MTMR3 and Fibroadenoma: While MTMR3 (Fig. 2) is a statistically significant discriminator of all four groups (except non-metastatic from metastatic): non-metastatic from fibroadenoma (cutoff > 4.18), non-metastatic from control (cutoff > 1.0), metastatic from fibroadenoma (cutoff > 4.18), metastatic from control (cutoff > 1.0), and fibroadenoma from control (cutoff > 1.0).
