In this age group men with IGF-I levels in the highest quartile were almost eight times more likely to later develop prostate cancer than were men with levels in the lowest quartile. The researchers conclude that IGF-I levels may serve as an early warning signal for prostate cancer in much the same way as high cholesterol levels serve as an early warning for atherosclerosis and heart disease. They also raise concern that administration of growth hormone and specifically IGF-I to delay the effects of aging in older men may increase the risk of prostate cancer.
