I have a friend who is fighting adv BC, and she is following the "The Cancer Battle Plan" program, which is not too different from Gerson. SHe does frequent 7-day juice fasts. TO date, all her tumors have dissappeared except the ones inthe bone, and they have not progressed. I recomend that you read "Antioxidants Against Cancer" for some good advice on your suppliment list. You should add CoQ10, Alpha lipoic acid, and a few other suppliments to your list. Also, you should be taking a high-quality high-trypsin enzyme such as Omnizyme Forte, Megazyme Forte, Wobenzyme Forte, etc.
I am sure that Gaylen will recomend ozone, and I currently have no experience with this. You shoudl consider buying some food-grade 35% h2o2 and using it for baths, etc. THere is a peroxide enema protocol in "FLood Your Body With Oxygen" that I have been contemplating as a potential replacement for coffee.
