Why do so many people who have never smoked develop lung cancer?

There are many people who do not smoke in their lives who will also suffer from pneumonia, a large part of which is caused by inhaling toxic gases or inhaling second-hand smoke, and of course, a small number of people have a chance of developing lung cancer due to genetic reasons.

In life, there are many people who gradually increase the probability of developing lung cancer through smoking, but there are also some people who suffer from lung cancer due to other reasons.

1. Genetic factors.

Genetic factors are also responsible for the probability of lung cancer, and a large number of people in the family may have lung cancer or have the gene to develop lung cancer, and people living in such families generally have the probability of developing lung cancer. If there are people of the older generation in the family who have had lung cancer before and are immediate relatives of themselves, then members of such families must be aware that there may be a risk of lung cancer, so they can choose to have regular check-ups after a certain age. <>

2. Excessive dust inhalation.

If your work is to inhale dust or have a lot of dust. If you inhale too much dust, it will also affect your lungs, so that there is a chance of cancer, because the excessive amount of dust and dust inhaled in your work is easy to lead to lung cancer, and the probability of suffering from lung cancer will be very large. Therefore, you must pay attention to these situations at work, which need to be protected.

3. Inhalation of secondhand smoke.

If someone smokes at home at the same time, although you say that you don't smoke, then you may inhale second-hand smoke, sometimes the probability of cancer from inhaling second-hand smoke is much greater than the probability of inhaling first-hand smoke, after all, second-hand smoke toxicity may be stronger than the toxicity of first-hand smoke, in this case, individuals must avoid, inhaling second-hand smoke can choose to let the smoker go outside to smoke, or stay away from the person who is smoking, in short, do not let yourself inhale second-hand smoke for a long time. <>

Smoking is the most common cause of lung cancer, but it is not the only cause, because in addition to smoking, the incidence of lung cancer is also related to a variety of factors, such as familial genetics and viral infections, as well as radiation and occupational exposure.

Smoking is not the only reason for lung cancer, because many factors can cause human lungs to become cancerous, especially people with a family history of lung cancer, to a certain extent, will be affected by genetic factors, easy to cause lung cancer due to family heredity, lung cancer will occur, which is also a common cause of lung cancer, so those with a family history should have a detailed examination of the lungs every year.

People who never smoke get lung cancer. It may also be passive smoking, even if you don't smoke often in some smoky environments, especially in the same office, and at the same time will continue to smoke or your husband at home continues to smoke, these environments will lead to passive smoking will increase the incidence of lung cancer, in addition to women cooking various dishes in the kitchen for a long time, exposure to oil smoke is also an important cause of lung cancer, if you want to prevent pneumonia, you must stay away from these harmful polluting gases.

Environmental factors are also an important reason for people to suffer from lung cancer, because air pollution in many places is more serious, and haze often occurs, at this time, there will be a large number of harmful substances in the air that people breathe, which will endanger the health of the lungs, and the incidence of lung cancer will be high after a long time. This is also an important reason why people who do not smoke but will develop lung cancer, so in the air pollution and. In hazy weather, be sure to wear a mask to reduce your body's intake of harmful gases.

Viral and bacterial infections, drug injuries, radiation and occupational exposure, etc., are also important factors closely related to the incidence of lung cancer, and are also important reasons for non-smoking to get lung cancer, so we should pay attention to the protection of the lungs in our daily life, do not think that you will not get lung cancer if you do not smoke, if you want to avoid lung cancer, you must stay away from those harmful gases to the lungs, and pay attention to personal protection, do not abuse drugs, prevent bacterial infection, and do a good job of physical examination on time, so as to detect lung cancer as early as possible.

This is due to the influence of the environment, which may be caused by some pre-existing diseases in the lungs, or it may be caused by pneumonia.

Because of secondhand smoke, secondhand smoke is no less harmful than direct smoking.

Why do people who don't smoke still have lung cancer? What are the other causes of lung cancer?

Many people probably think that people with lung cancer smoke cigarettes. The main reason is that smoking is scientifically proven to be an important cause of lung cancer, and I think that's why people have this idea. Isn't it possible for people who don't smoke to develop lung cancer?

The answer is no! Although some people have never smoked a cigarette in their lives, they can also develop lung cancer, so why do people who don't smoke also develop lung cancer? In fact, there are the following reasons why people are at increased risk of developing lung cancer.

The first is that although some people do not smoke all year round, they are immersed in secondhand smoke all year round. Second-hand smoke is the smoke from people who smoke, and when we inhale the smoke they exhale, we suffer more harm than those who smoke.

Second, although smoking is a high-risk factor for lung cancer, it does not mean that lung cancer is rejuvenated, there is only the possibility of smoking, and there is the inhalation of some other oily fumes in daily life. Especially when there is high temperature, it is always harmful to our body! So remember, we must turn on the range hood when we are cooking, and don't let our body suffer in order to save money.

Then there is genetic predisposition, and studies have shown that estrogen in women is linked to lung cancer. So this could also be one of the reasons for the glow of lung cancer.

Therefore, when we see a person who has not smoked all year round suffering from lung cancer, it is not surprising that this type of person is likely to be caused by a series of the above reasons. This also reminds us that we must stay away from others when they smoke, do not let second-hand smoke inhale into our bodies, and at the same time, we can also advise our friends who smoke around us not to smoke in public, which will harm others' bodies.

The cause of lung cancer is still not well understood, and more lung cancer patients who do not smoke can also lead to lung cancer, but some studies have shown that the incidence of lung cancer is higher in smoking patients than in non-smoking patients.

The cause of the disease can be due to the following factors:

1. Internal causes: Internal causes are genetic mutations. Lung cancer caused by non-smoking is mainly caused by internal factors, and the driving factor, that is, lung cancer caused by gene mutations, is a common clinical phenomenon.

