This is a difficult topic to answer accurately, and cancer is sometimes indefensible.

Early stage of many tumors have no symptoms, such as thyroid cancer, kidney cancer, esophageal cancer, colorectal cancer, pancreatic cancer, etc. With the increase of tumors, there will be pressure and infiltration of surrounding tissues, and then corresponding clinical symptoms will appear. Therefore, to prevent tumors, it is necessary to pay attention to medical checkups and have regular medical checkups. Women should check breast, thyroid, uterus, etc., and smokers should check chest X-ray, etc.

From the digestive system tumor alone, some habits need to pay attention to: 1. Eat and sleep on time. Young people especially do not get into the habit of not eating breakfast 2. Avoid eating overnight food, avoid pickled food, to know how to take (the loss of bad habits, to be healthy) 3. Hepatitis people must avoid alcohol, need to regularly monitor the hepatitis virus and liver function 4. Family with digestive system tumors suggest focusing on the digestive system.

People in general are afraid of cancer. It is true that cancer, if not detected early, is mostly incurable under the current level of medical care. And early detection of cancer is not so easy, the key is that it requires frequent checkups and expenses, so many people will not invest their time and funds in early screening of cancer either. Therefore, cancer prevention becomes very important and has become the most acceptable thing for many people.

So, are these so-called "good habits" useful in the prevention of cancer? I think they are useful.

When it comes to cancer prevention, almost everyone thinks of "quitting smoking". Some people say, "My grandma smoked for 90 years and lived to be more than 100 years old, and the doctors who advised her to quit have died several times. It is true that smokers are not 100% likely to get cancer, and non-smokers are not immune to cancer. It's like tossing a coin twice, the chance of it being positive at the same time is only one in four. But we can easily see the overall relationship between smoking and lung cancer. Looking at the chart below, the rate of smoking in the U.S. population has declined by nearly 30 percentage points since the 1970s.

In contrast, the incidence of lung cancer in the United States from the 1990s to the present has been on a downward trend, especially in men, which has declined by more than 40 percent. Lung cancer in women has risen slightly in recent years because the change in smoking prevalence in women has not been significant. In addition, countries with high smoking rates, such as Russia and Turkey, have higher rates of lung cancer.

The second example is obesity. Some people say, scientific research just say that obese people inside the cancer will be more, not that obesity can cause cancer. It is true that the mechanism of obesity cancer is still being studied, but "obesity", itself is a comprehensive factor, for example, most obese people do not like sports, most obese people do not like to eat vegetables and fruits, most obese people like overeating, most obese people like to eat barbecue fried meat, most obese people sugar The intake of obese people, and so on, these unhealthy factors, many of which are carcinogenic, such as long-term eating barbecue meat and over-processed food, such as not eating vegetables and fruits that have a protective effect on health, and so on. So the high incidence of cancer in obese people is the result, the reason is a combination of various factors.

So, it is possible to reduce the risk of developing cancer with healthy habits. Please note that I am talking about reducing the risk of developing cancer, not preventing it. In addition to the drinking environment and living habits related to the occurrence of cancer, another factor is genetic inheritance, perhaps this is a more critical factor, which is why some people smoke, drink, eat fat meat and do not exercise, and still live a long life; there are people who have good living habits, live in a good environment, but the result is still cancer. If there is a genetic defect, then maybe that plays a bigger role than lifestyle habits. But if you can lower it a little, you can lower it a little.

One more word on simple cancer prevention habits:

1. Don't smoke, don't drink or drink less;

2, regular habits of life and work, do not stay up late, regular meals, less snacks

3, eat less processed red meat (bacon bacon ham and sausage, etc.), eat more vegetables and fruits, eat more roughage less refined grain

4、Attention to sports, happy mood

[Dr. Liu Yongyi No. WD192]

There is no simple and completely effective way to prevent cancer, and it seems impossible to think that one can take a needle or drink a pill and be free of cancer! We are still far from knowing its pathogenic mechanism and nature, that is to say, we do not have a clear understanding of it, so how can we prevent it?

The current approach is to eliminate, avoid and reduce the high-risk factors for cancer, improve one's physical fitness, and maintain a good and healthy state of mind, among other measures, in order to reduce and minimize the occurrence of cancer. These are etiologic prevention, primary prevention, a longer process, and basically a lifetime of being on guard against cancer.

Cancer is its own tissue cell degeneration of crippled criminals, groups. Unlike hepatitis, tuberculosis, which get sick due to exogenous microorganisms infecting the body, a line of defense is built up inside the body in advance after the body is vaccinated to prevent it! Cancer is a problem inside, there is no way to get an effective line of defense to keep cancer out, right?

