Oral cancer can arise in several parts of the mouth, including the lips, tongue, cheeks, gums, floor of the mouth, and palate. In India, the burden is particularly high. Each year, more than 77,000 new cases are reported, and over 52,000 people lose their lives to this disease. It remains one of the top cancer-related causes of death in the country.
One of the main reasons for this high mortality is delayed detection. Many cases are discovered only after the cancer has spread to nearby tissues or lymph nodes. With early diagnosis, however, the chances of successful treatment increase significantly.
Awareness and regular screening are essential.
Types of Oral Can:cer
Oral can:cer can affect any of the following areas:
- Lips
- Tongue
- Gums
- Inner cheek (buccal mucosa)
- Floor of the mouth
- Hard and soft palate
Although symptoms may differ slightly depending on the location, all forms require prompt medical evaluation.
Common Symptoms of Oral Can:cer
Early-stage oral cancer may not cause noticeable discomfort, making self-monitoring especially important for individuals in high-risk groups. Watch for:
- Non-healing mouth sores
- Red, white, or mixed-color patches
- Lumps, swelling, or thickened tissue inside the mouth or neck
- Unexplained bleeding
- Loose teeth without obvious dental cause
- Pain or difficulty chewing and swallowing
- Numbness of the lips, tongue, chin, or neck
- Persistent sore throat or hoarseness
- Jaw stiffness or pain
- Ear pain unrelated to hearing problems
- Chronic dry mouth or burning sensations
- Unintentional weight loss
Causes and Risk Factors
Several factors can increase your likelihood of developing oral cancer:
- Tobacco use in any form. Nearly 80 percent of oral cancer cases are linked to tobacco.
- Heavy alcohol consumption, especially when combined with tobacco.
- HPV infection, which is increasingly associated with cancers in the throat and base of the tongue.
- Poor oral hygiene, which allows chronic irritation and infections to persist.
- Excessive sun exposure, a major risk for lip cancer.
- Family history of cancer.
- Nutritional deficiencies, particularly low fruit and vegetable intake.
Stages of Oral Cancer
Cancer staging helps determine treatment and prognosis:
-
Stage 1: Tumor under 2 cm; no lymph node involvement.
-
Stage 2: Tumor 2–4 cm; still no lymph node spread.
