Where does carcinoma of the tongue commonly occur?

• A. Anterior dorsal surface
• B. Lateral border anteriorly
• C. Lateral border posteriorly
• D. Posterior dorsal surface

Answer: (C)

Carcinoma of the tongue commonly occurs on the lateral border posteriorly because this area is anatomically more susceptible to the carcinogenic effects of factors such as tobacco and alcohol use. The posterior lateral border of the tongue has a higher incidence of intraoral carcinomas, primarily due to the unique combination of the tissue type, increased exposure to potentially irritating substances, and the characteristic patterns of immune response in this region.

Additionally, tumors that develop in this area tend to have a more aggressive behavior, and their location can affect treatment options and prognosis. Understanding this anatomical and pathological context is crucial for both diagnosis and treatment planning in oral oncology. It can also help dental professionals recognize early signs of malignancy during routine examinations.