More than 90% of cervical cancer is caused by human papillomavirus (HPV) infection, which has a relatively effective way, the vaccine! The vaccine has quadrivalent vaccine, nine-valent vaccine, meaning that there are many subtypes of the HPV virus, to prevent a subtype is a price, the most common infections are HPV16, HPV18. the vaccine has been in foreign countries to begin to vaccinate for more than 20 years, has been given to us to test, last year, also began to vaccinate in the country, roughly 3,000 yuan, the population under 45 years of age to go to the local vaccination station to consult the good man to also performance The good man is also going to show up. Cervical cancer is also the first cancer that human beings are most likely to defeat.

There is a clear causal relationship between liver cancer and hepatitis, hepatitis B. Have you gotten the hepatitis B vaccine? Have you checked your body for antibodies? Without hepatitis B, liver cancer is more than half less likely! If you are infected with Hepatitis B, then you need antiviral treatment, to minimize the damage the virus does to the liver. What about alcohol? Detoxification in the liver, so that the liver load full, damage ah! So don't drink alcohol if you have hepatitis.

Lung cancer, the number one cancer, and I'm sure we all know about this high risk factor, smoke! Smokers, second-hand smoke, air pollution, kitchen smoke, renovation of new house odor and so on.

Cancer of the digestive tract, the food connection! Nitrites, which shake out in the stomach into nitrosamines, which are carcinogens! Esophageal, stomach, colorectal cancers are all linked. Gastric cancer has 90% of people with Helicobacter pylori infection, fecal-oral transmission, if there is a family history of gastric cancer, atrophic gastritis, gastric ulcers or eradicate Helicobacter pylori, HP!

Breast cancer is linked to estrogen. Women can't have no estrogen, can they? To avoid the causes of abnormally high estrogen, including late childbearing, infertility, not breastfeeding children, and obesity, with special emphasis on exogenous estrogen, beauty products, why beauty, estrogen can make the skin smooth and tender, too much is not good, right. Especially if you have a family history of breast cancer, you should try not to use beauty products, and is the quality of that stuff reliable? Breast cancer is also closely related to heredity, Hollywood movie star Jolie is not preventive mastectomy double breasts.

There are so many other factors that contribute to the detection of cancer, as well as pharmacological interventions for high-risk groups, all of which are etiologic prevention, and there is also a secondary prevention system of early detection and early treatment. Understand your own physical condition, know which areas to focus on, and learn more about cancer prevention and fight against cancer!

I'm @Dr. Liu Yongyi , thank you for reading! If you have any questions, please leave them in the comments section.

Cancer prevention is closely related to our diet, lifestyle habits, and working and living conditions. The World Cancer Research Fund and the American Institute for Cancer Research have launched the most comprehensive and authoritative report to date on lifestyle and cancer prevention, including diet, nutrition, weight and exercise. The report offers ten recommendations on cancer prevention.

1. Maintaining a healthy body weight, within the normal body mass range (BMI of 19-24 kg/m2) at the lowest possible level, regular physical activity and limiting the intake of energy-rich diets and beverages are key strategies for maintaining a healthy body mass.

2. Exercise, recommended: at least 150min of moderate-intensity physical activity or 75min of high-intensity physical activity per week. Moderate-intensity activities include: walking, cycling, swimming; high-intensity activities include: running, fast swimming, aerobics.

3. Eat a diet rich in whole grains, vegetables, fruits and legumes.

4. Limit intake of "fast food" and other processed foods high in fat, starch or sugar.

5. Limit consumption of red meat (e.g., beef, pork and lamb) and processed meat products, and if red meat is consumed, do not exceed three servings per week, equivalent to approximately 350-500 g cooked weight.

6. Limit the intake of sugary beverages, suggesting that it is best to drink water, tea or unsweetened coffee, and not to drink large quantities of fruit juices.

7. To prevent cancer, limit alcohol consumption, preferably by avoiding it. If alcohol is consumed, it should be no more than two servings per day for men and one serving per day for women, with one serving containing 10-15 g of alcohol.

8. Supplements are not indicated for cancer prevention, and most healthy people receive adequate nutrition through a balanced diet.

9. Adhere to breastfeeding, exclusively breastfeeding for six months and continuing to breastfeed until the age of two or more after complementary feeding.

10. Cancer patients should follow cancer prevention recommendations after treatment.

To summarize, to avoid the occurrence of cancer, it is necessary to change the bad habits and ensure the regularity and rationality of good living habits. In addition to the above suggestions, it is also necessary to maintain a good state of mind, conduct regular health checkups, and do tumor screening every six months for those with a family history of tumors.

The authoritative interpretation of Pharmaceutical Affairs, unauthorized reproduction, plagiarism will be punished.

