Is one of the most common human lung organ problems, the most common is inflammation, then tuberculosis and tumor diagnosis, tumor in clinic is a difficult problem, so we introduce some main points of diagnosis of lung cancer.
1, lung benign tumor
Benign lung tumors are sometimes associated with peripheral lung cancer. Benign lung tumors generally do not show clinical symptoms, slow growth, long course of disease. Show nearly circular mass in the X-ray films, may have calcification, the outline of neat, clear boundary, no lobulated.
2, solitary metastatic lung cancer

The differential diagnosis mainly depends on the detailed history and primary tumor symptoms and signs. Metastatic lung cancer is generally less respiratory symptoms and sputum, sputum cytology is not easy to find cancer cells.
3, mediastinal tumor
Central type lung cancer may sometimes be confused with mediastinal tumors. The diagnosis of artificial pneumothorax is helpful to define the location of the tumor. Mediastinal tumors were less likely to be detected by sputum cytology. Often bilateral lesions, fever and other systemic symptoms can be. One
