Did you know that there are 3 conditions that increase the risk of lung cancer?

Frequent exposure to secondhand smoke, which is harmless to smoking is similar to smoking. The chances of developing lung cancer from cigar smoking are twice as high as those of non-smokers. Often near the hood, cooking is also prone to cancer.

For example, I often smoke and drink alcohol, or I often stay up late, I often overeat, I don't have a healthy diet, or I am often exposed to second-hand smoke, or I often smoke e-cigarettes, my life is very irregular, or my living environment is very poor, etc.

I often stay up late, smoke and drink a lot, sometimes go to places with a lot of smoke and dust, and often eat pickled food.

The study found that men who smoked more than 2 boxes a day had a double risk of lung cancer. The more you smoke and the longer you smoke, the greater the risk. More than 90% of lung cancers are caused by active smoking or passive exposure to secondhand smoke.

Evidence suggests that people who live with smokers and thus consume secondhand smoke have a 20-30% increased risk of lung cancer. By stopping smoking before lung cancer develops, the lung tissue can slowly return to normal.

Stopping smoking at any age reduces the risk of lung cancer, heart disease and stroke. Even after a diagnosis of lung cancer, stopping smoking can help improve the patient's respiratory and general health and reduce the likelihood of developing a second lung cancer, while increasing the likelihood of success at the moment.

In addition to smoking, there are other risk factors that can lead to lung cancer, including:

Environmental factors: Radon is an odorless radioactive gas produced by the natural decay of uranium, and areas with relatively high radon levels in the working or living environment (such as uranium mining areas) can increase the risk of lung cancer. People who are exposed to dust or asbestos at work also have an increased risk of lung cancer.

History of respiratory disease: a history of previous lung disease (asthma, chronic obstructive pulmonary disease, pneumonia, and tuberculosis) is a risk factor for lung cancer, with tuberculosis being the most closely related.

Air pollution: The amount of pollutants in the air is directly proportional to the probability of developing lung cancer. For every 10 micrograms of pollutants in 1 cubic metre of air, the risk of lung cancer increases by 8%. The increasing incidence of lung cancer in women is currently believed to be closely related to kitchen fumes.

Psychological factors: poor psychological adaptability, long-term mental depression, and significant type A personality (referring to fast movements, impatience, strong aggressiveness, and irritability) will increase the risk of lung cancer.

Nutritional imbalance in diet: Intake of more vegetables and moderate amounts of fresh fruits has a protective effect on lung cancer; The greater the intake, the more obvious the protective effect. Vegetables and fruits mainly contain vitamin A, vitamin C, vitamin E and trace elements such as selenium, germanium, platinum, magnesium and zinc, which have the functions of inhibiting the expansion of DNA of cancer cells and blocking the synthesis of carcinogens.

With such a high incidence of lung cancer, what are the currently recognized risk factors for lung cancer?

1. Smoking and passive smoking:

Smoking is currently recognized as the most important risk factor for lung cancer, and more than 60 carcinogens are formed during the ignition of cigarettes.

Nitrosamines, polycyclic aromatic hydrocarbons, benzopyrene, etc. in tobacco are highly carcinogenic substances to the respiratory system.

Among them, the younger the age at which smoking begins, the longer the number of years you smoke, and the greater the amount of cigarettes, the greater the risk of lung cancer.

2. Indoor pollution:

Indoor pollution mainly includes pollution caused by indoor fuels and cooking fumes.

Incomplete combustion of indoor coal fuel and cooking fumes can produce benzopyrene, formaldehyde, polycyclic aromatic hydrocarbons and other carcinogens.

3. Indoor radon exposure:

Radon is radioactive, and when inhaled, the radioactive particles that decay in radon can cause radiation damage to the human respiratory system and cause lung cancer. High radon levels around uranium-bearing mining areas.

Building materials are the most important indoor radon**, such as granite, brick sand, cement and gypsum, especially natural stone containing radioactive elements.

4. Outdoor air pollution:

Carcinogens in outdoor air pollutants mainly include benzopyrene, benzene, some metals, particulate matter, ozone, etc.

5. Occupational factors:

A variety of specific occupational exposures can increase the risk of lung cancer, including asbestos, quartz dust, nickel, arsenic, chromium, dichloroethyl ether, mineral oil, dichlorome ether, etc.

