Bronchoscopy along with biopsy is a slight intrusive procedure that allows for direct sight of the airways and collection of tissues from the lungs and bronchi. This process is important in diagnosing various types of pulmonary diseases, like infections, inflammatory processes, or tumors. The bronchoscope, which is made up of a thin flexible tube containing light source and at times a camera, passes through respiratory tract directing the instruments used for biopsy to their respective sites.

It is used for diagnosis of respiratory diseases in cases in which the parson is suffering from consistent coughing or coughing up blood. Also, in cases when the results from other diagnostic procedures such as computerized axial tomography scanning or X-ray examination have showed abnormal findings in chest, the bronchoscopy is used for further examination. Bronchoscopy is also used for removal for foreign objects from airways.

Biopsy of the lung through bronchoscopy is a major contribution in diagnosing and handling pulmonary disorders. The device allows doctors to visualize selected tissues directly, which makes it an invaluable instrument in respiratory medicine. If performed correctly and with patient care, lung biopsy can result to precise diagnosis as well as better outcomes for the patient.
