Mouth cancer is a type of head and throat cancer that most commonly affects people over the age of 40, with men being more at risk than women. It includes cancers of the lips, tongue, inner cheeks, gums, and the floor of the mouth. In many cases, oral cancer is only detected after it has spread to the lymph nodes in the neck, but if caught early, the chances of survival are much higher. Regular dental checkups—ideally twice a year—can help detect early signs before the condition becomes serious.
In its early stages, mouth cancer often shows no clear symptoms, which makes awareness especially important, particularly for people who smoke or consume alcohol regularly. As the disease progresses, symptoms may include non-healing sores in the mouth or lips, unexplained bleeding, loose teeth, difficulty swallowing, persistent mouth or ear pain, lumps in the neck, sudden weight loss, numbness in the face or lips, and red or white patches inside the mouth. While these symptoms do not always indicate cancer, they should not be ignored—especially if they persist or appear together—and medical or dental advice should be sought promptly.
The main causes of oral cancer include smoking, tobacco use in any form, and excessive alcohol consumption. The disease progresses through four stages: in Stage 1, the tumor is small and localized; in Stage 2, it grows larger but remains confined; in Stage 3, it may spread to nearby lymph nodes; and in Stage 4, it spreads to surrounding tissues or other parts of the body. Understanding these stages is important, as they determine treatment options and the likelihood of recovery, with early detection offering the best outcomes.
