ADA 2026 oral cancer guidelines: biopsy remains gold standard, adjuncts as triage tools

The ADA's 2026 oral cancer screening guidelines recommend biopsy or referral for any oral lesion persisting beyond 10–14 days without definitive diagnosis. Adjunctive tests (e.g., brush biopsy, light-based devices) are acceptable as triage tools but not substitutes for histopathology. Relevant to oral medicine and general practice.
