What causes lung cancer and what causes it?

The causative factors of lung cancer are not fully understood, and a large number of medical data show that the risk factors of lung cancer are related to the following points:

Smoking: Almost all lung cancer patients develop smoking-related. Cigarettes contain a variety of carcinogens, and the incidence of lung cancer in smokers is 10 times higher than that of non-smokers, and the incidence of lung cancer is higher in those who smoke a lot, which is 20 times higher than that of non-smokers.

Environmental factors: Environmental pollution and air pollution can easily lead to a high incidence of lung cancer, especially radon, tin, arsenic, toluene and other pollution.

Occupational factors: Long-term exposure to radioactive substances such as uranium and radium and their derivatives can easily induce cell carcinogenesis.

Chronic lung diseases: Patients with tuberculosis, silicosis, pneumoconiosis and other diseases have a higher incidence of lung cancer than normal people.

Intrinsic factors in the human body: such as familial heredity and decreased immune function, metabolic activity, endocrine dysfunction, etc.

First of all, the risk factors of lung cancer are smoking and secondhand smoke, insomnia, ionizing radiation, which may be caused.

There is also air pollution.

In addition, there are occupational factors, long-term exposure to radioactive substances and their derivatives are carcinogenic.

Then there are chronic diseases of the lungs, such as tuberculosis and pneumoconiosis, which may coexist with lung cancer, and the incidence of these diseases will increase.

In addition, familial hereditary and decreased immune performance, metabolic activity, endocrine dysfunction, etc., may induce the occurrence of lung adenocarcinoma.

1.Radioactive uranium and fluorite miners are exposed to the noble gas radon, decaying uranium by-products, etc.

2.In patients with chronic lung infection such as tuberculosis and bronchiectasis, the bronchial epithelium may metamorphose into squamous epithelium during the slow infection process, and eventually cause carcinogenesis, but this kind of situation is relatively rare.

3.Internal factors: Familial, genetic, and congenital factors, as well as decreased immune function, metabolic, and endocrine dysfunction may also be high-risk factors for lung cancer.

4.Smoking: Smoking is considered to be the most basic risk factor for lung cancer.

5.Occupational and environmental exposures: It is estimated that up to 15% of lung cancer patients have a history of environmental and occupational exposures.

6.Air pollution is associated with a high incidence of lung cancer in industrially developed countries.

Excessive alcohol consumption. Whether it is alcoholic beverages, or beer, wine, and spirits, the risk of developing cancers of the mouth, pharynx, and throat increases significantly as intake increases. If you must drink it, men should not exceed 2 servings per day.

Excessive smoking. Smokers have a 7-11 times higher risk of cancer than non-smokers. More than 30% of cancers such as lung cancer, laryngeal cancer, and esophageal cancer are closely related to smoking.

Craving of red meat. Diets that are too high in red meat may lead to multiple cases of pancreatic cancer, prostate cancer, etc. Consume less than 500 grams per week and eat as little processed meat products as possible.

Excess salt. Table salt and salted foods will increase the incidence of stomach cancer. The total daily salt intake should be less than 6 grams.

Lampblack. Often in the kitchen, there will be some oil fumes, if you are exposed to oil fumes for a long time, the risk of lung cancer will also be greatly increased. The survey found that young and middle-aged women who are exposed to high-temperature oil fumes while cooking in the kitchen for a long time will increase their risk of lung cancer by 2-3 times.

Therefore, female friends must pay attention to the cleanliness and ventilation of the kitchen, reduce high-temperature frying, and don't be too superstitious about range hoods.

Overcast days. Gloomy days are even more likely to induce lung cancer than tobacco. The suspended particles in the air on hazy days are difficult to disperse and are easily absorbed by the human body, and these particles may directly adhere to the respiratory tract and lung lobes, causing rhinitis, bronchitis and other diseases; In the long term, this can lead to lung cancer.

