Shining a brighter light on brain tumors: new therapy shows promise

This study tested a new way to treat glioblastoma, an aggressive brain cancer. During surgery to remove the tumor, doctors used a special light therapy (photodynamic therapy) to kill remaining cancer cells. The goal was to find the highest safe light dose. 14 patients took part, and the treatment was added to standard care (surgery, radiation, and chemotherapy). The study aimed to see if this approach could help control the disease without causing too many side effects.
