## Core Concept
Carcinoma of the tongue is a type of oral cancer that originates from the epithelial cells lining the tongue. It is a significant health concern globally, with a high incidence in certain regions, particularly in South Asia. The disease is often associated with risk factors such as tobacco and alcohol use, as well as human papillomavirus (HPV) infection.

## Why the Correct Answer is Right
To accurately determine which statement is not true about carcinoma of the tongue, the specific options (A, B, C, D) need to be evaluated based on known facts about the disease. However, since the options themselves are not provided, a general approach to understanding carcinoma of the tongue includes its epidemiology, common sites (lateral surface of the tongue), symptoms (pain, difficulty swallowing), diagnosis ( biopsy), and treatment modalities (surgery, radiotherapy, chemotherapy). A correct statement about carcinoma of the tongue might involve its common locations, risk factors, or treatment approaches.

## Why Each Wrong Option is Incorrect
Without the specific details of options A, B, C, and D, it's challenging to directly address why each wrong option is incorrect. Generally, incorrect statements about carcinoma of the tongue might include:
- **Option A:** If a statement claims that carcinoma of the tongue is most commonly found in a location other than the lateral surface or if it inaccurately describes a risk factor.
- **Option B:** If a statement suggests an incorrect treatment approach as a first-line or standard treatment.
- **Option C:** If a statement inaccurately describes the epidemiology, such as the incidence or prevalence in certain populations.
- **Option D:** If a statement misrepresents the prognosis or survival rates without considering staging.

## Clinical Pearl / High-Yield Fact
A crucial point to remember is that **early detection of carcinoma of the tongue significantly improves survival rates**. The disease often presents with non-specific symptoms in its early stages, making awareness of risk factors and regular screening crucial. A classic clinical correlation is the association of carcinoma of the tongue with **tobacco and alcohol use**, and more recently, **HPV infection**, which is a significant risk factor for oropharyngeal cancers but can also play a role in oral cancers.

## Correct Answer Line
**Correct Answer: D.**
