Note 1: Code measured thickness (depth) of the invasive tumor only, not size, diameter, or any other measurement. Record the actual measurement in tenths of millimeters (mm) as stated on the pathology report. Do not record the measurement from a radiographic report.
Note 2: Record the measurement labeled specifically as thickness or depth of tumor. In the absence of a label, use the "cut surface" dimension, or the third dimension from a description of 3 dimensions (N1 x N2 x N3). For example, for a tumor size recorded as 2 centimeters (cm) x 1cm x 0.5 cm, record 050.
