1. Why early detection matters — epidemiology and risk factors

Course overview

Oral and oropharyngeal cancers remain among the most important soft-tissue diagnoses a dental team can influence. Early detection improves treatment options and survival. This course is designed as 1.5 hours of verifiable CPD and maps to GDC Development Outcomes A, C and D.

Suggested study time

• Epidemiology and risk factors — 15 min
• Structured soft-tissue examination — 20 min
• Red-flag lesions and differential diagnosis — 25 min
• Urgent referral pathways — 15 min
• Communication, documentation and safety-netting — 10 min
• Knowledge check (MCQ) — 5 min

GDC Development Outcomes

• Outcome A: Effective communication with patients — explaining findings, next steps and the reason for urgent referral.
• Outcome C (primary): Maintenance and development of knowledge and skill — recognising potentially malignant disease and oral cancer is a core clinical responsibility.
• Outcome D: Behaviours that maintain patient confidence and public trust — timely referral and accurate records support patient safety.

UK context

Incidence of oral and oropharyngeal cancer has risen in recent decades. Many cases present late. The dental team sees patients regularly and is uniquely placed to examine the mouth and neck, spot change, and act.

Major risk factors

• Tobacco in any form (smoked and smokeless)
• Alcohol — risk rises with higher consumption; combined tobacco and alcohol multiplies risk
• Human papillomavirus (HPV) — particularly relevant to oropharyngeal cancers
• Age — risk increases with age, but do not ignore younger adults with red-flag features
• Betel quid / areca nut use where culturally relevant
• Previous oral cancer or potentially malignant disorder
• Immunosuppression and some systemic conditions
• Poor diet / low fruit and vegetable intake (contributory)

Opportunistic screening in practice

Every new patient examination and routine recall is an opportunity to:

• Update social and medical history (tobacco, alcohol, HPV-related risk conversation where appropriate)
• Perform a full soft-tissue examination
• Photograph lesions of concern (with consent) for monitoring or referral
• Give brief advice on smoking cessation and alcohol reduction, and signpost support

Key message: early detection is a team skill — dentists, hygienists, therapists and nurses all contribute to noticing and escalating change.
