High-dose injections of vitamin C reduced tumour weight and growth rate by about 50 percent in mouse models of brain, ovarian and pancreatic cancers, report researchers from the National Institutes of Health. The researchers traced vitamin C’s anticancer effect to the formation of hydrogen peroxide in the extracellular fluid surrounding the tumours. Normal cells were unaffected. In their laboratory experiments on 43 cancer and 5 normal cell lines, the researchers saw that high concentrations of vitamin C had anticancer effects in 75% of cancer cell lines tested.
