Cancer Treatment Revolutionized by CERN's Millisecond Flash

What Happened Researchers at CERN, the European physics laboratory famous for the Large Hadron Collider, have successfully adapted particle accelerator technology to create FLASH radiotherapy—a cancer treatment that compresses weeks of radiation into millisecond bursts. The technique delivers over 40 Gray of radiation (equivalent to 20 conventional sessions) in less than 0.1 seconds, using 200 MeV linear electron accelerators. Physicist Walter Wuensch leads the multimillion-dollar project, working alongside Institut Curie researchers Vincent Favaudon and Marie-Catherine Vozenin.
