摘要

Mechanisms whereby iron may act in carcinogenesis are induction of oxidative stress, facilitation of tumor growth, and modification of the immune system. Results of clinical and epidemiologic studies demonstrate a strong association between iron excess (even at mild levels) and the development of cancer at any site, but they do not indicate whether this reflects a causal link or an indirect association through other factors (i.e., aging, alcohol consumption, and insulin resistance). Findings obtained from experimental work are not conclusive with respect to a direct carcinogenic role of iron, but they support a carcinogenic or co-carcinogenic role of iron in chemically induced carcinogenesis.
