The nutritional approach focused on through these cases addresses deficiencies in dietary phytonutri- ents known as Salvestrols along with their co-factors. Salvestrols operate through a highly targeted mechanism that hinges on their metabolism by the universal cancer marker CYP1B1. This results in a very broadly applicable method in addressing a nutritional deficiency to the benefit of patients. Unfortunately modern farming practices have severely limited the availability of these specific phy- tonutrients in the modern diet. These phytonutrients are all phytoalexins and are not induced in abundance until the plant comes under attack from infection or predation. Six cases of recovery from cancer using this nutritional approach are discussed. To illustrate the breadth of this approach cases are presented representing five diverse cancers: breast; prostate; colon; liver; and Hodgkin’s lym- phoma. Two of the cases show how rapid and dramatic the improvement can be when nutritional Introduction
