Lung or bronchial biopsy (tissue samples taken to diagnose or rule out disease) may be done with the use of a flexible bronchoscope, an instrument with a small light and camera which is inserted through the nose or mouth. When a suspicious area is seen, an instrument is channeled through the bronchoscope to take a sample for analysis.
