The cure rate of stage I lung adenocarcinoma after surgery is high, while the location of the lesion adjacent to the large airway and the cleanliness of the surgical margin will also determine the cure rate of stage I lung adenocarcinoma after surgery to some extent. If the follow-up and care are good, the 5-year survival rate can reach about 90%, but the specific cure rate has a fluctuating value, which varies from person to person and cannot be generalized. Lung cancer is divided into various pathological types, including adenocarcinoma of the lung, squamous lung cancer, small cell lung cancer, etc. The clinical symptoms of stage I lung adenocarcinoma are less common, and it is less common to find out stage I lung adenocarcinoma by yourself. Stage I lung adenocarcinoma is usually staged according to the size of the tumor and the presence of lymph node metastasis. Stage I lung adenocarcinoma usually does not have lymph node metastasis or distant metastasis, but only primary tumor foci, and the primary foci are usually small. If radical surgery can be performed in time to remove the lesion, the cure rate is generally higher and the prognosis is better, and the 5-year survival rate can reach about 90%. Therefore, it is recommended that people over 40 years old should have an imaging examination such as lung CT or X-ray once a year to rank whether lung lesions have occurred, which will enable most lung adenocarcinoma patients to detect the disease at an early stage and receive timely treatment. After surgery for stage I lung adenocarcinoma patients, regular follow-up examinations are recommended to observe changes in the disease. If you feel unwell, you should also go to the hospital for timely consultation. In daily life, patients are advised to quit smoking and alcohol, and can exercise appropriately to enhance their physical fitness.
