It is not possible to determine how long a patient can live after lung tumor removal, but can only be observed while treatment. After lung tumor resection, it should be considered that the treatment effect is good and the patient may be able to survive for a long time, but it also depends on the subsequent development of the disease and the pathological nature of the lung tumor. If it is a benign lung tumor, as long as the patient recovers well after resection, it will not affect the survival period and can be cured. If it is a malignant lung tumor, it also depends on the stage. Early stage lung malignant tumor can be cured by surgical resection. Some patients with carcinoma in situ can have a 10-year survival rate of more than 95%, and can also survive for a long time without affecting their survival period. If it is some lung malignant tumor with less early stage, after resection, patients still need to cooperate with radiotherapy, chemotherapy and other comprehensive treatment, and observe while treatment. If there is no recurrence for more than 5 years, it is considered as clinical cure.
