The significance of exosomal microRNAs (EmiRs) in breast cancer (BC) diagnosis has been widely addressed over
the past decades. However, little information is still available regarding these reliable biomarkers’ impacts on BC
early diagnosis, prognosis, and treatment outcome predictions, but their great potential in spotting BC early and
their predictive essence in BC prognosis and treatment results are promising against this common cancer. The
present review focuses on the most recent findings and advancements of EmiRs applications in BC early diagnosis
and treatment prediction and identifies current helpful EmiRs that are widely used in this regard
