Generally speaking, according to the condition of the patient, he/she should go to the corresponding department, such as thoracic surgery, respiratory medicine, oncology, etc. The purpose of review after lung cancer surgery is to check the recovery from surgery. 1. Thoracic Surgery: the purpose of review is to check the recovery from surgery, and it is necessary to go to Thoracic Surgery of the original surgery department, because the original department knows more about the patient’s past medical history and surgery, so that it can better evaluate the recovery from surgery and give the next step of treatment. 2. Respiratory medicine: If the patient has recovered well after surgery, but has lung infection for some reason, and needs to be treated for the lung infection, he/she can usually consult the respiratory medicine department. 3. Oncology: because lung cancer sometimes needs comprehensive treatment, such as radiotherapy, chemotherapy, etc., oncology can be registered. If you don’t know what department to consult after lung cancer surgery, you can first consult the original surgery department, and then listen to the doctor’s opinion and consult the corresponding department, or go to the consulting desk of the hospital to consult the doctor.
