The majority - around 90% - of cancers to lip, mouth and oropharynx are squamous cell cancers. Rarer types of cancer affecting the mouth contain salivary gland carcinoma, lymphoma and melanoma. These unusual types are not covered by this guidance.
This sort of cancer is rare in people under 50 and is more common in men. There are several well recognized risk factors including smoking, drinking, and chewing tobacco or betel nut. The risks are higher intended for someone who both smokes and drinks. Mouth cancer has started to affect younger people who do not smoke or drink terribly – these mouth cancers are thought to be linked with Human Papilloma Virus (HPV) infection.

Mouth cancer has started to affect younger people who do not smoke or drink terribly – these mouth cancers are thought to be linked with Human Papilloma Virus (HPV) infection.These cancers are more common in people who are immune suppressed either because they are taking immunosuppressant drugs or since they have AIDS. There are two conditions of the mouth that are precancerous and they are called leukoplakia and erythroplakia. They are not cancer of the mouth in themselves, but can extend into cancer if not treated. Life long treatment and follow up is essential.
5,300 people develop lip, mouth and oropharyngeal cancer every one year in the UK. The five year survival is just over 50%. Results for people with lip cancer are much better at around 90%; this is because changes in the lip are noticed early compared to changes within the mouth.
