Keith I. Block, MD, of the University of Illinois, is just such a nutrition-oriented cancer

specialist. He makes the interesting, and ironic, point that the clinically well-documented

toxicity of chemotherapy is considered far less of a concern than theoretical worries over

antioxidants. “In fact,” he says, “the toxicity of chemotherapy often leads to a cessation

of treatment, which can directly and definitely adversely impact treatment response and

outcome more often and with far greater ‘evidence’ than antioxidants causing

interference ever could” (personal communication, 2005).
