Research on and discovery of circRNAs in BCa. The amount of research, as quantified by the annual number of peer-reviewed publications, has been relatively stable for mRNAs (orange line) but not for circRNAs (blue bars) in the following categories: a overall, for any subject or disease; b oncology; and c BCa. d Increasing numbers of novel circRNAs were identified from 2016 to March 2020
