Our group found that a healthy lifestyle may have a positive effect on preventing cancer. In order to further study, we have studied the causes of cancer, the treatment methods of cancer and the prevention methods of daily cancer. Discuss healthy lifestyle with them, so as to study the positive role of healthy lifestyle in cancer prevention.

Every year, we hear that the number of people suffering from cancer is on the rise. Big Ben died of nasopharyngeal carcinoma. But judging from his life, his old age was relatively healthy, so his cancer was cured. But due to a sudden relapse, Big Ben died. So can a healthy lifestyle prevent cancer? In order to understand this, we must first understand the causes of cancer.

Cancer is a common disease. Cancer can occur in all parts of the human body except hair and nails. Middle age is the peak of cancer. Among the death causes of middle-aged people, cancer accounts for 1/5. The average age of cancer patients is 55-59 years old, which is shorter than that of normal people 12- 18 years old. Cancer is a new heterosexual organism, which is automatically propagated by somatic cells. It comes from a single cell. This new creature is composed of a group of cancer cells that do not develop freely with physiological needs. Cancer cells have no function as normal cells. Because of its rapid and irregular growth, it not only consumes a lot of nutrients, but also destroys the organizational structure and function of normal organs. Tumor cells continue to divide and form new tumor cells, which infiltrate and spread from the primary site to the surrounding tissues. If this diffusion can't be controlled, it will further invade important organs and lead to failure, and eventually lead to death. . The transformation of normal cells into tumor cells has gone through a multi-stage process, usually from precancerous lesions to malignant tumors. These changes are the result of the interaction of a person's genetic factors and three external factors, including:

Physical carcinogens, such as ultraviolet rays and ionizing radiation;

Chemical carcinogens, such as asbestos, tobacco smoke components, aflatoxin (a food pollutant) and arsenic (a drinking water pollutant);

Biological carcinogens, such as infections caused by certain viruses, bacteria or parasites.

Aging is another basic factor in the formation of cancer. With the increase of age, the incidence of cancer increases obviously, which is probably due to the accumulation of specific cancer risk factors in the course of life, and with the gradual aging of a person, the effectiveness of cell repair mechanism tends to decline.

Exposure to some chemicals for occupational and environmental reasons can lead to tumors in different parts. Such as lung cancer (asbestos), bladder cancer (aniline dye) and leukemia (benzene). Some infectious diseases are also closely related to some cancers, such as hepatitis B virus and liver cancer, human papillomavirus and cervical cancer. In some countries, parasitic infection of Schistosoma japonicum will significantly increase the risk of bladder cancer. Exposure to some ion rays and a lot of ultraviolet rays, especially ultraviolet rays from the sun, can also lead to some tumors, especially skin cancer. Commonly used cancer-causing drugs are sex hormones-estrogen and androgen, and tamoxifen, an anti-estrogen drug. Estrogen widely used by postmenopausal women is related to endometrial cancer and breast cancer.

Relevant research shows that it is only possible to cure cancer in the prophase and metaphase, and at the same time, the risk and cost of treating cancer are high, and patients need to bear huge psychological burden and pain. This will leave a shadow on the patient's future life journey. Therefore, doctors advocate preventing cancer in daily life. We found the following thirteen ways to prevent cancer.

First, quit smoking and prevent cancer: many chemical components and radioactive elements in smoke can cause cancer.

Opening windows to prevent cancer: surface and many building materials will release carcinogenic gas-radon and its daughters. Opening windows can minimize the density of such carcinogens in indoor air.

Second, optimistic cancer prevention: nervousness, depression and pessimism will seriously inhibit the immune function of the body and help cancer cells take advantage of it. On the contrary, optimism and cheerfulness can show great inhibitory effect on cancer cells.

Changing eating habits to prevent cancer: The research results show that constant eating habits will lead to a variety of cancers, so foods should be diversified.

Third, physical examination and cancer prevention: multiple tumors are gradually evolved from some chronic diseases. Early intervention can be achieved through regular physical examination. Timely and effective treatment can not only remove precancerous lesions, but also completely cure some early tumors.

