Oral Cancer (Urgent)

Overview

What is Oral Cancer?

Oral cancer refers to malignant tumors arising in the oral cavity, including the lips, tongue, cheeks, floor of mouth, hard palate, and gingiva. The most common type is oral squamous cell carcinoma (OSCC), accounting for over 90% of cases.

• Sixth most common cancer worldwide
• Higher incidence in males over 50
• Strong association with tobacco and alcohol use
• HPV-related oropharyngeal cancer increasing in younger adults
• Early detection dramatically improves survival
• 5-year survival approximately 65% overall

Overview of the Condition

Oral cancer can present as a non-healing ulcer, red or white patch, lump, or persistent sore throat. It often develops from premalignant lesions. Early-stage cancer has excellent cure rates, but delayed diagnosis results in poorer outcomes. Any suspicious oral lesion persisting for more than 2-3 weeks requires urgent evaluation.

Symptoms and Causes

Symptoms

• Non-healing ulcer or sore (>2-3 weeks)
• Red patch (erythroplakia) or white patch (leukoplakia)
• Lump or thickening in oral tissues
• Persistent pain or soreness
• Difficulty or pain with swallowing
• Difficulty moving tongue or jaw
• Numbness in tongue or lip
• Unexplained bleeding
• Loose teeth without dental cause
• Weight loss
• Neck mass (lymph node involvement)

Causes and Risk Factors

• Tobacco use (smoking and smokeless)
• Heavy alcohol consumption
• Combined tobacco and alcohol (synergistic risk)
• Human papillomavirus (HPV) infection
• Betel quid and areca nut chewing
• Chronic sun exposure (lip cancer)
• Poor diet lacking fruits and vegetables
• Weakened immune system
• Previous head and neck cancer
• Genetic predisposition

Diagnosis and Treatment Options

Diagnosis

• Thorough clinical examination
• Biopsy (incisional or excisional)
• Histopathological analysis
• Imaging (CT, MRI, PET scan)
• Ultrasound for neck lymph nodes
• Staging to determine extent of disease
• HPV testing for oropharyngeal tumors

Treatment Options

• Surgery (primary treatment for most oral cancers)
• Radiation therapy
• Chemotherapy
• Targeted therapy
• Immunotherapy
• Combination therapy based on stage
• Reconstructive surgery if needed
• Rehabilitation (speech, swallowing)

Non-Surgical Care

Non-Surgical Treatment

Non-surgical treatments include radiation therapy, chemotherapy, targeted therapy, and immunotherapy. These may be used alone for patients who cannot undergo surgery, or in combination with surgery for advanced disease.

Supportive Care

1. Nutritional support and counseling
2. Pain management
3. Dental care before and during treatment
4. Speech and swallowing therapy
5. Psychological support
6. Smoking and alcohol cessation programs
7. Management of treatment side effects

Surgical Care

When is Surgery Needed?

Surgery is the primary treatment for most oral cancers, especially early-stage disease. The goal is complete removal of the tumor with adequate margins. Neck dissection may be performed to address lymph node involvement.

Surgical Procedures

• Wide local excision of tumor
• Partial or total glossectomy (tongue)
• Mandibulectomy if jaw involved
• Neck dissection for lymph nodes
• Reconstructive surgery (flaps, grafts)
• Tracheostomy if airway compromised
• Feeding tube if swallowing affected

Anatomy and Affected Areas

Anatomy Overview

Oral cancer can arise in any part of the oral cavity. The location affects prognosis and treatment approach. The tongue (particularly lateral border and ventral surface) and floor of mouth are high-risk sites.

Commonly Affected Areas

• Tongue (most common, especially lateral border)
• Floor of mouth
• Lower lip
• Buccal mucosa
• Gingiva (gums)
• Hard palate
• Retromolar trigone

Frequently Asked Questions

Frequently Asked Questions

QuestionAnswerHow serious is oral cancer?It is a serious condition, but early detection significantly improves outcomes.What are my chances of survival?5-year survival is about 85% for localized cancer, lower for advanced stages.Can oral cancer be cured?Yes, especially when detected early before spread.Will I be able to speak and eat normally?Depends on treatment; rehabilitation helps restore function.How often should I be screened?Annual oral cancer screening is recommended; more frequently if high risk.Can oral cancer come back?Recurrence is possible; regular follow-up is essential.

Prevention Tips

Prevention Strategies

• Avoid all tobacco products
• Limit alcohol consumption
• Protect lips from sun exposure
• Eat a diet rich in fruits and vegetables
• Practice safe sex (reduces HPV risk)
• Consider HPV vaccination
• Regular dental check-ups with oral cancer screening
• Self-examine mouth monthly

Related Conditions

Related Conditions

• Leukoplakia (potentially malignant)
• Erythroplakia (high malignant risk)
• Oral lichen planus (potential risk)
• Oral submucous fibrosis
• Oropharyngeal cancer (back of throat)

Follow-Up Care

Long-term follow-up is essential to monitor for recurrence and manage treatment-related complications. Regular examinations, imaging, and attention to quality of life issues are key components of survivorship care.
