#1: Revised Breast EOD Codes. June 25, 2002
#2: SEER EOD-88, 3rd Ed, 3-4,110a
Prior to January 1, 1998: If size of invasion is not given, and the total tumor size is < 1 cm, code EOD-Size of Primary Tumor to 009. If the total tumor size is < 2 cm, use code 019. If the tumor mass is > 2 cm, code size as 999. The EOD manual states, "If only one size is given for a mixed in situ and invasive tumor, code size to 999, unknown."
For breast cases, if the size of the invasive component is not given, record the size of the entire tumor from the surgery report, pathology report, radiology report, or clinical examination, and document how the size was determined in the EOD-Extension field.
