Whether pulmonary infiltrating cancer can be cured or not needs to be judged comprehensively with the stage of disease, the degree of disease development and the patient’s physical condition. For patients with early stage lung infiltrating cancer without metastatic lesions, timely treatment by radical surgery, together with postoperative standardized comprehensive treatment, most patients have the possibility of cure. However, for patients whose disease has developed to middle or late stage, or whose lesions have metastasized to multiple tissues and organs, the possibility of cure is lower at this time. Patients with early stage of lung invasive cancer, especially those with small lesions, such as those without metastasis within 2 cm, can generally be cured by surgery. It should be noted that if the postoperative period is longer than 5 years, dynamic review of high-resolution CT of the chest is needed to understand whether the lesion shows any recurrence. If the lung invasive cancer is in the middle and late stage, the lesion is easy to metastasize and can infiltrate and metastasize to other organs, and the recurrence rate is higher and the cure rate is relatively lower. At this time, it can be treated by surgical resection and postoperative adjuvant radiotherapy and chemotherapy, or apply palliative treatment and immunotherapy to slow down the development of the disease and improve the quality of survival. Therefore, early detection, early diagnosis and early treatment are of great significance for the prognosis of the disease. In daily life, pay attention to regular review, adjust diet, eat more high-protein diet and fresh vegetables and fruits, reduce exposure to cigarettes, exhaust fumes and other irritating odors, keep indoor ventilation, and exercise appropriately to enhance physical fitness and promote disease recovery.
