In the early stage of lung cancer, it is relatively common to survive 20 years after surgery. If early lung cancer is detected and early radical surgery is performed in time, it is very helpful for the survival rate of lung cancer patients, some of them can reach more than 95%, so surviving 20 years is not a big problem. Therefore, it is very important for early detection and early treatment of lung cancer. Regular check-ups are very helpful to detect early lung cancer. Try to have a comprehensive check-up once every 3 months or 6 months, which is very helpful to detect cancer. In addition, you must not smoke, because smoking has a great impact on lung cancer, especially it is easy to cause the recurrence of lung cancer. Therefore, you must not smoke. After quitting smoking, you can greatly reduce the prevalence of lung cancer, especially if you quit smoking for more than 5 years, the prevalence of lung cancer will be reduced to about the same level as normal people.
