I just received a surgical pathology exam test result. The grade is “GRADE 1-2/3" and I don’t know what this means. Is it grade 1 to 2 out of 3? Or maybe grade 1 and ⅔ (1.67)? 

I’ve pasted below details from the test result, in case they’re helpful in answering my question.

A. Breast, Right, Right breast- upper outer quadrant. Tissue A-C, Ca++ A,B: DUCTAL CARCINOMA IN SITU

HISTOLOGIC TYPE: DCIS, PATTERN(S) SOLID AND CRIBRIFORM WITH COMEDO NECROSIS 

GRADE 1-2/3, WITH ASSOCIATED MICROCALCIFICATIONS.

Estrogen Receptor (ER) Status Results: Positive
