Grade, Differentiation--Breast: Does SEER agree with our pathologist who contends that "by convention lobular carcinoma is considered to be grade 2"?
No. SEER does not have a default grade code for lobular carcinoma. Code the grade as stated in the pathology report. If no grade is stated, code the Grade, Differentiation field to 9 [Cell type not determined, not stated or not applicable].
