I am the father of a 29 year old who is near the end of her chemo with an apparent very good response. Although her physician is not supportive of alternative therapies, we are preparing to begin a preventative regime when she completes that. An RN, always interested in nutrition, I have now undertaken a major project of researching the literature, and believe beyond a shadow of a doubt that we can reduce the likelihood of cancer very significantly, (far beyond what the traditional medical community would ever believe) and if contracting it, can usually treat it successfully with very specific nutritional approaches.
In my search for legitimate information, I usually rejected information I couldn't replicate from other sources. And I pursued vigorously information consistent with other data that I found. I found the very bust summary of this information in the book How to Prevent and Treat Cancer with Natural Medicine; Murray, Birdsall, Pizzorno, Reilly. This is a summary documentation in an easy read format of over 4000 different pieces of research. I don't understand how the traditional medical community can refute this information, other than to just ignore it. This isn't left field stuff. Its logic scientifically studied and proven information.
And you are asking the right question. For if we make no changes to lifestyle after successfully treating cancer, the conditions that first existed that allowed for the cancer to start, are back in place again, waiting for the inevitable.
God build our bodies as incredible fighting machines, but we do have to give them the right ammo.
Blessings...
