Check the best method of fine Sputum examination chest, trachea, bronchi of the tomography, CT examination, bronchoscopy contrast, inflation mediastinal contrast, fiberoptic bronchoscopy.

Peripheral lung cancer: primary pulmonary peripheral, so very few have a cough, hemoptysis, and other symptoms, a small number of patients have chest pain, dull pain or intermittent pain, but when the tumor increased, and pleural invasion, when the chest wall, Have a position of sustained chest pain or irritation.
