The reason why people get lung cancer even though they don't smoke

Even non-smokers can develop lung cancer, and the reasons may involve environment, genetics, lifestyle, etc. If you have a persistent cough, chest tightness, or abnormal weight loss, you should go to the hospital for a check-up.

Lung cancer is not necessarily caused by smoking. In fact, human lung cells may mutate when exposed to external stimuli, and genetic factors, air pollution, indoor harmful gases (such as long-term exposure to oil smoke) and radiation and other environmental carcinogens may all lead to the occurrence of lung cancer. Studies have shown that some people who have never smoked are also at risk of developing lung cancer due to family history or specific gene mutations, which is especially common in female non-smokers.

If you live in an area with poor air quality, long-term inhalation of particles in the haze may damage your lung health; frequent use of high-temperature frying or stir-frying stoves at home without proper ventilation will also produce a large amount of oil fume particles, which may accumulate in the lungs and become a hidden danger. At the same time, occupational exposure, such as asbestos, radon gas or other chemicals, will also increase the probability of lung cancer.

To reduce the risk, it is recommended to avoid exposure to air pollution and secondhand smoke as much as possible, use a range hood and ensure ventilation when cooking at home. If there is a family history of lung cancer, it is recommended to have regular physical examinations, especially low-dose spiral CT screening, so as to detect potential problems early and strive for the best treatment window.
