Many people know that smoking is the main cause of lung cancer, and people who get lung cancer are basically "smokers" ,
However, after being diagnosed with lung cancer, some people will wonder: I don't usually smoke, why do I still smoke? What about lung cancer?
In fact, although smoking is the main cause of lung cancer, it is not the only cause. Smoking and lung cancer cannot be completely equated.
Even if you don’t smoke, it doesn’t mean you don’t smoke passively, which is often referred to as second-hand smoke and third-hand smoke. In daily life, you may also be exposed to many other carcinogens.

At the same time, there are more than these in cigarette smoke, there are also some irritating substances,
such as Nitrogen compounds and olefinic substances can irritate the mucous membranes of the eyes, nose, throat and other organs, and irritate the respiratory mucosa , causing acute or chronic bronchitis Inflammation and other diseases .

Once If inhaled, they will accumulate in the lungs. If you stay in haze for a long time, the more harmful substances will accumulate in the lungs, the easier it will be to cause lung cancer.
Oil fume pollution
