Lung tumor screening hangs on respiratory medicine, thoracic surgery, and medical oncology. Lung tumors include benign and malignant tumors, which are tumors that occur in human lung tissues. When the patient has blood in the sputum, nodules in the lungs and so on, it is necessary to consult the doctor in time. Lung tumors can be examined by the department of respiratory medicine, such as lung enhancement CT, tumor markers, etc. If necessary, percutaneous lung puncture biopsy and other pathological examinations can be carried out to clarify the nature of the tumor. If the patient is diagnosed with lung tumor and has surgical indication, he can hang up with thoracic surgery department and undergo examination and treatment in thoracic surgery department. If the tumor has progressed to an advanced stage and cannot be operated, the patient can register with the Department of Medical Oncology and be actively treated with chemotherapy, radiotherapy, immunotherapy, targeted therapy and other treatments. You can consult your doctor in advance for lung tumor screening and make good preparations before the examination so as not to affect the examination results.
