Beike founder Zuo Hui passed away. He didn’t smoke or drink. Why did he get lung cancer?

In daily life, when a person suddenly becomes seriously ill, many people will sigh: Why did he suddenly become seriously ill if he didn't smoke or drink.

In the eyes of most people, serious illness is linked to bad living habits. Bad living habits include smoking, drinking, staying up late, irritability, overeating, etc. But in fact, bad living habits only increase the chance of getting sick. Maintaining good habits does not mean that you will never get seriously ill.

The cause of lung cancer is not yet clear. In recent years, lung cancer is one of the malignant tumors with the fastest growing morbidity and mortality. According to relevant reports, the incidence and mortality of lung cancer have increased significantly.

According to data from the WHO's International Agency for Research on Cancer: China has the largest number of new cancer cases in the world in 2020, approximately 4.57 million, among which lung cancer ranks first in the number of new cases. In 2020 alone, the global new incidence rate of lung cancer will be as high as 2.2 million, while in China, the number of new cases of lung cancer in 2020 will reach 820,000, and the number of deaths will be 710,000. These statistics are sobering.

The causes of lung cancer mainly consider the following factors: 1. External factors.

External factors include living habits, environmental pollution and occupation, natural factors or iatrogenic factors, and past medical history.

Among lifestyle habits, smoking is currently considered to be the most important high-risk factor for lung cancer. This is why smoking is always associated with lung cancer.

Tobacco is classified as a category 1 (highest level) carcinogen in the list of carcinogens of the World Health Organization's International Agency for Research on Cancer. Smoking produces some chemicals that are very harmful to the human body. Long-term smoking often causes certain damage to the respiratory tract. Therefore, smoking is harmful to health and is not a simple slogan.

Environmental pollution and occupation refer to the fact that practitioners in some specific highly polluted environments often have a greater incidence of disease. For example, in the working environment of some mineral production and processing, long-term exposure to air pollution and carcinogens will cause greater harm to the human body.

Natural factors or iatrogenic factors, such as ionizing radiation, X-rays, radionuclides, and ultraviolet rays. The lungs are organs that are more sensitive to radiation.

Previous medical history, some past medical conditions or chronic medical conditions may also lead to cancer. 2. Internal factors.

Intrinsic factors include genetic factors and endocrine factors. The human body is a complex ecosystem, and the correlation between genes and diseases is a complex research subject. If one day we can determine the correlation between all diseases and genes, it may be possible to intervene in the occurrence of diseases in advance.

No matter what, if you want to have a healthy body, do as much as possible within the controllable range, such as maintaining good living habits, good eating habits, maintaining a good mood, and avoiding contact with Some dangerous substances. By doing this, we can reduce the probability of sudden serious illness as much as possible.

If unfortunately you are seriously ill, actively cooperating with treatment is the only measure we can take.

Finally, sincerely: Smoking and drinking are harmful to health. For the sake of your family and yourself, please smoke less and drink less.
