What are the causes of lung cancer in life? There are four high-risk factors for lung cancer

Lung cancer is very harmful to people. Once you get the disease, it will have a serious impact on your life. If we can understand the cause of lung cancer in time and take targeted preventive measures, we can avoid the erosion of lung cancer. So, what are the causes of lung cancer in life?

Causes of lung cancer:

1. Diet and nutrition

The intake of natural vitamin A, beta-carotene and trace elements (zinc, selenium) in food is negatively correlated with the occurrence of cancer, the most prominent of which is lung cancer. The deficiency and insufficiency of vitamins E and B are more prominent in lung cancer patients.

2. Air pollution

Industrial waste gas, automobile exhaust gas, and road asphalt in cities all contain carcinogens. Statistics show that the incidence of lung cancer in cities is significantly higher than in rural areas.

3. Smoking

Smoking is recognized as an important risk factor for lung cancer. More than 3/4 of lung cancer patients are heavy smokers. The earlier the age of smoking, the longer the smoking period, and the greater the amount of smoking, the higher the mortality rate of lung cancer. The risk of lung cancer in smokers gradually decreases as the number of years of quitting smoking increases. Cigarettes contain more than 10 carcinogens, such as benzopyrene, nicotine, nitrosamines, and trace amounts of arsenic, which can cause the loss of normal bronchial epithelial morphology, accompanied by atypical cytological changes.

4. Passive smoking

The latest research shows that if secondhand smokers inhale secondhand smoke for 15 minutes a day, their chances of developing lung cancer are the same as those of smokers. There are more than 100 lung cancer-inducing genes in the human body, and Asian women carry several common genes, so Asian women are more likely to develop lung cancer. In addition to not smoking, they should also try to stay away from secondhand smoke.

The causes of lung cancer in life are introduced here. You should know that the occurrence of lung cancer is inseparable from people's daily life, especially the factors of smoking. Therefore, we must prevent the occurrence of lung cancer in life, stay away from the factors that cause lung cancer, and ensure our own health.
