"Hormonal milk is very different than natural milk. Hormonal milk is often contaminated with pus cells, resulting from mastitis in cows due to hyperstimulation of milk production, and also with antibiotics used to treat the mastitis. Other abnormalities include increased fatty acids, which are incriminated in heart disease... More importantly, hormonal milk contains high levels of a growth factor (IGF-1), which has been incriminated as a major cause of breast, colon, and prostate cancers. However, these risks are avoidable. according to the Hartman Group, a prominent Seattle consulting firm, organic milk is now among the first organic product that consumers buy. Organic milk is also becoming increasingly available." ("Hormonal Milk Poses Greater Risks Than Just Twinning," Cancer Prevention Center press release; June 27, 2006)
