Russian & Iranian Scientists Use ‘Laser Sword’ to Combat Cancer
Cancer cell
The new non-invasive laser therapy is aimed at treating glioblastoma — the most aggressive brain cancer, which has extremely poor outcomes with standard surgery/chemo/radiation treatment.Developed by a team at Saratov State University in collaboration with Iranian scientists, the method more than doubled survival in animal models, from 34% to 64%.Infrared laser at 1267 nm excites oxygen molecules into reactive singlet form, triggering cancer cell self-destruction while suppressing tumors survival mechanismsUnlike photodynamic therapy, this approach requires no photosensitizers, is non-invasive, and spares healthy tissueThe «laser sword» approach could shift us from cutting or drugs to just using light to fight tumors.
