Do you know the smoking index of lung cancer? Number of cigarettes per day x Years of smoking (smoking age)=smoking index. If a smoker's smoking index exceeds 400, the smoker is at high risk of lung cancer! For example, smoking more than 20 cigarettes a day, continuous smoking more than 20 years, and smoking index more than 400. The high-risk group of lung cancer with a smoking index greater than 400 must pay attention to the annual physical examination. Chest CT examination is helpful to early detection of early lung cancer.
