Early stage lung adenocarcinoma has a chance to be cured. The tumor volume of early stage lung adenocarcinoma patients is mostly within 3cm, and there is no metastasis or spreading of local lymph nodes and distal tissues, so most of the patients can be cured after timely radical surgery to remove the tumor tissues or expand the resection. Some patients are at high risk of recurrence and metastasis, and can be treated with radiotherapy and chemotherapy according to the results of the pathological examination, and the chances of recovery are also relatively high. Only a very small number of patients with malignant early lung adenocarcinoma have metastasis and proliferation at early stage and miss the best time for treatment, which leads to increased difficulty in treatment. It is suggested that patients should consult the doctor in time and treat actively to avoid delaying their condition.
