**3. The place of conflict**

The most common site of oral cancer is the lip. Lip cancer often occurs in lightskinned older men and most often affects the lower lip. Risk factors for lip cancer include sun exposure, certain occupations such as agriculture, socioeconomic status, smoking and pipe. Inside the mouth, the high-risk sites for cancer are the abdominal surface, the posterior sides of the tongue, the floor of the mouth, and the soft palate. Tongue cancer is the most common malignancy in the mouth. Tongue cancer is more common in men in their sixth and seventh decades of life. Tongue lesions are often aggressive. The second most common intraoral site for cancerous changes is the floor of the mouth. Tumors in this area occur in older men, especially in smokers and alcoholics. Involvement of the cheeks and gums is also common, especially in areas where there are certain habits such as chewing tobacco [8].
