Whether multiple lung adenocarcinoma is curable or not cannot be generalized, it needs to be analyzed according to the specific stage, patient’s physical condition, gene mutation situation and so on. Lung adenocarcinoma is a kind of lung cancer, the cause of which is still unclear and may be related to smoking and air pollution. If multiple lung adenocarcinomas are confined to one lung lobe and the lesions are relatively limited, the patient can cooperate with the doctor for surgical treatment, and there is a certain chance of cure. If the patient is in the middle or late stage of the disease, comprehensive treatment, such as radiotherapy, immunotherapy, targeted therapy, etc., is usually needed, which is usually not a good cure. Although the middle and late stage of multiple lung adenocarcinoma is not curable, the progress of the disease can be effectively controlled, so as to alleviate the uncomfortable symptoms caused by the disease, such as hemoptysis, dyspnea, pain and so on. As for the prognosis of multiple lung adenocarcinoma, the later the stage, the worse the prognosis and the lower the survival rate, but it is advocated that patients should adjust their mindset and actively cooperate with doctors for early treatment. It is recommended that patients with multiple lung adenocarcinoma should consult regular hospitals and cooperate with doctors according to their actual conditions. They should also pay attention to developing good living and dietary habits, and should also pay attention to regular medical checkups.