Fourth, rubbing the back to prevent cancer: there is a layer of tissue under the skin, usually in a dormant state. When rubbing the skin with a towel, the stimulated tissue cells will become active, enter the blood circulation and gradually develop into reticular cells. Reticular cells have immune function. Therefore, rubbing your back often can enhance your immunity and get the effect of preventing cancer.

Five, saliva cancer prevention: the peroxide in the liquid has a special effect of inhibiting carcinogens. It is suggested to "chew 30 times a meal" to give full play to the role of saliva and improve self-care ability.

Six, drinking tea to prevent cancer: leaves can block the synthesis of nitrosamines, a carcinogen in the body, and at the same time, it also has the effect of inhibiting nitrosamines from causing cancer.

Seven, sleep cancer prevention: cells are abnormal cells produced during cell division, and cell division is mostly carried out when people sleep. Reasonable sleep helps the body to control cells from changing.

Eight, eat garlic to prevent cancer: eating garlic regularly can not only block the synthesis of nitrosamines in the body, but also stimulate human macrophages to devour cancer cells.

Nine, hairtail anti-cancer: In recent years, scientists have found that the silvery white oil on hairtail contains an anti-cancer ingredient-guanine sulfide, which can effectively treat cancers such as acute leukemia.

Ten, often eat vegetables to prevent cancer: chlorophyll and sodium salt in vegetables are effective anti-mutagens and have anti-cancer effects.

Eleven, olive oil cancer prevention: biological experiments show that eating olive oil alone can prevent breast cancer. Scientists believe that this may be because olive oil contains less easily oxidized unsaturated fatty acids, but contains antioxidants and other substances including vitamin B, thus playing an anti-cancer role.

Twelve, eat some fat to prevent cancer: eating some fat can make the cholesterol content in the blood not too low, and enhance the anti-cancer ability of the human body.

Thirteen, carotene cancer prevention: people who eat rich beta-carotene in food have a lower chance of developing cancer. If the daily intake of beta-carotene reaches 6 mg, it can protect the body and prevent cancer.

This seems to be similar to what we often say about a healthy lifestyle. What do we need to know about a healthy lifestyle?

First, the diet is healthy: eat more fruits and vegetables, miscellaneous grains, low fat and low salt. As far as diet is concerned, most people in China are mainly cereals and vegetables, which are "green foods". But on the whole, protein is slightly insufficient, so in the "vegetable basket project" of the Shanghai municipal government, measures were taken to change grain into eggs, milk and meat. Generally speaking, you can eat more birds, eggs, milk and so on. However, in economically developed areas, residents eat too much fat. High-fat diet leads to hyperlipidemia, which is the root of arteriosclerosis, can cause cardiovascular and cerebrovascular diseases, and is the main killer of Chinese people's health. High-fat diet will also increase the incidence of colorectal cancer and breast cancer, and fatty liver and gallstones are also related to it. High salt is also a problem in our people's diet. Salt is a necessity in life, but taking too much salt will increase the incidence of hypertension. High salt destroys the barrier function of gastric mucosa and increases the incidence of gastritis and gastric ulcer. High-salt diet makes carcinogens easy to invade, and gastric cancer is also high. Therefore, we should advocate a low-fat and low-salt diet. If you don't eat breakfast for a long time, you are prone to chronic stomach problems. Due to the imbalance of nutrition, your body's resistance drops, and you often feel lack of energy. Eat well for breakfast, eat enough for Chinese food and eat less for dinner. The combination of meat and vegetables, balanced nutrition, if you go out to eat, eat half, and take the rest home for a late supper. Eat more fish, it is best to choose smaller fish, such as wild or organic salmon, fresh sardines and so on. Often eat foods rich in cellulose, and eat about 25g of foods containing cellulose every day, such as whole wheat food, whole oat food and brown rice. Supplementing nuts and fruits before meals, such as citrus, contains flavonoids and has anti-cancer effect, so that you can get enough vitamins, especially vitamin D supplement, to ensure energy.

