It is possible that the life expectancy after surgery for early stage lung cancer is the same as that of normal people, but the specific situation varies from person to person. Early stage lung cancer usually has no metastasis and can be cured by timely surgery to remove the primary lesion and metastatic lymph nodes, which does not affect the life expectancy and therefore may be the same as normal people. However, due to individual differences, the specific survival time also varies from person to person, which is generally related to the later care and one’s psychological state. Lung cancer is a common malignant tumor with high morbidity and mortality. The causes of the disease are mainly related to smoking, exposure to toxic and harmful substances in occupational environment, history of previous lung infections and heredity, and the common symptoms include cough, sputum, low-grade fever, chest pain and asthma. Therefore, it is important to avoid exposure to toxic environments, quit smoking as much as possible, and consume more fresh fruits and vegetables. It is suggested that once diagnosed with early stage lung cancer, it should be treated in time, and usually pay attention to relaxing the mind, which can help to improve the survival period.
