What is tongue cancer?
Tongue cancer is a malignant tumor arising from the epithelial tissue of the tongue and has the highest incidence among oral cancers. It most commonly occurs on the lateral border and ventral surface of the tongue, and the predominant histologic type is squamous cell carcinoma. The disease is characterized by strong local invasiveness and a propensity for early lymph node metastasis. Clinical manifestations include tongue pain, ulceration, and impairment of tongue mobility.
Main types and classification of tongue cancer
1.Squamous cell carcinoma
Accounts for more than 90% of cases. Lower differentiation is associated with higher malignancy and a greater likelihood of early lymph node metastasis.
2.Other rare types
Including adenoid cystic carcinoma and mucoepidermoid carcinoma, which have biological behaviors distinct from squamous cell carcinoma.
3.Molecular subtyping
Based on HPV status and genomic alterations; HPV-positive tumors generally have a better prognosis than HPV-negative tumors.
Etiology of tongue cancer
1.Tobacco and alcohol
Smoking, smokeless tobacco use, and heavy alcohol consumption are major risk factors, with synergistic carcinogenic effects.
2.HPV infection
HPV16 may contribute to carcinogenesis through E6/E7-mediated disruption of the cell cycle and is closely associated with tongue cancer.
3.Genetic factors
Hereditary syndromes such as Fanconi anemia and familial aggregation increase susceptibility.
4.Local oral factors
Chronic trauma from defective dental restorations or sharp teeth, as well as poor oral hygiene.
5.Other factors
Immunosuppression, deficiencies of vitamins A/C/E, and long-term betel nut chewing.
Prevention and health maintenance for tongue cancer
1.Avoid risk factors
Quit smoking, limit alcohol intake, avoid betel nut, and eliminate chronic mucosal irritation.
2.Oral hygiene and health care
Maintain good oral hygiene, undergo regular dental examinations, and address factors causing chronic injury.
3.HPV prevention
HPV vaccination and safer sexual practices to reduce infection risk.
4.Healthy diet
Increase consumption of fruits and vegetables, supplement vitamins, and avoid overly hot or spicy foods.
5.Self-examination and screening
Perform regular self-examination of the tongue, and high-risk individuals should undergo professional screening.
6.Functional rehabilitation
Actively participate in postoperative speech and swallowing training to improve quality of life.
Conclusion
Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes that tongue cancer is highly invasive and prone to metastasis. Multimodal management centered on surgery, with an emphasis on functional preservation, is essential. Strengthening health education, avoiding risk factors, promoting early screening, and applying an MDT-based approach can substantially improve prognosis and quality of survival.