2. Seek medical attention in time when sick: The survey shows that nearly half of the people buy medicine to solve the problem when they are sick, and 1/3 of them simply ignore any superficial "minor illness". The "minor illness" was delayed again and again, and the best treatment opportunity was missed. Some diseases have been covered up by the relieving effect of drugs on the surface, and accumulated into serious diseases, and it is too late to regret. The correct way is not to delay the illness, make timely diagnosis and treatment, prescribe the right medicine, and nip the disease in the bud.

Third, take the initiative to have regular physical examination: A healthy lifestyle also includes an understanding of health and diseases. If some units organize physical examinations for employees, some people just don't want to attend, thinking that they are not sick, so why bother to check the problem. In fact, diseases exist objectively, and it is better to diagnose and treat many diseases early. Take an active part in the physical examination when you have the opportunity. Another example is that some people suffer from chronic diseases, such as hypertension and diabetes, which are ignored because there are no special symptoms in a short time. After a long time, all kinds of complications appear, or stroke (stroke), hemiplegia, or neuritis, gangrene of the foot, and it is too late to regret. Others have heard that some diseases need lifelong treatment, and they think that they can't be cured anyway, so they don't care. Even patients with hypertension have a headache, and they only use cold water to wash them, hoping to relieve them. In fact, hypertension or diabetes, as long as serious treatment, blood pressure can be completely reduced to normal levels, blood sugar can also be maintained normal, and you can live like a normal person. For example, a nearsighted person wears glasses and can see everything, just like a normal person. You can't let yourself see nothing just because you hear that you will wear glasses all your life. Therefore, it is necessary to have a regular and comprehensive physical examination every year. Individuals should take the initiative to have a physical examination at least once a year, regardless of whether they organize the examination in a unified way.

Fourth, be sure to have a good breakfast: skipping breakfast or stuffing a few mouthfuls at will has become a common phenomenon. In fact, skipping breakfast will seriously hurt the stomach, make people unable to study and work energetically, and make people "look old" easily. After a long-term follow-up survey of 7,000 people, researchers at the University of Herun found that 40% of them used to skip breakfast, and their life expectancy was 2.5 years shorter than that of the remaining 60%. Another university in Germany found that one of the similarities of their longevity is to eat a hearty breakfast every day in the study of the elderly aged 80-90. Be sure to eat hot food for breakfast.

5. No matter how busy you are, you should take time to communicate with your family: life is limited, work is unlimited, desire is unlimited, family is more precious, and frequent communication with your family will make you feel relieved and happy. You can also subscribe to a magazine about love. When you feel depressed and sad, open it. You will feel that the world around you has become better and the pressure has been reduced a lot.

6. Avoid being in an air-conditioned environment for a long time: We live in an air-conditioned room almost all the year round and become "greenhouse people". Leading to a decline in the body's ability to regulate and resist diseases. Avoid staying in an air-conditioned environment for a long time, and it is best to turn off the air conditioner after 1-3 hours. It is best to set the air conditioning temperature at 25-27℃, and the temperature difference between indoor and outdoor exceeds 7℃, which will increase the burden on the body's temperature regulation center and cause neuromodulation disorder. Unless extreme weather, turn on the air conditioner carefully, natural ventilation and sunshine will greatly improve the physical and mental condition, and happiness and happiness are in sunny places!

Seven, not sedentary, regular exercise: many people will never stand up easily unless they go to the toilet. Sedentary is not conducive to blood circulation, causing metabolic and cardiovascular diseases, and long-term fixed sitting posture is also an important factor in the pathogenesis of cervical and lumbar vertebrae. Standing up and exercising often is a compulsory course for white-collar workers.

Eight, to ensure adequate sleep time: if you often take a nap during the day, fall asleep or doze off while reading a book or watching a movie, it means that you lack high-quality sleep, improve efficiency, and develop the habit of going to bed regularly. It is best to take a nap from 1 in the afternoon, when people feel less and fall asleep more easily. It is better to sleep at night 10 to 1 1, because people's deep sleep time is from 24: 00 to 3: 00 the next morning, and people enter a deep sleep state after sleeping for an hour and a half. You can choose breathing exercises such as meditation and yoga to help you fall asleep and stay healthy.

