1.Stay away from tobacco: Smoking is the main risk factor for lung cancer, and smokers are recommended to use smoking cessation services and quit smoking.

2.Avoid or limit exposure to cancer-causing agents: Avoiding exposure to known cancer-causing agents (such as asbestos, air pollution, cooking oil fume, secondhand smoke, radon, arsenic in drinking water, etc.) may also be helpful.

3.Lung cancer screening: Citizens who meet the criteria for lung cancer screening can inquire about screening at hospitals under the Lung Cancer Early Detection Program to ensure early diagnosis and early treatment:

(1) Individuals with a family history of lung cancer, specifically, men aged between 50 and 74 years and women aged between 45 and 74 years whose parents, children, or siblings have been diagnosed as having lung cancer.

(2) Individuals with a history of heavy smoking, specifically, individuals aged between 50 and 74 years with a smoking history of 30 or more pack-years who are willing to quit smoking or who have quit smoking within the past 15 years.