The incidence of lung cancer is the same as many tumors, its cause is not very clear, there are genetic, environmental, nutritional problems are related, the first recognized lung cancer, the main risk factor is smoking, smoking more than 400 years, that is, smoking 20 cigarettes a day for more than 20 years, such a patient thinks that the risk of lung cancer is very high, and there are some occupational carcinogenic factors, such as patients who touch asbestos, are prone to this pleural tumor. The third is air pollution, such as smog days, which is a factor in the high incidence of lung cancer, and there is also exposure to ionizing radiation, which is prone to lung tumors.

The cause of lung cancer is very complex, and there is no definite conclusion, but there are several factors that we should pay special attention to. The first is environmental factors, especially tobacco nowadays, whether it is self-smoking or second-hand smoke, which is an obvious factor causing lung cancer. For example, cooking at home, the oil smoke produced or the exhaust fumes of cars in our air, this kind of air pollution is a factor that cannot be ignored to cause lung cancer.

Our genetics also play a big role in this.

Common lung cancers** mainly include:

2. Chronic diseases of the lungs: long-term pulmonary bronchitis, anti-tuberculosis, etc.;

3. Occupational factors: long-term underground work or long-term exposure to harmful substances such as paint, petroleum and rubber may cause lung cancer;

4. Air pollution: fine particulate matter may cause lung cancer;

5. Genetic factors;

6. Radon.

There are some risk factors for lung cancer, the most important ones are smoking, and the other is occupational exposure history, such as exposure to some heavy metals and dust, such as the exposure history of some occupations, as well as the disease history of malignant tumors. The other is a history of lung cancer in a first-degree relative. What is a first-degree relative, that is, one's own parents, these first-degree immediate relatives.

The history of lung cancer in the first-degree family is a relatively high-risk factor. Smoking is also a very important factor, and there is also a history of exposure to dust, which is an important risk factor.

The causes of lung cancer are very complex, and smoking is also one of the predisposing factors. Once diagnosed. The preferred option is surgery.

Then, according to the pathology after the operation, the follow-up **, chemotherapy, radiotherapy, etc. are decided. Patients are advised to go to a regular cancer hospital for surgery immediately**.

Lung cancer is a multifactorial disease with both environmental and individual causes. Lung cancer has a certain genetic predisposition, not that parents who have lung cancer will be passed on to the next generation, but that the susceptibility to lung cancer in the gene will be inherited, such as sensitivity to the risk factor of smoking. Environmental factors such as air pollution, smoking, negative emotions, etc., are a combination of many factors.

Hello, the current cause of lung cancer is not clear, there are genetic factors, acquired factors, such as smoking, environmental pollution, and genetic mutations.

The cause of cancer is unknown, but smoking is the leading cause of lung cancer. A large number of clinical studies have shown that more than 85% of lung cancer patients are related to smoking, and people who smoke are 16 times more likely to develop lung cancer than non-smokers. The cause of lung cancer is related to the age of the first cigarette and the amount of cigarettes smoked, the younger the age of the first smoker, the greater the amount of cigarettes, and the greater the chance of developing lung cancer.

In addition, there are some secondary factors, such as environmental pollution, occupational diseases, ionizing radiation, kitchen fumes, etc.

Occupational carcinogenic factors, there are many occupations nowadays, and some occupations will be exposed to some carcinogenic factors, which can cause lung cancer. These carcinogenic factors include asbestos, inorganic arsenic compounds, dichloromethane, soot, tar, etc.

The causes of lung cancer have been proven to be smoking, genetics, environmental pollution, etc.

Long-term inflammation, air pollution, dust, staying up late, smoking and drinking, etc.

The most advanced hormones that cause lung cancer mainly include: 1. Smoking: it is the most dangerous carcinogenic factor for lung cancer, and the incidence rate of smokers is 10-20 times higher than that of non-smokers; 2. Air pollution:

Pollution from oil smoke, automobile exhaust and small substances such as asbestos and nickel in the air is also a high incidence factor for lung cancer. 3. Radiation: including iatrogenic and non-iatrogenic excess radiation; 4. Heredity: family history of tumor and genetic predisposition; 5. Diet:

Such as vitamin A deficiency, etc.

