What are the causes of lung cancer?

Do you know what causes lung cancer? Many patients do not know about the causes of lung cancer. So what are the causes of lung cancer? Let's take a look!

Causes of lung cancer:

1. Chronic diseases: Many data show that cancer is prone to occur on the basis of chronic scars. Lung cancer can occur on the basis of tuberculosis scars, which is called "scar cancer".

2. Microbial infection: Although most tumors are not contagious, it has been confirmed that certain RNA viruses such as HTLV-1 and HTLV-2 viruses and human immunodeficiency virus (HIV) can cause leukemia, lymphoma and multiple angiosarcoma, respectively.

3. Chemical carcinogens: 3,4-benzopyrene (benzopyrene for short) has a strong carcinogenic effect and can cause skin cancer and lung cancer. The lung cancer mortality rate in many industrial cities is related to the content of benzopyrene in the air. Arsenic can cause skin cancer, lung cancer and liver cancer. There have been many reports on occupational cancers caused by arsenic compounds, many of which are primary cancers in multiple parts of the body. In addition to the above two, the recognized chemical carcinogens include asbestos, chromium, nickel, coal tar, mustard gas, isopropyl oil, mineral oil, dichloromethyl ether, chloromethyl methyl ether, etc.

The above are the causes of lung cancer. I hope that through the experts' introduction, you will have a new understanding of the causes of lung cancer. If you have any questions about the causes of lung cancer, please consult our online experts, who will give you detailed answers.