(1) Maintain a positive mood; maintaining a good mood can improve the state of immune system function, so as to achieve the purpose of anti-cancer.

2) Adopt good living habits; irregular life tends to cause fatigue, decreased immunity and illness.

(3) pay attention to dietary nutrition and safety; the so-called "disease enters by the mouth", so the diet should pay attention to reduce the pesticide residues of fruits and vegetables, fruits and melons can be washed and soaked in warm water, and then scrubbed with a brush; leafy vegetables can be rinsed one by one the internal leaves. Eat less fried food, because the oil temperature is too high will produce a lot of benzopyrene, acrylamide and other carcinogens. Eat more fresh fruits and vegetables, fresh fruits and vegetables contain antioxidants, carotenoids, vitamin C and so on can play an anti-cancer role.

(4) Pay attention to abnormal changes in your body; pay more attention to changes in your body and seek early medical attention if you feel unwell.

(5) Regular medical checkups; regular checkups allow for early detection and treatment, eliminating diseases at an early stage.

Hello, thank you for your question! Most of the advice given by the experts is based on years of clinical experience, and it is useful in the matter of cancer prevention, and there is still more to pay attention to in normal life.

Cancer is very scary, and it is a tumor disease that endangers physical and mental health. Cancer prevention has become the consensus of medical doctors from all over the world, and the unintentional habits of daily life are closely related to the occurrence of cancer, so what we can do is to do a good job of prevention to reduce the incidence of cancer.

[Cancer Prevention Tips]

1. Regular annual checkups, comprehensive body checkups, early detection and early treatment, and awareness of cancer detection will greatly reduce the chances of getting cancer;

2. Reasonable diet, bad dietary habits greatly increase the chance of cancer, eat more fiber-rich foods, reduce fat intake, and enhance good nutrition;

3, do more exercise, maintain a normal body weight, can not be too obese, and can not be thin for the sake of beauty, exercise can strengthen the immune system, enhance cardiorespiratory function, physical function;

4. Know your family history. Heredity is the biggest trigger for fatal cancers, and if there have been instances of cancer in the immediate family, it is more important to be aware of it and do regular checkups when you are young;

5, forbidding to stop drinking, do not smoke, long-term smoking and alcoholism of people suffering from cancer than the proportion of people who do not smoke and drink 80 times higher;

6, have a good mind, the mind is very important, sometimes sick more than their own scare themselves, love to laugh at people's luck are not too bad.

Thank you for your question and I hope it helps!

What should I pay attention to prevent cancer? This question opens Baidu will come out a whole lot of answers. Are there any really reliable ones? How many? Who knows? Even the gods can't tell! A specialist at the hospital will tell you this and that. Is he right? Will he get cancer next minute? He doesn't know! Why? Because there is no authoritative conclusion as to the cause of cancer. To talk about prevention and what to pay attention to in an environment where we don't even know why we get cancer is not going to be very accurate and objective. But does this not mean that cancer is not prevented? It doesn't. Some good habits are still very useful, not only to prevent cancer can also have a lot of benefits. For example: Diet: Don't eat too much sugar, salt and monosodium glutamate (MSG). Eat more vegetables and fruits, as well as coarse fiber foods, grains and so on. Don't eat too much animal fat, especially don't eat more lavender, pickled food. Two: to control weight not too fat. More exercise, exercise can help discharge body waste. Three: quit smoking, control alcohol, give up bad habits. Four: do not stay up late, especially women, the American Association for Cancer Research survey found that less than 7 hours of sleep per night women, the chances of breast cancer to increase by 47%. Five: to have a healthy and optimistic state of mind, long-term depression, the incidence of cancer will greatly increase the chances of malignant tumors, especially in the gastrointestinal tract. Attention to the above aspects of cancer prevention will be of some help!

Talking about cancer is like being afraid of a tiger.

It's a matter of money and life and death.

Dietary modifications should be made before it's too late.

Good balance of yin and yang control.

Until today, it has been impossible to find definitive evidence to explain the cause and course of cancer. Because of this, cures for cancer are always being researched.

The correct use of good therapeutic food health, can effectively inhibit the body metacancer gene mutation and control the intake of carcinogens, greatly reducing the risk of cancer.

The World Health Organization has published the ten iron rules of diet for cancer prevention:

1. Diversification of food

Diet diversification, comprehensive intake of nutrients, plant-based food, to account for more than 2/3 of each meal, plant-based food is rich in vitamins, amino acids, can prevent and fight cancer.

2. Eat more starchy foods

Eat 600-800 grams of various cereals and legumes every day, the finer the processing the better. Starch in food can prevent colon and rectal cancer, and high-fiber food can prevent colon, breast, rectal and pancreatic cancer.

