Assessment of serum microRNA-21 and miRNA-205 as diagnostic markers for stage I and II breast cancer in Indian population.

Background: Current markers (carcinoembryonic antigen [CEA] and carbohydrate antigen 15-3 [CA15-3]) lack sensitivity in diagnosis of breast cancer. The aberrantly expressed circulating miRNAs were shown as diagnostic markers in breast cancer. However, there are very few studies from the Indian population.
