Early invasive lung adenocarcinoma may recur. Early infiltrative lung adenocarcinoma refers to the tumor volume is less than 3cm, and there is no metastasis and proliferation of lymph nodes and distal organs, after radical surgery, most patients can be cured, but some of the patients belong to the type of higher degree of malignancy, so there is a possibility of recurrence in the later stage. In addition, surgery can only remove the tumor tissue that can be seen by the naked eye, and if metastasis and proliferation have already occurred at the time of surgery, recurrence will occur. Therefore, for patients with high risk of recurrence and metastasis, they need to undergo targeted postoperative radiotherapy and chemotherapy treatments. It is recommended that patients strictly follow the doctor’s instructions for regular review in order to detect recurrence and metastasis at an early stage and treat them at an early stage.