3. Eat more vegetables and fruits

Insist on eating 400 grams - 800 grams of various vegetables and fruits every day, and ensure that you eat more than five kinds of vegetables and fruits every day can reduce the probability of cancer by 20%.

4. Do not eat or eat less burnt food

(1) Barbecue food: contains strong carcinogens benzo(a)pyrene and nitrosamines, and is susceptible to stomach and intestinal cancer.

(2) Smoked food: contains a large number of benzopyrene, often eat easy to esophageal cancer, stomach cancer.

(3) Fried food: Carrying carcinogenic polycyclic aromatic hydrocarbons (PAHs), which can induce cancer and lower the immune system if eaten frequently.

5. Do not eat or eat less pickled foods

Eye nitrates in pickled foods are converted into the carcinogen amine nitrite when they reach the human body.

6. Do not eat moldy food

Grains, in particular, produce the carcinogen aflatoxin when moldy.

7. Do not drink repeatedly boiled water

Water after repeated boiling will produce nitrite, into the human body into carcinogenic amine nitrite.

8. Do not eat overnight vegetables

Green vegetables, even if placed in the refrigerator, more than four hours will produce nitrite, to the body to synthesize amine nitrite carcinogens.

9. Reduce red meat intake

Red meat intake should be less than 90 grams per day, and red meat increases the chances of colon and rectal cancer.

10. Do not promote smoking and drinking

According to statistics, nearly 1/3 of cancers such as lung, esophagus, stomach and bladder cancers are related to smoking.

Regular alcohol consumption increases the risk of oral, throat, esophageal, and liver cancers.

Daily life in a reasonable diet, develop good habits, maintain a good state of mind, regular medical examinations, you can be cancer "outside the thousand miles"!

It has been said that '80% of the causes of cancer in humans come from the environment', which is actually not an exaggeration. This 'environment' refers to the environment in a broader sense, including living habits and dietary habits. Frankly speaking, if people change their bad living or eating habits a little, they can prevent cancer. For example, if a smoker can quit smoking immediately, the probability of his own and his family's cancer will be reduced; if a person who likes to eat preserved food is changed to eat fresh vegetables and fruits, the rich natural vitamin C can help him to inhibit the production of nitrosamines, thus reducing the risk of cancer; vegetables cleaned, fruits peeled and eaten can avoid residual pesticides; pay attention to do not eat moldy rice, pasta, corn, peanuts, sesame seeds, soybeans and so on, then you can avoid cancer, Sesame seeds, soybeans, etc., you eliminate the opportunity to be contaminated by aflatoxin. Another point worthy of our attention is that many cancer patients are young people, which is the root of the problem caused by the richness of modern material life, young people's work and mental stress, unbalanced nutrition, smoking and drinking, night life and other bad habits, resulting in the disorders of the body systems, unknowingly planting the root of the problem. Of course, occasional exposure to all the above 'dangers' is inevitable, and there is no need to worry, because carcinogens may induce cancer only under the stimulation of frequent and long-term exposure. Cancer is not an unpreventable disease as long as we are aware of the relevant knowledge.

Cancer prevention is really about trying to keep the body in a better immune state. After eliminating the role of genetic factors, health self-management through multiple pathways improves immunity and reduces the incidence of cancer.

We are familiar with many cancers, lung cancer, liver cancer, stomach cancer, breast cancer, cervical cancer, direct intestinal cancer, thyroid cancer and so on. In terms of prevention, there are many generic health management responses. Including:

1. Healthy diet

The most common concept refers to the combination of meat and vegetables, balanced nutrition, maintaining good eating habits, regular three meals a day, do not overeat, etc.. What needs extra attention is to eliminate moldy and expired food.Reduce the high oil and fat diet,Leftovers, smoked sauces, barbecued and fried foods.

It is well understood that this is a prerequisite to stay away from gastrointestinal disorders and hence gastrointestinal cancers.

2、Quit smoking and limit alcohol

Tobacco and alcohol are clear risk factors for cancer. Smokers, while not necessarily getting lung cancer, are significantly more likely to get it than non-smokers. And alcohol is definitively damaging to the gastric mucosa and is a contributing factor to many gastric disorders.

3. Good emotional and psychological state

A good spirit has an anti-cancer effect. Many diseases occur in time when the patient's mood is low and immunity is low. This is a point that is much more emphasized in the TCM concept of health and disease prevention.

4. Moderate exercise and weight control

Obesity is a source of disease and a high-risk causative factor for cardiovascular and cerebrovascular diseases and digestive cancers.

It is difficult to summarize the countermeasures and suggestions for cancer prevention in one article, but a common suggestion is to have the habit of regular medical checkups, and people over 40 years of age can be targeted for cancer screening for early detection and diagnosis and treatment!
