Mouth Cancer: What You Need to Know
Mouth cancer, also called oral cancer, is one of the most common types of head and neck cancers, yet it often goes unnoticed until it reaches an advanced stage. It usually affects people over 40, with men at higher risk than women. In India alone, more than 77,000 new cases are diagnosed each year, resulting in over 52,000 deaths.
These numbers highlight the critical need for awareness, early detection, and timely treatment. Where Mouth Cancer Can Develop
Oral cancer can appear in different areas of the mouth, including:
Lip cancer – affecting the inner or outer lips. Tongue cancer – often starting on the sides or underside of the tongue.
Inner cheek cancer – forming inside the cheek lining. Gum cancer – appearing around the teeth. Floor of mouth cancer – affecting the area beneath the tongue.
Because oral cancers are often painless in their early stages, they can go unnoticed for months. Dentists recommend that individuals, especially smokers and heavy drinkers, have their mouths checked at least twice a year. Early detection greatly improves treatment success and survival.
A sore or blister in the mouth or on the lips that doesn’t heal. Unexplained bleeding in the mouth. Persistent mouth pain or difficulty swallowing.
A lump in the neck or sudden jaw swelling. Loose teeth without clear reason. Ear pain on one side without infection.
Sudden, unexplained weight loss. Numbness in the lips, chin, or face. Red or white patches inside the mouth or on the lips.
Dry mouth that doesn’t improve with hydration. Stiffness or pain in the jaw. Constant sore throat or tongue pain.
While these symptoms don’t always indicate cancer, ignoring them can be dangerous. If they persist for more than two weeks or occur together, seek medical attention immediately. Main Causes of Mouth Cancer
Most oral cancer cases are linked to lifestyle choices.
Around 80% of cases are associated with tobacco use. Key risk factors include:
Smoking – cigarettes, cigars, and pipes. Chewing tobacco – gutkha, betel quid, snuff, or other smokeless forms.
HPV infection – certain strains of human papillomavirus are linked to oral cancer. Poor oral hygiene – chronic irritation from neglecting oral health. Stages of Mouth Cancer
Cancer staging helps determine disease progression and appropriate treatment:
Stage 1: Tumor is under 1 inch, not spread to lymph nodes.
