Figure 2. GRB7 expression in benign fibroadenoma and fibrocystic changes.

Examples of images of benign breast cancer tumors stained with the GRB7 antibody (brown) and Hematoxylin (blue). (A) Benign fibroadenoma tissue showing high GRB7 expression (3+) in myoepithelial cells. (B) Benign fibrocystic changes showing no GRB7 expression (0).