Nine. Discontinuously facing the computer for too long: excessive use and dependence on the computer, in addition to radiation, is also prone to eye diseases, cervical spondylosis, hemorrhoids, RSI (repetitive strain), mental illness is also very common in white-collar workers. Be sure to get up regularly after 1-2 hours, then sit in front of the computer and stretch your arms and kick, breathe fresh air and speed up blood circulation.

Ten, take the initiative to adhere to physical exercise every day; Moderate and continuous lack of exercise is also a major shortcoming in modern life. There is an elevator upstairs, a car when going out, hands-free laundry and microwave oven to make a living, which not only lacks exercise, but also simplifies general labor. People's physique is preserved, and it will degenerate after a long time, so muscle weakness, osteoporosis, fat accumulation, obesity, lumbar spondylosis and cervical spondylosis will follow. Therefore, sports should be promoted. Take a brisk outdoor walk for an hour every day. The standard is to walk 3 kilometers gradually in 28 minutes, which is equivalent to normal stride 134 steps/minute. It consumes the most calories and is most conducive to slimming. It is best to take a walk 45-60 minutes after a meal, and it is better to take a walk two hours after a meal. You can also twist your body with beautiful music in the living room. When you exercise according to the rhythm of music, your heartbeat and breathing are perfectly unified in the elegant rhythm. This kind of "dancing" needs at least twice a week, and the effect after long-term persistence will be so good that you can't believe it!

XI。 Correct outlook on life and world: The modern concept of health refers to physical and mental health and good adaptation to the environment. In the past, mental health problems were ignored, and the basis of mental health should be to establish a correct outlook on life and world. For example, interpersonal relationships, from a general point of view, I am the foundation of everyone, and we can't just ask everyone to do it for me. Specifically, everything should be divided into two parts. People should pay more attention to the advantages of others, be lenient with others and be strict with themselves. If everyone can do this, interpersonal relationships will naturally be harmonious. A healthy person with hard work and enterprising spirit, confidence and determination to overcome all difficulties, can naturally adapt to society and environment well. Modern people should have scientific and civilized ideas about their health. Establishing a healthy and civilized lifestyle is exactly the quality that modern people should have.

Twelve, quit smoking and limit alcohol: smoking is a bad hobby. Compared with non-smokers, smokers are 10 times more likely to develop lung cancer, 8 times more likely to develop laryngeal cancer, 6 times more likely to develop esophageal cancer and 4 times more likely to develop bladder cancer. Smokers are prone to coronary artery spasm and increase the incidence of cardiovascular diseases. Smoke destroys bronchial mucosa epithelium, and smokers suffer from chronic bronchitis. Chronic bronchitis can lead to emphysema and pulmonary heart disease, and it is also an important killer of Chinese people's health. Alcohol damages the liver, which is occasionally acceptable. Alcoholism can lead to alcoholic cirrhosis, and alcohol is also a cancer-promoting substance. The incidence of liver cancer increases in those who continue to drink alcohol after hepatitis. So no smoking, no drinking.

After comparison, we can easily find that the daily anti-cancer method is what we often call a healthy lifestyle. So, what role does a healthy lifestyle play in preventing cancer?

The first is the role of a healthy diet in preventing cancer. There are many foods in modern life that affect our health. We often go to KFC and McDonald's. However, according to the formula provided by Professor Su, deputy director of the Department of Nutrition, School of Public Health, Sun Yat-sen University, and vice chairman of the China Nutrition Society, it is suggested that the daily fat intake should be 60 to 70 grams, and the proportion of three meals a day should be about 20 to 23 grams respectively. If calculated in this way, the fat in the spicy chicken leg burger exceeds the recommended value of 40%. "If you add ice cream cones or apple pie, obviously you will have more fat intake." In the children's happy paradise package with spicy chicken wings, the one with the highest combined fat content reaches 40 grams, and there are no fewer than seven or eight kinds over 30 grams. If you choose spicy chicken leg hamburgers, French fries (medium) and drinks for a meal, the calories will reach 1000 calories, just a meal. If you eat more calories and exercise less, you will store fat. French fries are processed from starch at high temperature and high oil, which will produce a chemical called acrylamide. Animal experiments have proved that this chemical is carcinogenic. This shows that this is not a healthy diet. A healthy diet includes fruits and vegetables, miscellaneous grains and low fat and salt. They contain isothiocyanates, flavonoids, lycopene and cryptoxanthin, also known as zeaxanthin and isoflavones. What role do they play in cancer prevention?

