The bronchoscope is a thin, flexible tube passed through your mouth or nose, down the trachea, through the bronchi into the lungs, and into the smaller branches of the airway, the bronchioles. A bronchoscopy allows your physician to evaluate the condition of your airway and lungs, take tissue samples and perform treatments, including:

• Suction out secretions or blood
• Remove foreign objects
• Control bleeding
• Remove lesions
• Place stents
• Inject medicine into the lungs
