A bronchoscopy is a test to examine the parts of the body that allow you to breathe.
The doctor uses a thin, flexible telescopic instrument called a bronchoscope. It is passed through the nose or mouth and down into the airways. It allows your doctor to:
- see your windpipe (trachea) and airways (bronchi)
- look for anything unusual
- take photographs
- take samples of lung tissue (biopsies) or of secretions, which can then be examined under a microscope.
