Question:

Behavior--Breast: How is behavior coded when a biopsy shows in situ carcinoma with a focus suspicious for invasion and a subsequent excision/resection shows only in situ carcinoma?

Discussion:

Answer:

Code this case as in situ. The specimen from the excision/resection is the more reliable source for determining behavior, compared to a biopsy, especially in this case where the behavior is ambiguous on the biopsy.
