There is no specific statistical data on the recurrence rate of mucinous lung cancer after stage II surgery, which is related to clinical stage, pathological type, therapeutic effect and patient’s condition, etc. It is recommended to carry out standardized treatment as early as possible. Mucinous lung cancer is also a type of lung cancer, and the treatment method is the same as that of common lung cancer. Early discovery of the disease allows surgical treatment, and after surgery, timely chemotherapy treatment according to the patient’s physical condition can kill the residual tumor cells after surgery, but there is a possibility of recurrence after surgery, and the earlier the surgical treatment is, the lower the recurrence rate is, the later the stage is, the higher the rate of recurrence after surgery is, but there is no specific data. However, there is no specific data. After stage II mucinous lung cancer surgery, it is recommended to go to the hospital in time to get a clear diagnosis and treatment, so as to avoid delaying the condition and leading to bad consequences.
