Right Breast
06/27/2002 exc bx, DCIS. Margins involved.
09/24/2002 re-exc, several foci of intraductal ca. Margins involved.

Radiation treatment started 11/18/2002.
Is this 1, possibly 2, or maybe 3 breast primaries because of the 2 month rule and no statement of "recurrence"? Based on SINQ #20000478, this would be at least 2, but possible 3 primaries. Based on SINQ #20021143, this would be 1 primary if the case were diagnosed from 1998-2003. The excisions appear to represent wider excisions of the same tumor.
Answer:
For cases diagnosed prior to 2013:
For tumors diagnosed prior to 2007, this is one primary, assuming these are wider excisions of the same tumor.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
