Bronchoscopy is performed primarily for two purposes. The first one is diagnostic bronchoscopy and the second one is therapeutic bronchoscopy. Sometimes, during the bronchoscopy performed for diagnostic purposes, small treatment procedures can be performed, or sometimes diagnostic samples may be taken during bronchoscopy.

Bronchoscopy is performed in the presence of respiratory symptoms such as chronic cough, bloody sputum, hoarseness, which cannot be explained by other diagnostic methods.
