- Note 2: Use code 001 when tumor is described as unifocal; arising from or occurring in a single focus or location.
- Note 3: The AJCC definition for multifocal tumor differs from the MP/H definition for Multiplicity Counter. Use code 002 for any tumor with multiple foci, even if foci are not measured.
