Cancer of the mouth (also known as cancer of the lip and oral cavity) is a malignant tumor that affects the lips, mouth structures such as the gums, cheeks, roof of the mouth, tongue (especially the edges) and the area under the tongue. It is more common in men over 40 years of age, being the fourth most frequent tumor in males in the Southeast region. Most cases are diagnosed in advanced stages.
The back of the tongue, the tonsils and the fibrous palate are part of the region called oropharynx and their tumors behave differently from cancer of the oral cavity.
