What causes oral cancer and how can we prevent it?
We know that excessive consumption of alcohol is detrimental to oral health, but why? We know that tobacco smoking, alcohol, and poor oral hygiene cause increased acetaldehyde levels in saliva. Alcohol itself is not carcinogenic, but it is metabolised to acetaldehyde which has been strongly implicated in the development of oral cancer. The variation between people in how they metabolize alcohol might explain why some are at greater risk of cancer than others.
