The general description of early stage lung cancer also needs to be evaluated according to pathological staging, and the 5-year survival rate is about 80% or more. Lung cancer is a malignant tumor belonging to the respiratory system. After early lung cancer is detected in time and given surgical resection, more than 80% of the patients have a survival period of more than 5 years, and even a considerable portion of the patients have a survival time of more than 10 years, and if there is no recurrence after more than 10 years, the survival period may continue to be prolonged, and the chances of recurrence will be significantly reduced. For patients with lung malignant tumors, lung adenocarcinoma and lung squamous carcinoma are relatively common. Early radical treatment through surgery can achieve obvious therapeutic effect without radiotherapy or radiotherapy after treatment, and a part of lung adenocarcinoma patients with mutations in gene test can undergo targeted therapy. For patients with early lung cancer, it is recommended to consult the thoracic surgery department of regular hospitals for surgical treatment. After surgery, patients should undergo regular checkups to prevent recurrence.
