Collaborative Stage

Note 1: Code MEASURED THICKNESS (Depth) of the invasive tumor not size, diameter, or any other measurement. Record the actual measurement in tenths of millimeters as stated on the pathology repot. 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, from a tumor size recorded as 2cm x 1cm x 0.5cm, record 050.
