Taking integrative cancer treatment to its common denominator, I would have to describe it as anything natural and harmless that enhances conventional treatment. Well, something somewhat strange, although fitting that definition, is finding a possible place in the integrative arsenal. Fasting--simply not taking in solid food for a period of time--is being considered as a complementary therapy to chemotherapy. Of course, a nutritious diet along with dietary supplements is usually a key aspect of integrative oncology. And, it will continue as a general rule. However, a new University of Southern California study has shown that a 48-hour fast before and/or after a chemo session will protect normal cells from damage while allowing the cancer cells to receive the effect of the chemo.