6. Family history and genetic predisposition to lung cancer

It is often found that if someone in the family has lung cancer, other members of the family are at increased risk of developing lung cancer.

If there is one lung cancer patient in the family, the lung cancer risk of the other members is twice that of the non-lung cancer patient, and the adjusted risk of more than two lung cancer patients is doubled.

In summary, the incidence of lung cancer ranks first in cancer, and smoking cessation, indoor pollution reduction, outdoor pollution protection, occupational protection, and attention to family history of lung cancer are effective lung cancer prevention measures.

At present, the cause of lung cancer is not clear, after clinical research and epidemiological investigation, the cause of lung cancer may be related to the following points: 1. The occurrence of lung cancer is absolutely related to long-term high-dose smoking, and the prevalence of lung cancer in smokers is significantly higher than that in non-smokers; 2. The occurrence of lung cancer is also related to air pollution, which is a common type of lung cancer; 3. The occurrence of lung cancer is also related to the patient's low immune function, and frequent colds cause lung infections and eventually tumor lesions.

In general, people who like to smoke are more likely to develop lung cancer, especially those who have smoked for 20 years and those who smoke more than 20 cigarettes a day. According to clinical surveys and studies in recent years, smoking is closely related to lung cancer, as well as cancers of the upper gastrointestinal tract, pancreas, renal pelvis and bladder.

1. Smoking: Smoking is one of the most common risk factors for lung cancer, and studies have found that smoking for a long time and a large amount of cigarettes is a greater risk of lung cancer.

3. History of respiratory diseases: Studies have found that people with a history of respiratory diseases have a higher risk of developing lung cancer than normal people, so people with a history of respiratory diseases should do a good job in the prevention of lung cancer.

4. Low body mass index: However, when the body mass index of the human body is low, generally less than 20, the risk of lung cancer will also increase.

5. Psychological factors: Psychological factors are also one of the common risk factors for lung cancer. Long-term depression, sexual urgency, and poor psychological adaptability often increase the risk of lung cancer.

6. Kitchen fumes: Expert studies have found that there is a great relationship between kitchen fumes and lung cancer in women.

7. Air pollution: Living in polluted air for a long time often has a high probability of developing lung cancer.

There are many predisposing factors for lung cancer, which are affected by both external and internal factors. Among them, the risk of lung cancer in high-risk groups is much higher than that of the general population, and the high-risk groups for lung cancer are as follows:

1. Generally speaking, middle-aged and elderly people over 55 years old belong to the high-incidence group of lung cancer, and the incidence of lung cancer gradually increases, reaching the peak at the age of 75-80. Clause.

Second, long-term smokers cigarettes contain harmful substances to the human body, especially tar and nicotine, which are strong carcinogens, and the toxic substances in the smoke will gradually destroy some villi, so that the secretion of mucus increases, so that chronic diseases occur in the lungs, and they are prone to bronchitis, which in turn leads to the occurrence of cancer, therefore, the probability of lung cancer in people who smoke regularly is many times higher than that of others. Clause.

3. Long-term exposure to carcinogensPeople who are exposed to soot or oil smoke for a long time, such as gas, asphalt, coking workers, and cooks and housewives who are exposed to kitchen fumes for a long time, have a higher incidence of lung cancer than the general population. Clause.

4. People living in areas with serious environmental pollution for a long time have a greater chance of developing lung cancer than ordinary people. Studies have found that 80% of malignant tumors are induced by environmental factors, and there are a large number of carcinogens in the environment in which humans live, which is the main reason for the increasing incidence of cancer year by year. In addition, there are some people who have been exposed to radiation for a long time, people who have received excessive radiation exposure inside and outside the body, such as individuals working in metal mining areas, who have been exposed to inorganic arsenic, asbestos, chromium, nickel, etc. for a long time, and lack of protection, and the risk of lung cancer is higher than that of the general population.

In addition to this, personality factors are also very important. View the original post

Smoking has a long history and is most likely to get lung cancer due to factors such as smoking, air pollution, chemicals, physiological factors, and so on.

The incidence and mortality rate of lung cancer in China is very high, so we have been analyzing why the incidence of lung cancer in China is so high, and we also use smoking plus six modernizations to summarize and describe the incidence of lung cancer in China, smoking is a major cause of lung cancer, there are thousands of chemicals in tobacco, hundreds of harmful substances, 69 clear carcinogens, and our second-hand smoke and third-hand smoke, so smoking is the main culprit of lung cancer.

