Lung adenocarcinoma is a common pathological type of lung cancer, and the average survival period of patients with advanced stage is about one year, but the survival period of each patient is different, which is affected by their physical condition, treatment effect and other factors. There is actually no standard answer to the survival period of advanced lung cancer patients. Each patient’s physical condition, treatment effect and severity of the disease are different. Some patients have better health condition and although their disease is advanced, after active treatment, they can effectively control their disease and their survival period is usually longer. Some patients are in poor physical condition, but after active treatment, the effect is very good, then their survival period will not be very short. Some patients are in good health, but the treatment effect is very poor, then the disease progresses and the health condition declines sharply, so the survival period of such patients will definitely be short. There are also some patients who are in poor physical condition and have poor treatment effect, so the survival period of this kind of patients is definitely very short. In any case, although lung cancer is advanced, it is necessary to maintain a good state of mind and take active treatment measures in order to prolong the life of patients.
