After the patient starts to cough in the morning, the first and second sputum will be spit out. After spitting from the deep part, the patient should be sent to the laboratory within half an hour, and the sputum with blood sputum should be selected for examination. Generally, 4-6 sputum tests are appropriate.

Bronchoscopy is an effective method for the diagnosis of lung cancer. Through bronchoscopy, we can observe the location and scope of the tumor, take the tissue for pathological examination, and speculate the possibility of surgical resection according to the activity of vocal cord, the compression of trachea and the activity of carina.

Because the cross-sectional anatomy showed by the examination does not overlap, has a high density resolution, and can check the lung and mediastinum at the same time, it is the most valuable for preoperative detection of pulmonary lymph nodes, and can understand the location of enlarged lymph nodes, especially N1, N2, etc., which is conducive to the choice of treatment, and helps to determine the surgical operation and scope. CT can accurately distinguish different soft tissues (tumor, mediastinum, pleura) by different window width and window level, and quantitatively measure CT value.