<> what is one of the most disgusting things in the world? I said it's a disease, right? Because we are very painful when we are sick, and some people even suffer from those diseases that are difficult to **, or directly cannot be **, which is what makes people feel hopeless!

Because if the sick constitution cannot be cured, then it means that the person is slowly moving towards the end of his life......And there is nothing to be done! Cancer is even more frightening. So which groups of people are more likely to develop lung cancer in their daily lives?

I think most people have a bottom in their hearts, that is, people who like to smoke very much on weekdays and passive smokers, here passive smokers refer to those who are close to smokers, inhaled second-hand smoke, it is said that the second-hand smoke that people inhale is the smoke exhaled by smokers, and the harm to the body is greater than that of the smoker himself. So we must stay away from those who smoke on weekdays, while they are smoking.

And as a smoker, we should not smoke in public places or in some narrow and impermeable places in the elevator, so as not to bring unnecessary harm to others! It has been scientifically proven that people who smoke for a long time are 10 to 20 times more likely to develop lung cancer than people who do not smoke for a long time, so if there is not much need to quit smoking, try to quit smoking if we can, and those who do not smoke should not touch the tobacco thing, after all, quitting smoking is not an easy thing. With the development of time, there are more and more women who smoke, but here is a small knowledge point, as a woman, it is necessary to understand, that is, women who smoke are twice as likely to develop lung cancer as men.

Although sometimes we may encounter something that makes us feel uncomfortable, we always think of solutions, because there are always more solutions than difficulties, and we are not the only ones who can solve problems through smoking. So if we don't touch the cigarette, don't touch this thing!

There are also people with a family history of tumors, and many tumors have obvious familial aggregation characteristics, so people who have a family history of malignant lung cancer should pay attention! The third is people with tuberculosis, especially those who developed tuberculosis in their early years. If the lesion increases gradually, then we should always pay attention to the possibility of deterioration.

There are also some people who have low immunity on weekdays, and they are also more likely to suffer from lung cancer, because the disease will take advantage of their weakness at this time. Therefore, we must maintain a more happy mood on weekdays, and ensure that there is a certain amount of exercise every day, it is said that life comes from exercise, and we must exercise more to accelerate the metabolism of our body, so that every cell in our body is full of health and vitality! The above are some people who may be more prone to lung cancer than ordinary people, so in addition to the above group of people, which other people do you think may be more prone to lung cancer than ordinary people?

People who like to smoke, have frequent contact with dust, and are born with bad lungs have a higher risk of developing lung cancer!

The 21st century is an era of highly developed science and technology, science and technology have added a lot of convenience to people's lives, and at the same time, many diseases are getting younger and younger, some diseases that used to be only middle-aged and elderly people will now suffer from them at a young age, such as lung cancer, which is the case with lung cancer, and there are usually the following types of people who are prone to lung cancer in life.

After a meal, a cigarette is happy like a fairy, this sentence describes the life of many men, some people will always habitually take out a cigarette from their pocket and light it after dinner, as if smoking helps to eliminate food, but it is such a small action that increases the risk of cancer to themselves!

Cigarettes contain many ingredients that have negative effects on the body, such as nicotine, toluene, arsenic, and so on. Nicotine is an insecticide that is very toxic to the liver and lungs, toluene is a common industrial solvent, which is not easily soluble in the blood and can easily accumulate in the lungs, while arsenic is another name for arsenic, which is needless to say that everyone knows how harmful it is! Cigarette lovers have a high chance of becoming cancerous because their lungs are poisoned by harmful substances all year round than those of non-smokers, and the risk of cancer in passive smokers is also not small!

In addition to cigarettes that can easily cause lung cancer, the same is true for dust in the air, and people who are often exposed to dust in work and life are also at great risk of lung cancer.

Coal diggers, miners, carpenters and other workers should be effectively protected at work to protect their health rights!

The lungs are one of the five organs of the human body and play an extremely important role in the human body, but some people are born with fragile lungs, and the probability of lung cancer in such people is also greater than that of ordinary people. In addition, people who often eat fried food or are exposed to oil smoke will also have a greater risk of lung cancer!
