What is buccal mucosa cancer?
Buccal mucosa cancer is a malignant tumor arising from the epithelial lining of the inner buccal mucosa and represents a major subtype of oral cancer. It typically presents as abnormal mucosal hyperplasia, ulceration, or a mass lesion, demonstrates local invasiveness, and may metastasize to cervical lymph nodes.
Main types and classification of buccal mucosa cancer
1.Squamous cell carcinoma
The most common type, accounting for more than 90% of cases; lower differentiation is associated with higher malignancy.
2.Minor salivary gland–derived carcinomas
Including adenoid cystic carcinoma and mucoepidermoid carcinoma, which have biological behaviors distinct from squamous cell carcinoma.
3.Other rare types
Such as verrucous carcinoma and malignant melanoma; although uncommon, they require differential diagnosis.
Etiology of buccal mucosa cancer
1.Tobacco and alcohol use
Smoking, chewing tobacco, and heavy alcohol consumption are major risk factors, with synergistic carcinogenic effects.
2.Betel nut chewing
A well-established independent risk factor, often combined with tobacco, and a key driver of high incidence in certain regions.
3.Human papillomavirus infection
Persistent infection with high-risk HPV types (e.g., HPV16) is associated with the development of some oral cancers.
4.Long-term local chronic irritation in the oral cavity
Sharp teeth, repeated friction from defective dental restorations, and poor oral hygiene can cause mucosal injury.
5.Nutritional factors and immune status
Vitamin deficiency and impaired immune function may increase risk.
Prevention and health maintenance for buccal mucosa cancer
1.Eliminate high-risk habits
Complete cessation of smoking and alcohol use and avoidance of betel nut chewing are the most effective primary prevention measures.
2.Maintain good oral hygiene
Brush properly, undergo regular dental cleaning, and promptly eliminate irritation from sharp teeth and defective restorations.
3.Maintain a healthy, balanced diet
Increase intake of fresh fruits and vegetables and avoid long-term consumption of excessively hot or spicy irritant foods.
4.Regular oral examinations and self-checks
Annual professional examinations are recommended. Be alert to persistent non-healing ulcers or new growths and seek medical attention early.
5.HPV vaccination
Vaccination against high-risk HPV types can be considered as a strategy to reduce the risk of HPV-associated cancers.
Conclusion
Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes that buccal mucosa cancer can cause facial disfigurement and functional impairment. Avoid tobacco and betel nut, and prioritize early detection and timely treatment. Comprehensive management centered on radical surgery can maximize tumor control, preserve organ function, and enable high-quality survival.
