A thin tube with a light and camera on the end (laryngoscope) is passed down your throat. This test allows the doctor to examine the larynx.

You will have this done if the doctor sees anything unusual in your throat, or cannot see the larynx clearly with the nasendoscope.

You need to have a general anaesthetic for the test. This allows the doctor to examine the larynx using a laryngoscope. A laryngoscope is a thin, metal tube with a light on the end. The doctor passes the laryngoscope down your throat, to look at the larynx closely. They may also take photos using a camera that is attached to the tube.

During the laryngoscopy, the doctor takes a small sample of cells or tissue (biopsy) from any abnormal looking areas. This is the most important test to diagnose laryngeal cancer.

A doctor called a pathologist will examine the sample under a microscope and check for cancer cells. It may take about 7 to 10 days for your results to come back.
