Vitamin C and Cancer

In my article “How Vitamin C Improves Health” I mentioned that a large intake of vitamin C has value in helping to control the common cold, influenza, hepatitis, schizophrenia, and other diseases. Only a brief mention was made of cancer. Interest in the prophylactic and therapeutic use of vitamin C against cancer is now so great as to justify a fuller discussion of this question. Despite the expenditure of billions of dollars on cancer research, there has been during the last 25 years essentially no decrease in the incidence of cancer or increase in the average time of survival after the patient is diagnosed as having cancer. There is now a real possibility that both the incidence and the average survival time can be significantly improved by use of vitamin C.
