Mechanism: How Tobacco Causes Oral Cancer

Tobacco exposure introduces carcinogenic substances into the mouth. This leads to:

  1. DNA damage and cellular mutation in the oral mucosa
  1. Development of premalignant lesions, including:
  • Leukoplakia – white patches
  • Erythroplakia – red patches
  • Oral Submucous Fibrosis – fibrotic tissue bands
  • Tobacco Pouch Keratosis – wrinkled and leathery inner cheeks
  1. Ingredient and Without intervention, these can progress to:
  • Oral Squamous Cell Carcinoma, marked by ulceration, tissue invasion, and abnormal growths

Premalignant Lesions: Early Warning Signs

Premalignant or precancerous lesions are abnormal changes in the mouth’s lining that can precede oral

cancer:

  • Leukoplakia
  • Erythroplakia
  • Oral Submucous Fibrosis
  • Tobacco Pouch Keratosis

Oral Cancer: Symptoms and Sites

Oral squamous cell carcinoma is the most common oral cancer and may affect:

  • Tongue
  • Floor of the mouth
  • Inner cheeks

Common symptoms include:

  • Non-healing ulcers
  • Lumps or thickened tissues
  • Pain or difficulty in chewing or swallowing
  • Numbness in the mouth

Prevention Strategies

Preventing oral cancer starts with:

  • Routine dental check-ups
  • Early diagnosis of abnormal lesions
  • Correction of oral irritants
  • Complete cessation of tobacco products

Tobacco Cessation

Effective options for quitting include:

  • Professional cessation counseling
  • Support networks and therapy
  • Nicotine Replacement Therapy (NRT)

Nicotine Replacement Therapy (NRT)

NRT reduces cravings via controlled nicotine doses:

  • Nicotine patches – skin delivery
  • Nicotine gum – oral absorption
  • Nicotine lozenges – dissolve in the mouth
  • Nasal sprays – rapid absorption
  • Inhalers – simulate smoking action
