How long lung adenocarcinoma can live cannot be generalized, if it is early stage with regular treatment, the 5-year survival rate can reach 90%~95%, and the 5-year survival rate of intermediate or advanced stage is 10%-70%. If lung adenocellular carcinoma belongs to early stage and can be treated by surgery in time, the survival rate after surgery is relatively high, and the 5-year survival rate can reach 90%, or even more than 95%, and some patients may be clinically cured. If lung adenocarcinoma is not well staged, belongs to middle stage and has not developed distant metastasis, the 5-year survival rate after treatment is about 70%; if middle stage lung adenocarcinoma has begun to develop invasive lesions, the 5-year survival rate is about 30%; and the 5-year survival rate of advanced lung adenocarcinoma is about 10%. If lung adenocarcinoma can be diagnosed and treated early, the survival period of patients can be prolonged and the quality of life can be improved. After diagnosis, patients should seek medical treatment in time and under the guidance of professional physicians to avoid delaying the disease.
