If larynx cancer is suspected, the doctor will examine swelling or lumps in the neck. An angled mirror that faces downwards is placed against the back of the throat (the palate) to examine the voice box and surrounding organs. Alternatively, a flexible tube, less than a centimetre in diameter, is passed into one of the nostrils to the back of the throat to look for lumps or ulcers in the voice box and surrounding areas.
