Dr. Weeks’ Comment:  Paradoxical though it seems, the use of anti-oxidants while undergoing oxidative therapies (chemotherapy and radiation) for cancer has been shown to be of benefit for the patient.   The rationale is not entirely clear but it seems that the rescue effects of anti-oxidants serve primarily the healthy  cells while the cancer cells are not aided.

His conclusions are that the data suggest benefit from antioxidant use during chemotherapy and he cautions that treatment must be individualized.
