I agree this does sound too scientific to me. However, I would say don't discount diet and the effects it has on health and cancer. From what I have read and heard changing the diet of people with prostate cancer can have amazing effects. I would recommend a couple of really good (i.e. not quackery) books:
Anticancer: A New Way of Life - by David Servan-Schreiber, M.D., Ph.D
The China Study - T. Colin Campbell (a bit of an academic read but an excellent book)
good health to you all
