How to effectively prevent lung cancer? Pay attention to these three points to prevent lung cancer

In terms of lung cancer prevention, the first thing to do is to try to control smoking. Clinically, almost all lung cancer patients are more or less related to smoking. Sometimes it is the main cause of lung cancer, but this is not absolute. However, in any case, quitting smoking is the key to preventing lung cancer. The following is an introduction to the prevention of lung cancer:

1. A large proportion of patients with a high incidence of lung cancer have a history of tuberculosis. Tuberculosis is a chronic infectious disease that is prone to occur in young people, and 80% of tuberculosis occurs in the lungs. Tuberculosis was once the main killer of mankind, claiming the lives of hundreds of millions of people. Clinical experience shows that many old tuberculosis lesions will become the cradle of lung cancer in the future. Some patients had tuberculosis in their early years, and later found that the nodules gradually increased, and the final pathological diagnosis was scar cancer. my country is one of the 22 countries with a high burden of tuberculosis in the world, with more than 400 million infected people. This huge population of tuberculosis-infected people may have a causal relationship with the high incidence of lung cancer in my country in recent years.

2. People with a family history of cancer. According to relevant data, many tumors have obvious family clustering characteristics, including lung cancer, colon cancer, breast cancer, etc. In a study conducted in Japan, researchers divided patients whose immediate relatives had lung cancer and those who had no family history of lung cancer into two groups. The former had twice the chance of getting the disease as the latter. The hereditary nature of lung cancer is more obvious in women. Clinical experience shows that people with other tumors in their family have a higher risk of developing lung cancer than those without a family history of tumors.

3. Smokers and passive smokers. The occurrence of lung cancer is closely related to people's living habits, such as smoking. Epidemiology and scientific experiments have successively proved that cigarettes contain 42 carcinogens, and lung cancer is closely related to smoking. Studies have shown that the incidence of lung cancer in long-term smokers is 10-20 times higher than that of non-smokers. In addition, among patients who do not smoke but suffer from lung cancer, 25% are passive smokers. The harmful substances inhaled by passive smoking are often more powerful than active smoking. The younger the smoker is, the more he smokes, and the longer he smokes, the more dangerous it is; the risk of lung cancer in female smokers is twice that of male smokers.

With the development of society, the number of patients with lung cancer caused by special occupations is increasing. It is recommended that such people pay attention to strengthening protection in their daily work. At the same time, they should pay attention to physical exercise in their daily life to fundamentally improve their body's disease resistance.
