FLASH Proton Radiotherapy Spares Normal Epithelial and Mesenchymal Tissues While Preserving Sarcoma Response

Scientists studied proton radiotherapy (PRT) damage to skin and mesenchymal tissues of muscle and bone and found that flash PRT of the C57BL/6 murine hind leg produced fewer severe toxicities leading to death or requiring euthanasia than standard proton-PRT of the same dose.
