Bronchoscopy is a procedure to look inside the trachea and large airways in the lung for abnormal areas. A bronchoscope is inserted through the nose or mouth into the trachea and lungs. A bronchoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue samples, which are checked under a microscope for signs of cancer.

A bronchoscopy is a procedure during which an examiner, usually a pulmonologist or thoracic surgeon, uses a viewing tube to evaluate a patient's lung and airways, including the voice box and vocal cord, trachea, and bronchial branches. Although a bronchoscope does not allow for direct viewing and inspection of the lung tissue itself, samples of the lung tissue can be biopsied through the bronchoscope for subsequent examination in the laboratory.

Bronchoscopy is a diagnostic procedure used to obtain a small amount of lung tissue and fluid samples, which are then examined under a microscope to help in diagnosing a change in your lung function. During this procedure, your lung doctor examines your lungs (bronchial tubes) and looks for abnormal conditions, such as infection, tumors, bleeding and abnormal sites.