The first is the outdoor haze, then the indoor haze, and then the inner haze. Five gas is outdoor air pollution, the people are concerned, has been listed as a class of carcinogens by the World Health Organization, the second gas is tobacco smoke, which includes first-hand smoke, second-hand smoke and third-hand smoke, the same tobacco has long been listed as a class of carcinogens, the third gas is kitchen fume, our current cooking process, our kitchen environment, our cooking methods, our secondary use of practical oil, frying, frying, barbecue, are an important factor in indoor kitchen fume pollution, These are all related to lung cancer.

The fourth gas is the house decoration, indoor air pollution caused by house decoration, also known as volatile harmful gases, collectively known as VOCs, representing radon, benzene and formaldehyde, and radon has long been listed as a class of carcinogens by the World Health Organization, the fifth gas is what the people call angry, long-term love to sulk, we also call it "cancer character", so we also say, as long as you stay away from the "three haze and five gases" you can stay away from lung cancer.

Lung cancer is particularly common, but smoking is the most common.

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.

Hello, lung cancer is generally divided into three types, lobular pneumonia, lobar pneumonia and myopia lenses, small cell lung cancer is generally more malignant, it is difficult to be thorough, you can go through surgery, late chemotherapy, **.

Lung cancer is a very common malignant tumor of the respiratory system, generally speaking, the main symptoms of lung cancer are cough, sputum production, hemoptysis, and some have no obvious symptoms in the early stage. For example, common smoking is one of the most important causes of lung cancer, of course, there are many non-smokers who get lung cancer, in addition, such as environmental pollution, diet, chemical pollution, car exhaust, etc., may contain factors that can easily lead to lung cancer.

In our research, we found that lung cancer also has genetic factors, there is a phenomenon of family aggregation, and gene mutation is also an important reason, after the diagnosis of lung cancer, it can generally be operated on**, mainly surgery**, and can be combined with adjuvant radiotherapy, chemotherapy and other comprehensive ** after surgery to control the development of the disease, and targeted drugs can also be used**.

There are many causes of lung cancer, the main ones are the following:

Clause. 1. Active smoking. Because tobacco contains a lot of carcinogens, people who smoke for a long time are prone to lung cancer. If you quit smoking in time, the morbidity and mortality rate of lung cancer will be greatly reduced after ten years, so it proves that tobacco and lung cancer are closely related.

Clause. 2. Passive smoking. Passive smoking is the inhalation of tobacco by others in an environment with poor air circulation. Second-hand smoke is more harmful to the human body, and the carcinogens in the side smoke stream are stronger.

Clause. 3. Oil smoke. For people who cook often, especially when they are often stir-fried, after the oil is more than one, a large number of carcinogens will be produced in it, and lung cancer will also be induced after entering the respiratory tract.

Clause. 4. Air pollution, such as smog, car exhaust, etc.

Clause. Fifth, if you are often depressed and depressed, it is not good for your body.

The common causes of lung cancer are as follows:

1. Smoking: The primary cause of lung cancer is smoking, and many lung cancer patients smoke for a long time, and the larger the amount of smoking, the longer the carcinogenic rate.

Second-hand smokers: If second-hand smokers inhale second-hand smoke for a quarter of an hour every day, their cancer rate is the same as that of smokers, so in addition to ensuring that they do not smoke, they must also ensure that they stay away from second-hand smoke.

3. Stay away from occupations that can cause cancer: Many people have a lot of carcinogens in their working environment because of the particularity of their occupations, such as tar, petroleum, asbestos and inorganic arsenic, etc., if there are no preventive measures for long-term exposure, it will also greatly increase the chance of suffering.

4. Indoor decoration pollution: This condition is also one of the causes of lung cancer. Many people are becoming more and more environmentally friendly, but the pollution of interior decoration has become serious enough to endanger human health.

The incidence of lung cancer is related to the following factors: smoking; occupational carcinogenic factors; Air pollution; Ionizing radiation; Diet & Nutrition; Tuberculosis; activation of certain oncogenes and inactivation of tumor suppressor genes; Factors such as viral infection, mycotoxins, weakened immune function, endocrine disorders and familial heredity may also play a certain role in the occurrence of lung cancer.

The first reason is smoking, most of them in China are smokers;

Air pollution is also one of the causes;

Career choice, which is also related to the profession;

Then there is heredity;
