CERN's particle accelerator tech is being reimagined to blast cancer in under a second

A new cancer treatment called Flash radiotherapy delivers intense radiation in under a second, aiming to kill cancer cells while sparing healthy tissue. Early mouse experiments show reduced side effects compared to traditional radiotherapy. CERN is adapting its accelerators for this therapy. Human trials are ongoing worldwide, with potential applications for brain tumors and metastatic cancers. Researchers are exploring various radiation particles. Challenges remain in making the technology accessible and affordable for widespread use.
