The course of disease is longer, blood in sputum is rare, and the change of erythrocyte sedimentation rate is less. Tuberculosis is found in 16% - 28% of patients' sputum.

Sometimes it is difficult to differentiate bronchopneumonia in elderly patients with pulmonary inflammation from obstructive pneumonia caused by bronchial obstruction of lung cancer. Obstructive pneumonia usually has fan-shaped distribution according to bronchial branches, while general bronchopneumonia has irregular patchy shadow.

Benign tumor of lung and bronchial adenoma, benign tumor of lung such as structural tumor, chondroma, fibroma are rare, but they must be differentiated from peripheral lung cancer. Generally, the course of benign tumor is long, the growth is slow, and most of them have no clinical symptoms. On X-ray film, they are usually round block shadow, with neat edge, no burr, and no lobulation.
