Bronchoscopy
 
 

A bronchoscopy uses a tube-like scope to look at air passages and lungs. The scope goes into the lungs after being passed through the nose or mouth and trachea. A bronchoscopy is done to check the lungs or take a lung tissue sample. It can detect growths, cancers, lung disease, infections, foreign objects, inhaled chemicals or toxins. A bronchoscopy may be performed if an individual has a persistent cough and the reason for the cough is undetermined.
