Site-Specific Factor 1

Measured Thickness (Depth)

Notes

**Note 1:** Code measured thickness (depth) of tumor, not size or diameter. Record actual measurement in hundredths of millimeter (mm) from the pathology report. **Note 2:** Use code 991, 993, or 996 if the tumor is resected and the only information about depth is the physician's assignment of a stage value. **Note 3:** Use code 998 if there is no resection of the primary site tumor.
