Early stage lung cancer is usually recoverable. Early stage lung cancer can be cured after complete removal of the lesion and standardized treatment. The current common surgical methods for early stage lung cancer are open thoracic direct vision surgery and thoracoscopic surgery. Thoracoscopic surgery can accurately remove the patient’s lesions and make the patient recover. Generally, there is no need to do radiotherapy or targeted therapy after surgery for early stage lung cancer, and most of the patients will not have recurrence but need regular review and follow-up. Early detection of lung cancer and standardized treatment can achieve better curative effect. Early stage lung cancer treatment is mainly based on surgical treatment. For some patients who cannot be treated surgically, radiotherapy or targeted drug therapy such as gefitinib and erlotinib can be used in localized foci to enable patients to survive for a long time. The most typical symptom of early stage lung cancer is persistent dull pain at a fixed point on one side of the chest. When symptoms of chest pain appear, consult a doctor in time to clarify the condition and carry out standardized treatment under the guidance of doctors.
