Never smoked, but found out lung cancer. What are the other causes of lung cancer?

Lung cancer is still a malignant tumor with a high morbidity and mortality rate in the past two years. Once lung disease appears, it will have a significant impact on daily life and health. There are many reasons for lung cancer. Long-term smoking is one of the most harmful behaviors. However, we often find that some people who do not smoke are still diagnosed with lung cancer.

40-year-old Ms. Liu is an ordinary office worker. Since she gave birth to a child, she can only quit her job and be a housewife at home. Every day, except for trivial things such as washing and cooking, cleaning up housework, picking up children, etc., there is basically nothing else. Things can be done. But recently I always have symptoms of chest tightness and coughing. I thought it was only caused by being too tired recently, but I did not expect the symptoms have not been relieved. On the contrary, the symptoms have become more and more serious. Even the breathing has been affected. Ms. Liu, who is not relieved, hurry up I went to the hospital for a full-body examination, and was found to have a disease like lung cancer.

But Ms. Liu never understood how she was diagnosed with lung cancer because she never smoked. In fact, it is not only smoke that hurts the lungs.

01, Eat deep-fried and grilled food often

I usually like to eat some deep-fried, fried and roasted foods. Such a long-term diet will actually have a great impact on the health of the lungs. Studies have confirmed that eating more fresh vegetables and fruits will help the lungs to a certain extent. It can reduce the risk of lung cancer. Foods such as deep-fried and grilled are not only of low nutritional value, but after high-temperature frying, strong carcinogens are easily produced in them, which can easily increase the incidence of cancer. Diseases such as lung cancer are no exception.

02, Do not wear a mask when you go out.

If you often go in and out of the haze and don't wear a mask, it will cause great damage to the health of the respiratory system. The main reason is that the smog contains a large amount of dust and some harmful substances, which are easily adsorbed in the lungs when entering the lungs, which will cause lung diseases for a long time, and even increase the incidence of lung cancer.

03, Often depressed and angry.

Being depressed all day, or even losing your temper at every turn, will seriously affect the harmony of the family, and if such emotions accumulate in the heart for a long time and cannot be released, it will cause lung qi stagnation and alveolar expansion, thereby accelerating lung damage. Gradually develop into lung cancer over time.

Therefore, smoking is not the only cause of lung cancer. The above three factors cannot be ignored. Lung cancer is also a chronic disease. If you don’t pay attention to it, there will be no abnormalities in your body for a while, but with time The accumulation of disease will slowly appear.

Cigarettes are still one of the main causes of lung cancer. The smoke produced after a cigarette is lit contains more than 3000 toxic chemicals. According to statistics, smoking 10 cigarettes a day increases the incidence of lung cancer by 13 times; if you smoke 20 cigarettes a day, the incidence of lung cancer increases by 20 times; smoking 40 cigarettes a day increases the incidence of lung cancer by 65 times. The smoke produced after the cigarette is lit contains more than 3000 toxic chemical substances, the most important of which are nicotine, carbon monoxide, cyanide, a variety of carcinogens, radioactive isotopes and heavy metal elements in cigarette tar. The carcinogens produced by tobacco burning include benzopyrene, nitrosamines, β-naphthylamine, cadmium, and radioactive polonium. There are also cancer-promoting substances such as phenolic compounds. The death rate of passive smoking and lung cancer in non-smokers caused by the husband’s smoking is 1-2 times higher than that of the non-smokers.

Smoking is internationally recognized as one of the most important factors causing lung cancer. The death of smokers from lung cancer is about 10 times more than that of non-smokers. 70% to 80% of male lung cancer is caused by smoking, and about 30% of female lung cancer is attributed to smoking and passive smoking. The earlier you smoke, the greater the risk of lung cancer. The death rate of lung cancer for people who have been smoking for 60 years is about 100 times higher than that for people who have been smoking for 20 years. All, it is still necessary to quit smoking as soon as possible and restore a healthy life.
