What are the factors that cause lung cancer? In recent years, the incidence and mortality of lung cancer have continued to rise, so it is particularly important to do a good job in lung cancer prevention. To understand the prevention of lung cancer, you must first know the cause of lung cancer. Only by understanding the cause of lung cancer can you better prevent it. So what are the factors that cause lung cancer? Let our experts introduce it to you in detail below.

1. History of respiratory diseases: A history of lung diseases (asthma, chronic obstructive pulmonary emphysema, pneumonia and tuberculosis) is a risk factor for lung cancer, among which tuberculosis is the most closely related.

2. Low body mass index: A lower body mass index (BMI = weight/height 2) (less than 20) increases the risk of lung cancer.

3. Smoking: Smoking is defined as smoking more than one cigarette a day for more than six consecutive months. Studies have found that men who smoke more than two packs a day have a 20.4 times higher risk of lung cancer than normal people. The more you smoke and the longer you smoke, the greater the risk. The risk of passive smokers is related to the number of years of passive smoking.

4. Low intake of fresh vegetables: In life 10 years ago, consuming more vegetables and a moderate amount of fresh fruits had a protective effect on male lung cancer; the greater the intake, the more obvious the protective effect. Although the effect of consuming more vegetables on women is not as obvious as that on men, there is also a protective trend. In addition, sour (vinegar) foods, spicy foods, and onion and garlic foods have a protective effect on lung cancer, while fried foods and pickled foods will increase the risk of disease.

5. Kitchen fumes: Female lung cancer is closely related to kitchen fumes.

6. Air pollution: If there were pollution sources (smelting, chemical industry, coking) within 500 meters of the residence 10 years ago, the risk of lung cancer would increase. Occupational exposure to dust and asbestos dust would also significantly increase the risk of lung cancer. In addition, the impact of indoor pollution on lung cancer cannot be ignored.

7 Psychological factors: poor psychological adaptability, long-term mental depression, and significant type A personality (quick actions, impatience, strong aggressiveness, and irritability) will increase the risk of lung cancer.

The above is a detailed introduction to the factors that cause lung cancer. I believe you have already understood it.
