Site-Specific Factor 1

Measured Thickness (Depth), Breslow Measurement


**Note 1:** Code MEASURED THICKNESS (Depth) of tumor (Breslow measurement), not size. Record actual measurement in hundredths of millimeters from the pathology report. **Note 2:** Code the greatest measured thickness from any procedure performed on the lesion, whether it is described as a biopsy or an excision. * For example, if a punch biopsy with a thickness of 0.50 mm is followed by a re-excision with a thickness of residual tumor of 0.20 mm, code 050 * Do not add measurements together from different procedures
