IGF-1

Based on a study of rats, lead investigator William E. Sonntag, PhD, and colleagues at Wake Forest found that reduced levels of IGF-1 reduced cancer risk by about 45% and decreased cancer deaths by 12 to 15%.

Cancer risk increased when the animals were given growth hormone, which elevates levels of IGF-1 levels in the blood.

A small amount of IGF-1, naturally produced by the body, appears harmless, noted Dr. Sonntag. The key roles of IGF-1 are increasing cell growth and preventing cell death. But too much IGF-1 might be dangerous. “Elevated IGF-1 levels in pre-menopausal women have been...
