So sorry to hear of your fathers illness. I read an article in the paper about a British journalist who had stomach cancer and embarked on some kind of holistic diet which involved eating only organic vegetables in large quantities, and in different ways, ie. some of them were juiced, some eaten raw, etc. The way it worked was to put her bodies chemical make up back to how it should be, and to clear out all the pollutants. Within twelve months the cancer had disappeared altogether.
