The survival time of early stage of invasive lung adenocarcinoma is related to the size and location of the tumor, whether it receives scientific and effective treatment, the choice of treatment plan, and other factors, and there are individual differences. Invasive lung adenocarcinoma is a pathological type of lung cancer and survival time varies from person to person. The 5-year survival rate can reach more than 60%-70% after radical surgery for early stage lung adenocarcinoma. If the patient has poor heart or lung function and cannot tolerate surgery, most patients may survive within 2-3 years. Intermediate to advanced invasive lung adenocarcinoma requires a combination of treatment including surgery, radiotherapy and chemotherapy, and most patients have a survival period of 2 years or less. Any time you find out you have lung cancer, don’t be pessimistic and depressed, you should seek the guidance of a specialist as early as possible and actively receive treatment, which will help a lot to improve the cure rate.
