Hi Alicia, I have recently (Aug 2005) had an op. for colon cancer, and have done a lot of research since getting out of hospital. You'll find the fruits of this research on a non-commercial, no-hype website:
http://www.self-helpcancer.info. There are details of the diet I have adopted, and the research behind it (all in layman's terms). I hope this helps. I have bags of energy on this diet, tho' get zapped fortnightly by the chemo. Ask me in a few years time whether it works in my case! Turmeric (curcumin) is one of the useful things for colon cancer.
