Bronchoscopy is a medical procedure that allows doctors to examine the airways and lungs. During the procedure, a thin, flexible tube called a bronchoscope is inserted through the nose or mouth and into the lungs. This tool is equipped with a light and camera, enabling doctors to visualize the inside of the airways and identify any abnormalities, such as infections or tumors. In addition to diagnosis, bronchoscopy can also be used for treatment purposes. Doctors can remove mucus, foreign objects, or tissue samples for further testing. This procedure is typically performed in a hospital or specialized clinic and may require sedation for patient comfort.
