In the late stage of lung cancer, how long can cancer cells live after spreading?

How long can lung cancer patients live? It depends on the stage of finding lung cancer. Then lung cancer can be divided into stages, I, II, III, IV and different stages.

Stage I indicates early lung cancer, and stage IV indicates metastasis, which is advanced lung cancer. The survival time of lung cancer in different stages is different.

Stage ⅰ lung cancer has the longest survival time. We say that the five-year survival rate is usually above 80% in stage I, about 70% in stage II, about 40% ~ 50% in stage III and about 20% in stage IV. Therefore, different patients have different survival times according to different stages.

If it is found to be advanced lung cancer at first, it may take six months to a year if it is not treated. If it is early lung cancer, he will have no problem after treatment and can return to a completely normal life.
