Bronchoscopy

Bronchoscopy is a procedure doctors use to look at the airways leading to the lungs. During bronchoscopy, a thin, lighted instrument (bronchoscope) is inserted through the nose or mouth into the throat and then into the airways leading to the lungs.

Bronchoscopy can be used to collect samples of tissue or sputum for analysis, to check for growths (such as tumors) in the airways, and to remove blockages in the airways.
