I've had two more people rid themselves of basal cell carcinoma by wiping on concentrated solution of vitamin C. One used sodium ascorbate and the other buffered C from Life Extension Foundation. Both scabbed up and left clean scars in one to two weeks depending on how large the thing is.
There's no question that vitamin C is a big gun in the anti-cancer arsenal!
This would be a good test to see if a mole is cancerous or not. Just rub on the C solution and if it crusts up and falls off it was, if nothing happens then it's probably not cancer. We know from Dr. Riordan's research that C is toxic to melanoma in cell culture.
