't say much about environmental pollution. Many articles are introduced in detail. I mainly talk about diet.
At present, the staple foods we eat are basically rice and white flour. For traditional food crops such as beans, sweet potatoes, millet and corn, they are basically eaten as vegetables, or only occasionally for a change. Moreover, with the improvement of living standards, while the intake of vegetables is decreasing, cooking is more willing to put oil than before, and cooking has become commonplace. This will lead to two problems: 1. Insufficient intake of β-carotene, the precursor of vitamin A that can inhibit tumor growth (β-carotene is widely found in green leafy vegetables, beans, potatoes and yellow grains); 2. A large number of trans fatty acids are produced during cooking, and excessive intake leads to obesity, which will also increase the risk of cancer; If the frying temperature is too high, it will lead to scorch and produce a secondary carcinogen-acrylamide (frying or barbecue will even produce a large number of first-class carcinogen benzopyrene).
Therefore, as the saying goes, "cancer is eaten" is reasonable.
Secondly, why did the tumor happen so fast?
In fact, everyone's situation is different, and the situation of each tumor is different. According to different stages, the development speed of tumor will be different. This will lead to the rapid growth of tumors in some cases, which can increase a lot in a few months; The other three or five years have not increased. But why do ordinary people think it is developing rapidly? It is nothing more than that many people are usually in the middle and late stages after being discovered, which makes people feel that they are often caught off guard when they are discovered.
I want to say here that early cancer generally does not develop rapidly, and the treatment is simple and the prognosis is good. But why do many people find it late? It is because when there is no discomfort, they often don't pay attention to physical examination, and they don't necessarily have a physical examination every three to five years, but when there are symptoms of discomfort, they will think about it. However, when symptoms appear, the best treatment period is often missed.
Therefore, if conditions permit, regular physical examination must not be ignored, preferably once a year. For people over 45 years old, or people whose working environment is full of dust and chemicals, it is best to have a physical examination every six months. Early detection and early treatment are not so terrible.
1。 Nowadays, the average life expectancy of people has been greatly extended, and many older people died before they got cancer.
2。 Today's examination and diagnosis methods are much more advanced than in the past, and people who died of cancer in the past may not be diagnosed.
3。 The current environmental pollution and food safety problems have greatly strengthened the external carcinogenic factors.
4。 Modern people's social psychological pressure is too great, they cheat and live too tired, which contributes to the occurrence and development of cancer.
Tumor is an incurable disease known by western medicine. It doesn't matter if you check it out. The key is not to choose western medicine treatment. Otherwise, wouldn't it be sending sheep into the jaws of death? The only reliable and best way is to choose a private doctor for treatment, because most Chinese medicine practitioners sent by hospitals are half a bucket of water, which basically can't solve tumor diseases, and private doctors are suppressed by the crime of "illegal medical practice". There is no room for medical treatment of patients, and some even rest. In this era, it is difficult to find a Chinese doctor who can cure all kinds of strange and complicated diseases.
It is closely related to the living environment, such as food, shelter, breathing air, radiation of electronic products, irregular life and great pressure, which leads to low immunity and high incidence of cancer.
