- Tier 1: Definitive or final diagnosis. Microscopically confirmed via histology or cytology by a board-certified pathologist.
- Tier 2: Presumptive diagnosis. Diagnosis via visualization or imaging without microscopic confirmation.
- Tier 3: Presumptive diagnosis. Based on clinical suspicion only.
