Here’s a clear, reliable overview of Mouth (Oral) Cancer — written so it’s easy to recognize warning signs early and understand what to do next.
🩺 What Is Mouth Cancer?
Mouth cancer (oral cancer) affects the lips, tongue, gums, inner cheeks, floor of the mouth, hard/soft palate, and sometimes the throat.
Most cases are squamous cell carcinomas.
⚠️ Early Symptoms (Most Important)
See a doctor or dentist if any of these last longer than 2 weeks:
-
Mouth sore or ulcer that doesn’t heal
-
Red or white patches inside the mouth
-
Lump, thickened area, or rough spot
-
Pain, numbness, or burning in the mouth
-
Difficulty chewing, swallowing, or speaking
-
Loose teeth or ill-fitting dentures
-
Persistent sore throat or hoarseness
-
Jaw stiffness or swelling
-
Unexplained bleeding in the mouth
🚨 Early mouth cancer is often painless — don’t wait for pain.
🎯 Causes & Risk Factors
Major causes include:
-
Tobacco use (smoking, chewing, vaping)
-
Heavy alcohol use
-
HPV infection (especially HPV-16)
-
Excessive sun exposure (lip cancer)
-
Poor oral hygiene
-
Weakened immune system
-
Age over 40 (but rising in younger adults due to HPV)
➡️ Tobacco + alcohol together increase risk dramatically.
🧬 Stages of Mouth Cancer
Staging depends on tumor size and spread:
-
Stage 0: Abnormal cells only (carcinoma in situ)
-
Stage I: Tumor ≤ 2 cm, no spread
-
Stage II: Tumor 2–4 cm
-
Stage III: Larger tumor or spread to one lymph node
-
Stage IV: Spread to multiple lymph nodes or distant organs
📌 Earlier stage = much better survival rates
🩻 How It’s Diagnosed
-
Oral exam by doctor or dentist
-
Biopsy (definitive diagnosis)
-
Imaging (CT, MRI, PET scans)
-
HPV testing (in some cases)
💊 Treatment Options
Treatment depends on stage, location, and overall health:
1. Surgery
-
Removes tumor ± lymph nodes
2. Radiation Therapy
-
Often used after surgery or for small tumors
3. Chemotherapy
-
For advanced stages or combined with radiation
4. Targeted / Immunotherapy
-
For advanced or recurrent cancer
🧠 Multidisciplinary care improves outcomes.
🛡️ Prevention Tips
-
Quit smoking and avoid smokeless tobacco
-
Limit alcohol
-
Get HPV vaccination
-
Use lip sunscreen outdoors
-
Maintain good oral hygiene
-
Get regular dental checkups
-
Self-check your mouth monthly
📈 Prognosis
-
Early-stage survival rate: ~80–90%
-
Advanced-stage survival rate: much lower
➡️ Early detection saves lives.
Bottom line
👉 Any non-healing mouth sore lasting over 2 weeks needs evaluation.
👉 Mouth cancer is treatable, especially when caught early.
