Having read a lot of different books concerning cancer and diet links, the ones I most believe are by Peter J. D'Adamo: Eat Right for Your Type, series which include a book written about cancer diets, with supplements. Another author is James D. Krystosik with Carbs form Heaven, Carbs from Hell.
These authors explain (in English) How your body works down to the cell molecule level. Instead of gerneric claims of success, they focus on you individually.
I borrow these from the library, no charge is nice, and your library can request them if they do not have them on the shelf.
