A quote from the following paper...
"Rats implanted with the Walker 256 adeno-carcinoma were treated by simply replacing
their drinking water with dilute solutions of commercial hydrogen peroxide... the rate of cure is on the average 50-60%.
The time taken for complete disappearance of the tumour is usually 15-60 days. So far, 72 rats have been cured."
