There are six other causes of lung cancer besides smoking

Many studies have shown that smoking is the most important cause of lung cancer, but in addition to cigarettes, there are six other risk factors for lung cancer. 

Radon radiation exposure. 

In the United States, the annual number of cases of lung cancer caused by radon radiation is about 20 000, which is the main cause of lung cancer among non-smokers. Radon is a natural radioactive gas, the main sources of home for building materials, soil precipitation, outdoor air drifting, heating and natural gas release from kitchen equipment, and so on. 

Radon levels in outdoor air are generally safe, but in homes or other buildings radon may accumulate to dangerous levels. 

As radon cannot be seen, smelled or tasted, a radon test should be conducted by a professional organization before moving into a new home. 

Asbestos fiber exposure. 

The American Cancer Society points out that inhaling or swallowing asbestos fibers for a long time can cause serious damage to lung cells, which in turn can lead to lung cancer. Persons working in asbestos-related occupations must be strictly guarded. 

Exposure to other carcinogens. 

The study found that arsenic, diesel exhaust, silica, chromium, nickel, beryllium, cadmium, tar and soot may increase the risk of lung cancer. The American Cancer Society recommends that exposure be kept to a minimum if these carcinogens are present in the workplace. 

Air pollution. 

The American Lung Association suggests that all kinds of particulate matter, including acids, compounds, metals, and dust, can harm lung function, especially microparticles. Because they can penetrate deep into the lungs, or even into the blood, the risk of cancer is even higher. 

Studies have shown that high levels of air pollution in residential areas, for example, close to roads with heavy traffic, can increase the risk of lung cancer. 

Infected with HIV virus. 

The National Cancer Society says people infected with HIV are more than twice as likely to develop lung cancer as those who are not infected with HIV. Some researchers speculate that this may be caused by HIV infection caused by the immune suppression, weakened immune system, causing inflammation and so on. 

Family history. 

Those with one parent or sibling who had lung cancer doubled their cancer risk compared with those without a family history of cancer. If a close relative has lung cancer at an early age, his or her family will have a higher risk of lung cancer. 

A review of research published in KuaiBao Oncology suggests that it may be the result of a combination of genetic and environmental factors.
