This review examines the influence of a reduction in caloric intake on cancer and
longevity. Data indicating that rodents subjected to caloric restriction display lower
tumor incidence, reduced susceptibility to carcinogens and extended lifespan is analyzed.
The potential role of the growth hormone/insulin-like growth factor type 1 (IGF-I)
axis in this effect is discussed as is the evidence that a reduction in growth hormone
and/or IGF-I leads to a reduction in spontaneous tumors and susceptibility to carcinogens.
