Research appearing in the American Journal of Epidemiology (1991;133 (8):766-75) looked at antioxidant levels in nearly 3,000 men and related the levels of vitamins A, C, E and carotene to the incidence of cancer. Twelve years after the initial testing of the vitamin levels, just over 200 of the men died of cancer. Low levels of vitamin C and carotene was associated with death from cancer. Subjects that later developed stomach cancer had lower levels of vitamin A and C. A low level of vitamin A was associated with cancer in general.
