Early-stage invasive lung adenocarcinoma can be treated with comprehensive treatment mainly by surgery, supplemented by chemotherapy or targeted therapy after surgery. Early infiltrative lung adenocarcinoma usually refers to lung adenocarcinoma in which the tumor does not invade more than 5mm into the surrounding tissues and there is no metastasis from other parts of the lung. The tumor can be removed by radical surgery. Tumor stage I requires adjuvant chemotherapy after surgery. Tumor stage II or above suggests postoperative chemotherapy and other treatments as adjuvant therapy, which can further improve the cure rate of surgery. Early invasive lung adenocarcinoma is recommended to go to professional hospitals and make appropriate treatment plan according to one’s condition under the guidance of doctors. In addition to the treatment measures in hospitals, it is also necessary to strengthen physical exercise, increase the intake of high-quality protein and pay attention to balanced nutrition.
