We cannot discount the role of food in fighting off cancer. I was diagnosed with late-stage ovarian cancer in 2007. (Dr. Richards was on the team--he is wonderful!) I like to say that surgery and chemotherapy put me into remission and that changing my lifestyle has helped me stay that way 9 years later. After much reading and educating, I adopted a whole food, plant-based diet consisting of an array of grains, fruits, vegetables, and legumes. I urge other survivors to check out the many resources, such as PCRM's Cancer Project: http://www.pcrm.org/health/cancer-resources/the-cancer-project. There is substantial evidence that eating a plant-centered diet, low in fat, sugars & processed food, helps the body fight cancer.
I'll gladly provide other resources and information.
