Explain the causes of lung cancer

According to surveys, more and more people are suffering from lung cancer, which poses a serious threat to our lives. Do you know the causes of lung cancer? Regarding this issue, let our experts explain to you the causes of lung cancer.

What are the causes of lung cancer? The following is an introduction to the causes of lung cancer:

1. Indoor pollution (radon gas)

Smoking is the number one cause of lung cancer, but most people probably don't know that indoor radon gas pollution is the second largest cause of lung cancer after smoking. Epidemiological surveys and molecular biology experiments have confirmed that radon gas and its progeny are one of the main risk factors for lung cancer in humans. Lung cancer caused by radon and its progeny can account for 8% to 20% of the population suffering from lung cancer. The harm caused by radon gas to the human body is mainly due to the high indoor radon concentration that may exist in residences and workplaces. Usually, basements, houses adjacent to basements, air-conditioned rooms, office buildings with strong sealing, hotels, and houses built with building materials containing high radioactive elements are more likely to have high indoor radon concentrations. Therefore, experts recommend that in addition to paying attention to the selection of materials during construction and decoration, opening windows for ventilation in daily life is also helpful to reduce the harm of radon gas.

2. Occupational factors

There are many carcinogens in the working environment of certain occupations. The carcinogens that have been confirmed so far include asbestos, inorganic arsenic, dichloromethyl ether, chromium, mustard gas, soot, tar, polycyclic aromatic hydrocarbons in petroleum, heating products of tobacco, etc. In addition, glass fiber, artificial fiber, talcum powder, etc. are also speculated to be carcinogenic.

3. Other factors

Genetic factors, viral infections, and certain chronic lung diseases (such as tuberculosis, sarcoidosis, etc.) may also have a certain relationship with the occurrence of lung cancer.
