Answer:
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 14 [invasive and in situ components present, size of entire tumor coded in Tumor Size AND in situ described as minimal (less than 25%)]. The pathologist did not use a code as defined by SEER. For cases described as "less than or equal to 25%", choose the lower of the two EOD code choices.
