China Trial Shows 84% Efficacy in Cancer Treatment Using Waste Water Tech

A landmark trial in China has demonstrated an 84% efficacy rate in treating cancer using a method inspired by waste water technology. The approach involves a nano-carbon iron injection, which has halted tumour growth in 16 patients and induced shrinkage in two.
The treatment concept originated from industrial waste water treatment processes, where iron reacts with hydrogen peroxide to generate hydroxyl radicals that break down toxic substances. Chinese scientists adapted this method to target malignant tumours.
Currently, a Phase II trial is underway, involving 52 additional patients, as researchers continue to explore the potential of this innovative approach for advanced, metastatic cancer that has progressed despite standard therapies.
