Lung cancer is the most common primary malignant tumor of the lung. The vast majority of lung cancer originates from bronchial mucosal epithelium, so it is also called bronchial lung cancer. In the diagnosis of lung cancer, fiberoptic bronchoscopy is essential. Because lung cancer is a bronchial tumor, especially those early tumors are difficult to find by X-ray or CT film only. At this time, bronchoscopy, which can directly observe the trachea, has become a very effective method. At present, a large number of lung cancer patients are diagnosed by bronchoscopy biopsy or cytology.

How to do lung cancer bronchoscopy biopsy? Fiberoptic bronchoscopy can be performed under local anesthesia, easy to operate, and less painful for patients. Visible range reaches the main bronchus, leaf bronchus, segment bronchi and secondary bronchi. You can also take tissues for the pathological examination of the lesions you see, or you can use small brushes to brush the cells in the lesions for cytological examination. To achieve a clear diagnosis. After observation through bronchoscopy, the doctor can stage lung cancer according to the extent and severity of the lesion to guide the selection of appropriate treatment options.
　　Bronchoscopy can not only diagnose lung cancer, but also has a very wide range of uses in treatment. For some intratracheal tumors, bronchoscopy tumor resection can also be performed to avoid the pain of surgery. In addition, for lung cancer patients who are not suitable for surgery, cryotherapy, injection of chemotherapy drugs, photodynamic therapy, internal stent placement, intraluminal radiotherapy, etc. can be performed under bronchoscopy.
