Proceedings of the National Academy of Sciences, Volume 123, Issue 11, March 2026. <br/>SignificanceExtrachromosomal circular DNA (ecDNA) is a powerful driver of cancer evolution, enabling tumor cells to rapidly amplify oncogenes and develop drug resistance. Yet, how ecDNA forms inside cells has remained a long-standing mystery. Here, we …
