Trachea Tests. 1  Flexible bronchoscopy: An endoscope (flexible tube with a lighted camera on its end) is passed through the nose or mouth into the trachea. 2  Using bronchoscopy, a doctor can examine the trachea and its branches. 3  Rigid bronchoscopy: A rigid metal tube is introduced through the mouth into the trachea. A procedure called bronchoscopy is usually needed to remove a foreign body from the trachea. 2  Tracheal cancer: Cancer of the trachea is quite rare. 3  Symptoms can include coughing or difficulty breathing. 4  Tracheomalacia: The trachea is soft and floppy rather than rigid, usually due to a birth defect.
