Experts have warned to look out for a 'persistent' ear symptom that could be a sign of a much bigger issue.
In the UK alone, there are more than 2,000 new cases of laryngeal (larynx) cancer - which starts in the voice box. The disease, which is more common in those over the age of 60, can result in extreme surgery that leaves sufferers with a permanent hole in their neck (medically known as a stoma).
Smoking, regularly drinking large amounts of alcohol, and having an unhealthy diet low in fruit and veg can increase your risk of larynx cancer - but the exact cause isn't clear. As with any type of cancer, an early diagnosis is essential in increasing the chances of survival.
So, here's everything you should look out for, and when to contact your GP.

Arnold’s nerve gives sensation to the ear itself, so when you have something causing pain in your throat, the referred pain is felt in your ear."
