Diagnosis of roentgenographically occult lung cancer by sputum cytology

Clin Chest Med. 2002 Mar;23(1):59-64. doi: 10.1016/s0272-5231(03)00060-1.


The specialty has the knowledge and technology to change the outcome of lung cancer. Lung cancer, diagnosed in early stages, is as curable as all other cancers. Sputum cytology is the initial step in diagnosing roentgenographically occult lung cancer. Sputum cytology is complementary to CT scanning. Sputum cytology identifies small central lesions, and CT scanning discovers peripheral tiny adenocarcinomas.
