Here's something a little different to research. Your friend may like to try Almonds... not as a cure, but more of a preventative measure after regular treatment has begun - during the remission/healing phase... the scary phase. Not too many... just 3 per day... no more... no less.
"The almond, Prunus amygdalus, is closely related to the peach, Prunus persica (also called Amygdalus persica), and likewise to the apricot, Prunus armeniaca. The almond nut is of two distinct types, the bitter and the sweet. The bitter almond contains a ferment, emulsin, which in the presence of water acts on the glucoside, amygdalin, and yields glucose, benzaldehyde and hydrocyanic acid. Amygdalin, of course, is present in the sweet almond, but not the ferment, emulsin. It is interesting to note that a cancer therapy, Laetrile, which has been discredited and banned by government authorities, is described as an extract from the apricot kernel, and is for the most part hydrocyanic acid. It has been hypothesized by the discoverer that this acid is destroyed in the body by normal cellular oxidative metabolism, but cancer cells, functioning without oxidative mechanisms, are unable to destroy the acid; thus they absorb it and are destroyed themselves....", William A. McGarey, M.D.
My translation:
Almonds taken over a long period of time, in small doses may be very benefitical for your friend to prevent remission - but NOT as a cure. Hydrocyanic acid is an extremely deadly poison on it's own. The human digestive system seems to break this down, but Cancers cells may have difficulty doing so and are thus kept in remission after regular treatment.
As always... consult a Doctor about specific diets and by all means discuss Almonds with your Doctor too.
Hope your friend gets better.
