Quick answer
What is Mouth cancer?
Mouth (oral) cancer can develop anywhere in the mouth, including the lips, tongue, gums, and the lining of the cheeks and floor of the mouth. Common warning signs include a mouth ulcer or sore that does not heal within three weeks, a persistent red or white patch, an unexplained lump or thickening, a persistent sore throat or hoarse voice, difficulty or pain swallowing, or a loose tooth or ill-fitting denture without a dental cause.
- How it is treated: Treatment depends on the site, size and stage, and the person's health, and is planned by a specialist head and neck cancer team.
- Self-care: Not smoking or using tobacco, keeping alcohol within limits, eating plenty of fruit and vegetables, protecting lips from sun, and having regular dental check-ups (which include checking the mouth) all reduce risk and aid early detection.
- When to seek help: See a dentist or GP about a mouth ulcer or sore lasting more than three weeks, a persistent red or white patch, an unexplained lump, or ongoing difficulty swallowing or hoarseness.
What it is
Mouth (oral) cancer can develop anywhere in the mouth, including the lips, tongue, gums, and the lining of the cheeks and floor of the mouth. Common warning signs include a mouth ulcer or sore that does not heal within three weeks, a persistent red or white patch, an unexplained lump or thickening, a persistent sore throat or hoarse voice, difficulty or pain swallowing, or a loose tooth or ill-fitting denture without a dental cause. The main risk factors are smoking and other tobacco use, heavy alcohol (especially combined with smoking), and infection with certain types of HPV. Because outcomes are much better when it is caught early, persistent changes should be checked promptly by a dentist or doctor.
How it is treated
Treatment depends on the site, size and stage, and the person's health, and is planned by a specialist head and neck cancer team. Options include surgery to remove the cancer, radiotherapy and chemotherapy, used alone or in combination; newer targeted and immunotherapy treatments are used in some cases. Because the mouth is vital for eating, speaking and appearance, care includes support to preserve or restore function, with input from dietitians, speech and language therapists and dental teams. Stopping smoking and reducing alcohol improve outcomes. Regular dental check-ups help detect changes early, and are an important opportunity for screening.