Therefore, patients who do not smoke can also lead to lung cancer;

2. External factors: including air pollution, radiation, viral infection or a large number of substances harmful to the lungs in the working environment, are all important factors leading to lung cancer. Long-term inhalation of kitchen fumes is also an important factor that can lead to lung cancer.

Because there are many types of lung cancer nowadays, and it is also possible to cause it due to environmental factors; Exposure to secondhand smoke, kitchen fumes, familial genetics, genetic mutations, radioactive substances or carcinogenic compounds.

Lung cancer is not only caused by smoking, but can also be caused by environmental pollution or even unhealthy psychological conditions. The causes of lung cancer include dust, industrial exhaust fumes, cooking pollution, unhealthy mood, and decoration pollution.

Some people don't smoke but get lung cancer, not because someone's life is bad, but because the ** of lung cancer is not just nicotine, and sometimes the dusty working environment is more harsh and people are prone to lung cancer. This tells us not only not to work in a poor work environment, but also to avoid smoking, so as to minimize the invasion of lung cancer. <>

For many people, smoking is not a good habit, smoking will not only make their lungs black, but also their lungs will become the lungs of the face plug, which is quite a scary thing, which also tells us that smoking can make us enter the stage of old age early. However, more people are curious about how some people can get lung cancer if they don't smoke, mainly because the ** of lung cancer is not just nicotine, lung cancer is sometimes because the function of the lungs cannot be filtered, which leads to lung abnormalities.

In fact, the causes of lung cancer are often very simple and complex, in addition to the well-known nicotine that makes the lungs become plugged lungs, some other reasons can also cause problems in your lungs. In terms of dusty working environments, although we often need to wear protective clothing, this cannot completely filter out the dust from the outside into our nasal cavity, and finally the lungs cannot filter it out, which means that the lungs will not be able to withstand this pressure in the end, and lung cancer will naturally come towards itself.

Second, this also tells us that we still need to have a good working environment <>

In fact, there are only two reasons for lung cancer, either the working environment is extremely harsh, there is a lot of dust, and the lungs cannot be filtered, or they take the initiative to find themselves to smoke and inhale nicotine into the lungs. Either way, in fact, we can avoid it, we can try not to look for some bad working conditions when looking for a job, and at the same time avoid smoking, smoking really hurts the lungs.

I think it may be due to his very poor daily eating habits, easy to eat some greasy and spicy food and sea cucumber and abalone, so after he eats these greasy foods, his body functions will change, and he often does not exercise.

Although I don't smoke, I am in an environment where others smoke, so I am prone to lung cancer.

This is because these people have bad lifestyle habits, often stay up late, often stay up late, often drink alcohol, and eat problems with food, so they get cancer.

There is a great correlation between smoking and the incidence of lung cancer, especially squamous cell carcinoma and small cell lung cancer in lung cancer. At the same time, the occurrence of lung cancer is also related to other factors, such as indoor air pollution, radon radioactive element contamination when decorating rooms; or insufficient combustion of indoor fuel, if wood is not fully burned after using wood in rural areas, the production of smoke will cause lung cancer. At the same time, the fumes generated by the kitchen can also cause lung cancer, so use a range hood or exhaust fan when cooking to remove polluted air.

In addition, air pollution is also an important factor in the occurrence of lung cancer, so industrial pollutant gases must be purified before they can be discharged into the atmosphere. Advocate green travel, recommend the use of public transportation, and reduce exhaust emissions. The occurrence of lung cancer is also very related to the immune status of the body, so the majority of people should maintain a happy attitude and reduce the pressure of life, so as to improve resistance and prevent the occurrence of lung cancer.

Three patients I knew had lung cancer.

Smoking is an important factor in lung cancer, but you can also get lung cancer if you don't smoke.

There are many causes of lung cancer, and it is not caused by a single factor.

1. People who smoke secondhand smoke are more likely to get sick than people who smoke.

2. There is a carcinogen called benzopyrene in the fume, which greatly increases the chance of lung cancer caused by long-term inhalation.

3. Familial inheritance, 4. Immune system diseases.

5. Air pollution.

6. People with emphysema and COPD are more likely to induce cancer.

Lung cancer is clinically manifested as cough, sputum production, chest pain, hemoptysis, dyspnea, chest tightness, shortness of breath, etc. Once lung cancer is diagnosed, it should be surgically removed as soon as possible, or adjuvant with radiotherapy and chemotherapy**.

There are many other factors that cause lung cancer, which can be roughly divided into four factors: genetics, radiation damage, air pollution, and low immunity.

Needless to say, air pollution includes both outdoor and indoor pollution. Outdoor pollution, such as atmospheric haze, industrial exhaust gas, automobile exhaust, etc., while indoor pollution is mainly only decoration pollution, kitchen fumes, second-hand smoke, etc.

Factors such as unbalanced nutrition, poor lifestyle, and endocrine disorders in a high-pressure environment will affect immune function, leading to low immunity, thereby increasing the risk of lung cancer.

Therefore, even if some people do not smoke, they may get lung cancer for reasons other than smoking.

Similarly, smoking causes cancer, which increases the risk of lung cancer, but it does not mean that lung cancer will definitely occur. Therefore, there will be cases of people who have smoked all their lives but do not get cancer. But this probability is very small, even if there is no cancer, it will be caused by smoking, and some people are lucky, thinking that they can smoke for a lifetime without incident, which is actually gambling with their lives.

In addition, in view of the high incidence of lung cancer and the difficulty of lung cancer, it is recommended that people with high-risk factors for lung cancer such as long-term smoking and family history of lung cancer should understand the early symptoms of lung cancer in advance, and then pay more attention to their own health, find lung cancer-related abnormalities, and go to the hospital for examination in time.
