China trial: iron-based cancer therapy shows 84% efficacy in advanced cases

Chinese scientists report a landmark clinical trial where an iron-based therapeutic approach, inspired by wastewater treatment chemistry, achieved 84% efficacy in patients with advanced metastatic cancer who had exhausted standard options. The mechanism leverages iron's reaction with hydrogen peroxide to generate hydroxyl radicals that target tumor cells. If corroborated, this could represent a novel, broadly applicable cancer treatment, though the specific trial design, patient numbers, and peer-review status remain unclear from the report.
