ADVICE

Follow Precancer Lesions Every Three Months

  • Do follow precancer patients every three to four months initially to establish lesion stability.
  • Advise lifetime follow-up and biopsy promptly if architecture, opacity, red speckling, or ulceration appear.
ANECDOTE

Ten Year Clear Outcome After Tongue Ablation

  • Paras described a patient whose tongue lesion was ablated and remained clear for 10 years with clustered early follow-ups.
  • He contrasts this with other patients showing persistence, underlining lesion heterogeneity and variable outcomes.
ADVICE

Use Two Weeks For Trauma But Biopsy High-Risk Leukoplakia Now

  • Use a two-week threshold for traumatic or transient ulcers before biopsy, but biopsy immediately if leukoplakia shows 'cracked mud' or high-risk features.
  • Prioritize biopsy sites with heterogeneity, red speckling, papillary changes, or high-risk oral sites.
