Why Early Detection Matters

Survival Is a Staging Story

~60,480 new U.S. oral/oropharyngeal cancer cases & ~13,150 deaths projected for 2026. Roughly two-thirds are found after spread.

Stage at Dx5-Yr Relative Survival
Localized~88.7%
Regional (nodes)~69%
Distant~39%
Early lesions are painless. Absence of pain is not reassurance — it is why these cancers are found late.
Risk Factors

Who Is at Risk — and the Synergy Effect

FactorNote
Tobacco (all forms)Largest single risk; smokeless is NOT safe
AlcoholIncreases mucosal carcinogen uptake
Tobacco + alcohol~15–30× risk vs. neither
HPV-16>70% of oropharyngeal cancers; younger, non-smokers
Age 40+ / maleMost cases; male predominance
Prior lesion / sun (lip)Leukoplakia, erythroplakia, lip vermilion
Screen everyone. "No tobacco, no alcohol" does not mean "no risk" in the HPV era.
The Systematic Head & Neck Exam
Extraoral
  • Face & symmetry; lips/vermilion
  • TMJ: crepitus, deviation
  • Palpate node chains: submental, submandibular, cervical, supraclavicular — bilaterally
  • Thyroid on swallow
Red-flag node: firm, fixed, non-tender, persistent.
Intraoral — 7-Site Tour
  1. 1Labial mucosa & vestibule
  2. 2Buccal mucosa
  3. 3Gingiva & alveolar ridges
  4. 4Tongue: dorsal, lateral, ventral
  5. 5Floor of mouth
  6. 6Hard & soft palate
  7. 7Oropharynx
Tongue Technique
  • Wrap tip in gauze
  • Draw forward & to each side — fully visualize both lateral borders
  • Lift to inspect ventral surface & floor of mouth
  • Palpate for induration, don't just look
Highest-risk sites: lateral/ventral tongue & floor of mouth.
Recognizing Suspicious Lesions

Red Is More Dangerous Than White

LesionMalignant Potential
Leukoplakia (white)Variable; a subset dysplastic
Erythroplakia (red)High — often dysplastic/malignant
Erythroleukoplakia (mixed)High
Worry features: induration, irregular/rolled borders, red/mixed color, ulceration, bleeding, fixed node, non-healing.
The Two-Week Rule & Diagnosis

When to Act

"A bite heals in about two weeks. Anything still here after that, we don't watch and wait — we get it checked."

Referral, Documentation & Scope
Document Every Suspicious Lesion
  • Site (e.g., right lateral tongue)
  • Size in mm/cm
  • Color & surface (mixed red-white, non-wiping)
  • Texture (indurated?)
  • Borders (irregular?)
  • Duration reported by patient
  • Action (dentist notified; referred)
  • Photo with consent — baseline
Scope: RDH screens, documents, educates, refers. Dentist/oral surgeon diagnoses & biopsies.
Sample Chart Entry

"~1 cm mixed red-white, indurated lesion, irregular borders, right lateral border of tongue; non-wiping; patient reports present >1 month. Right submandibular node firm/~1.5 cm/non-mobile. Dentist notified and evaluated same visit; referred to oral surgery for biopsy. Patient educated on tobacco/alcohol risk; cessation resources offered. Referral appointment scheduled; follow-up flagged."