Isothiocyanate. This chemical exists in cruciferous plants, such as broccoli, cauliflower and Brussels sprouts. It can help us resist carcinogens of cigarettes, inhibit tumor growth and inhibit some steroid hormones that promote growth.

Flavonoids Mainly from apples, grapefruit, onions, red wine and tea. In a study on flavonoids, it was found that people who eat apples have a lower incidence of cancer than people who don't eat fruit often. Another study found that people who often eat onions, apples and grapefruit have a half of the incidence of lung cancer compared with those who rarely touch these foods. In addition, flavonoids are also found in foods such as soybeans, strawberries, broccoli, carrots, oranges, eggplant, peppers, pumpkins and tomatoes. Flavonoids in dark chocolate can prevent lung cancer (but not other tumors).

Lycopene. Lycopene is a chemical substance rich in tomatoes, which can also prevent lung cancer. Moreover, the function of this beneficial substance will be enhanced in the cooking process of tomatoes.

Cryptochrome, also known as zeaxanthin. Cryptochrome is an orange pigment. Some studies report that eating foods rich in cryptoxanthin can reduce the risk of lung cancer. Foods rich in cryptoxanthin include pumpkin, corn, papaya, orange, sweet pepper, orange and peach. However, further research on this substance is needed.

Isoflavone. Isoflavones exist in soybeans and flaxseed, and some of their biological functions are similar to estrogen. There is evidence that 5,7,45-trihydroxyisoflavone in soybean can prevent lung cancer.

The role of timely medical treatment and active regular physical examination in cancer prevention: regular cancer examination (colon cancer, breast cancer, prostate cancer, uterine cancer and skin cancer, etc. ), and ask the doctor about the age and time interval requirements of physical examination. It can be found that early cancer can increase the possibility of cure and reduce the chance of death.

The role of correct outlook on life and world outlook in cancer prevention: the occurrence of cancer is closely related to psychological factors. Some experts even think that personality determines the probability of cancer. Optimistic and cheerful personality and good psychological quality can not only prevent cancer, but also help cancer treatment. Those negative emotions such as sadness and despair may damage people's immune system and induce cancer.

The role of daily physical exercise in cancer prevention: the exercise mentioned in the book is not the exercise in the competition, but the long-term, sustained and effective aerobic exercise. This sports bag contains relatively stable sports science such as jogging, brisk walking, swimming and cycling. Moderate exercise is aerobic exercise for at least half an hour three times a week, or at least 20 minutes four times a week. Perseverance is very important. Because exercise redistributes blood, for example, the amplitude of temporal artery decreases, the amplitude of radial artery increases, the intentional part of blood volume increases, and the unintentional part of blood volume decreases (indicating that the brain can mobilize its own blood flow redistribution), thus improving capillary permeability, strengthening capillary patency, increasing capillary loops and improving flow pattern; At the same time, changing the blood composition and the function of blood cells can activate hematopoietic function. For example, after exercise, eosinophils, hemoglobin, red blood cells and platelets can all increase in different degrees, and the phagocytic function and phagocytic index of white blood cells tend to increase. Anti-cancer body-building method consciously adjusts the distribution of blood in the body through intentional defense, thereby increasing the blood flow per unit time in cancer tumor area (intentional defense of this part), enhancing capillary permeability and increasing the vitality of anti-cancer factors, thus achieving the purpose of anti-cancer treatment.

From this perspective, cancer is not terrible. We should pay attention to our daily life style and be a healthy person.
