Hypofractionated lung adenocarcinoma has a higher degree of malignancy and there is a possibility of recurrence, but it is not 100% recurrence. Hypofractionated lung adenocarcinoma is poorly differentiated lung adenocarcinoma. The degree of differentiation reflects the difference between tumor cells and normal tissue cells, and the lower the differentiation, the higher the degree of malignancy, and the more likely to metastasize, but it is not 100% recurrence. If patients are treated in time at the early stage of the disease and all the lesions are removed, the tumor will not necessarily recur after surgery. For patients with hypofractionated lung adenocarcinoma, the prognosis is related to the tumor stage, treatment plan and the patient’s physical status. Patients need to develop good living habits and dietary habits after surgery and have regular medical checkups. If they have the habit of smoking, they need to quit in time. Eat more nutritious food, more fresh fruits and vegetables and lean meat. Hypofractionated lung adenocarcinoma has a higher chance of recurrence, but it is not 100% recurrence, and patients should keep a good mood.
