This research addresses the critical issue of underrepresentation of racial and ethnic minorities in breast cancer clinical trials. Despite breast cancer being the most diagnosed cancer globally among women, with significant disparities in outcomes among ethnic minorities - the diversity in clinical trials remains insufficient. The authors conducted a rapid review to identify and evaluate strategies aimed at improving ethnic diversity in these trials. The findings highlight the importance of implementing targeted recruitment strategies, enhancing community engagement, and addressing systemic barriers to participation.
