According to the data, the recurrence rate of early invasive lung cancer is generally less than 10%. The recurrence rate of early invasive lung cancer is not high, and early invasive lung cancer is only a generalized concept. It can be divided into stage Ⅰ and stage Ⅱ, and stage Ⅰ is divided into stage Ⅰa and stage Ⅰb. According to the size of the tumor and whether the lymph nodes are metastatic or not, the more detailed the pathological stage is divided into, the accuracy of the recurrence rate will be improved and may reach a certain percentage. For example, the cure rate of patients with stage Ia can reach 95% to 97% with current surgical treatment, while the recurrence rate is around 1% to 2%. The recurrence rate of early-stage invasive lung cancer is usually less than 10%, and the recurrence rate may slightly increase after surgery if radical surgical treatment is not performed. Therefore, after the surgery, patients should go to the hospital for regular checkups, such as chest CT and chest radiographs, to find out whether there is any possibility of recurrence. If you find any discomfort after treatment, you should consult a doctor in time to determine your condition and the possibility of recurrence under the doctor’s professional diagnosis, and actively cooperate with the doctor’s treatment.
