The blog NHS Choices (February 10, 2014) noted that “there has been increasing anecdotal evidence that vitamin C may still be useful as an anticancer medicine if used in high concentrations and given directly into the vein (intravenously).” Explain what it means that there is “increasing anecdotal evidence” that Vitamin C may be a useful anticancer medicine. How does anecdotal evidence contrast with scientific evidence? What kind of conclusions, if any, can be made from anecdotal evidence?
