A bronchoscopy helps to diagnose lung disease. Your doctor may order a bronchoscopy to view your throat and airways. A bronchoscopy can help your doctor diagnose lung problems, such as a growth or tumor.

What is a bronchoscopy?

With a bronchoscopy, your doctor uses a small camera to see inside your lungs to look at the airways anatomy and how well they are working. A scope (thin tube) is passed through your mouth or nose and into your windpipe. This lets your doctor view your airways and take a biopsy of lung tissue of suspicious areas if necessary. A bronchoscopy also may be used to treat a lung problem, such as removing fluid buildup, treating cancer, washing out an airway.

Who needs a bronchoscopy?

There are a number of reasons that a provider may refer you for a bronchoscopy.

  • Long-lasting cough
