Patients with early stage lung cancer who are still in good health and do not have too many underlying diseases are definitely better off having surgery, and simple conservative treatment is not as good as surgery. Specifically, for patients who are suitable for surgery in stage I, anatomical lobectomy and mediastinal lymph node dissection, or thoracoscopic surgery are recommended. For patients with stage II lung cancer and stage IIIA or IIIB, surgery can be performed directly or after neoadjuvant radiotherapy. There is a lot of clinical evidence that surgery in patients who are suitable for surgery has a much longer survival than without surgery. Make a rational choice after communicating with the professional thoracic surgery team at the hospital, and do not feel as if the patient is afraid to undergo a relatively large surgery and miss the best time for treatment.
