Recent researches have shown that certain vitamins can be successfully employed in the fight against cancer and that they can increase the life expectancy of some terminal cancer patients. According to recent Swedish studies vitamin C in large doses can be an effective prophylactic agent against cancer. Noted Japanese scientist, Dr. Fukunir Morishige, and his colleagues who have been examining the healing potential of vitamin C for the last 30 years, have recently found that a mixture of vitamin C and copper compound has lethal effects on cancer. According to several studies, vitamin A exerts an inhibiting effect on carcinogenesis. It is one of the most important aids to the body's defence system to fight and prevent cancer. Dr. Leonida Santamaria and his colleagues at the University of Pavia in Italy have uncovered preliminary evidence suggesting that beta-carotene, a precursor of vitamin A may actually inhibit skin cancer by helping the body thwart the cancer-causing process known as oxidation.
