Tests for laryngeal cancer

You might have one or more of the following tests to diagnose and stage laryngeal cancer, or to check how well your treatment is working.

You usually start by seeing your GP if you have symptoms. They examine you and might refer you for tests.

Nasendoscopy for laryngeal cancer

A nasendoscopy is a test to look at the inside of the nose, throat (pharynx) and voice box (larynx).


You might have an endoscopy if your doctor couldn't see your larynx clearly using a nasendoscope, or if they saw an abnormal area. See what it is and how you have it.

Video of your throat and larynx (transnasal oesophagoscopy)

A transnasal oesophagoscopy is a test that uses a long, flexible telescope which is passed through your nose to make a video of the inside of your nose, throat, voice box (larynx) and upper part of the food pipe (oesophagus).

Video of your vocal cords (videostroboscopy)

A videostroboscopy uses a long, thin, flexible tube called an endoscope to examine your voice box (larynx) and vocal cords while you speak. 

Fine needle aspiration (FNA) for laryngeal cancer

A fine needle aspiration uses a thin needle to take a small sample of fluid and cells from a swollen lymph node in the neck.

Ultrasound for laryngeal cancer

Ultrasound scans use high frequency sound waves to create a picture of a part of the body.

CT scan for laryngeal cancer

A CT scan is a test that uses x-rays and a computer to create detailed pictures of the inside of the body.

MRI scan for laryngeal cancer

An MRI scan creates pictures using magnetism and radio waves. 

PET-CT scan for laryngeal cancer

A PET-CT scan combines a CT scan and a PET scan. It gives detailed information about your cancer.
