Why is lung cancer the first malignant tumor? What are the main causes of lung cancer?

Because lung cancer is not easy to control and difficult to control, all kinds of movements of the human body are inseparable from the normal operation of the lungs. The main cause of lung cancer is that patients like to smoke, drink alcohol, and live in an unclean air environment for a long time.

Because after getting lung cancer, it is very difficult, and the cost is very large, and there is generally no chance of it, so it has become the first malignant tumor, and the first lung cancer is mainly related to the genetic environment, irregular work and rest, and the occurrence of these factors.

The incidence of this disease is very high, and it is growing very fast, and the mortality rate is also very high; It may be caused by genetic factors, it may be caused by regular smoking and drinking, or it may be caused by air pollution, such as mining, car exhaust, and petroleum fuels.

The first is definitely smoking, nicotine and other substances in tobacco can easily cause lung cancer, the second is second-hand smoke or third-hand smoke, people nearby smoke, others will also be harmed, and the third is the process of industrialization, which makes the air turbid, and many harmful substances appear in the air!

1. Smoking factors: tobacco contains nicotine, benzopyrene and other carcinogens;

2. Environmental factors: such as soot combustion, oil smoke pollution, air pollution, automobile exhaust, industrial exhaust gas and haze, all contain carcinogens;

3. Occupational factors: people who are often exposed to chromium, nickel and asbestos are prone to lung cancer;

I think the main reason is smoking, because the nicotine in cigarettes is very harmful to the body.

The pathogenesis of lung cancer is not fully understood, but there is evidence that the occurrence of lung cancer is related to factors such as smoking, air pollution, occupational carcinogenic factors, diet, and genetics. In general, genetic and environmental factors are involved in the pathogenesis.

First, the main **.

1. Smoking: Smoking is the primary cause of the progressive increase in lung cancer mortality.

2. Occupational exposure: The occupational factors that have been confirmed to cause human lung cancer include asbestos, arsenic, chromium, nickel, beryllium, coal tar, mustard gas, chloromethyl ether, chlorometh ether, tobacco heating products, uranium, radium and other radioactive substances to produce radon and radon gas, ionizing radiation and microwave radiation.

3. Environmental pollution: In large cities with serious pollution, the amount of benzopyrene contained in the air inhaled by residents per day can exceed the content of 20 paper cigarettes, and the carcinogenic effect of paper cigarettes can be increased. Indoor passive smoking, fuel burning, and carcinogens produced during cooking.

4. Chronic infection of the lungs: For patients with tuberculosis and bronchiectasis, the bronchial epithelium metamorphoses into squamous epithelium during the process of chronic infection, and eventually becomes carcinogenic.

2. Predisposing factors.

1. Nutritional status: vitamin E and vitamin B2 deficiency and insufficiency are more prominent in lung cancer patients. Long-term deficiency of vitamin A, vitamin B, carotene and trace elements in food is prone to lung cancer.

2. Genetic factors: Genetic factors may also be high-risk factors for lung cancer, and lung cancer may have certain potential hereditary properties.

In today's society, the prevalence of lung cancer is increasing. What are the main causes of lung cancer?

1 Smoking Smoking is associated with the onset of almost all lung cancer patients. Paper smokers have a higher prevalence than cigar smokers and pipe smokers. Paper cigarettes contain various carcinogens, such as benzopyrene, which is the main carcinogen.

Passive smoking can also cause lung cancer. Women with husbands who smoke have a 50% increased risk of lung cancer.

2 Occupational carcinogenic factors The occupational factors that have been identified to cause human lung cancer include asbestos, inorganic arsenic compounds, dichlorome ether, chromium and other compounds, and the lung cancer mortality rate of smokers working in asbestos factories is 8 times that of general smokers and 92 times that of non-smokers and non-asbestos non-smokers. It can be seen that asbestos has a carcinogenic effect, and it also shows that smoking and asbestos have a synergistic effect on carcinogenicity.

3 Air pollution includes indoor small environment and outdoor large environmental pollution. For example, carcinogens that may be produced during indoor passive smoking, fuel combustion, and cooking. It has been reported that women who cook in smoky rooms have a 60% higher risk of developing lung cancer than women who are in rooms with no or no smoke, and the greater the risk of lung cancer with more exposure and longer years of exposure to cooking fumes.

Carcinogens exist in automobile exhaust gas, industrial exhaust gas, and highway asphalt in cities.

4 Genetic factors Not only is a person's development of lung cancer related to environmental factors, but genetic factors also play an important role. The main risk factors for lung cancer in young and middle-aged people are genetics and smoking.

Malignant tumors, namely lung cancer, are malignant, the incidence is relatively high, and after surgical pathological diagnosis, auxiliary radiochemical and immune cells are required, which can improve the survival rate, prolong the survival period, and make a clear diagnosis, and require biopsy pathological diagnostic examination. It is advisable to eat lightly and avoid spicy and greasy.

Hello, malignant tumors are also what we call cancer, malignant tumors are divided into early, middle and late stages, most of the early cancers have no obvious symptoms, generally cough, coughing up blood, low-grade fever, chest limit, dyspnea, etc. If you can't tell, it's best to go to the hospital and see a doctor in time.

The main differences between benign tumors and malignant tumors are roughly as follows:

1. The growth rate of benign tumors is slow, and the growth rate of malignant tumors is relatively fast;

2. Benign tumors do not metastasize, malignant tumors are easy to metastasize;

3. The texture of benign tumors is generally soft, most of them are separated by capsule and surrounding tissues, when palpating tumors, the tumors have a certain degree of mobility, the surface is smooth, and when they are surgically removed, they are easy to resect, and there are generally no systemic symptoms;

The surface of the malignant tumor is not smooth, the texture is hard, the boundary between the malignant tumor and the surrounding tissues is not clear, it is often relatively fixed, it is not easy to move, it is difficult to completely remove during surgery, and it is easy to **, and patients often have systemic symptoms such as emaciation, fever, and loss of appetite; You can take high-vitality health supplements such as Selenium Wellacon Chewable Tablets to improve immunity and alleviate these ***.

From the perspective of the harm of tumors to the human body, except for a very small number of benign tumors that can be transformed into malignant tumors, generally speaking, benign tumors only have local compression symptoms and do not endanger the lives of patients, while malignant tumors can quickly destroy the structure and function of surrounding tissues and organs, and when they metastasize extensively, they affect the function of the whole body, and finally cause dysfunction of various systems until failure.

The distinction between benign and malignant tumors is clear, but very early malignant tumors are often not easily distinguished from benign tumors. Benign tumors in the brain, heart and other parts are also a serious threat to life; Malignant tumors detected early can be operated on without affecting the patient's life.

Cough, sputum production, hemoptysis, low-grade fever, chest pain, shortness of breath, dyspnea.

Hello, the ** of lung malignancy needs to be formulated in combination with the specific pathological type and whether there is local or distant metastasis. If it is early, surgery can be done**, and the postoperative pathology is better or even chemotherapy can be avoided. However, if surgery is not suitable after a comprehensive examination, effective chemotherapy, radiotherapy, and targeted therapy should be used to control the disease.

It is recommended that you go to the local cancer hospital for systematic examination, clarify the type of pathology, and then choose a targeted plan**, which has a good effect. The principle is early detection and early **.
