I have inflammatory Breast Cancer and followed this diet to the T under the DAILY supervison of Frances Hart (Col. Joe) I had been on the diet religiously for 9 months. When I started the diet in July 2002, I had a 3cm tumor in my right breast and one in my lymph nodes. As of April 23, when I received the results of my pet, cat and bone scan, I found out that my core tumor had grown to 13cm x 10.4cm, plus the cancer has spread to my liver with 2 large masses both over 7 cm and 5 new tumors in breast and lymph nodes. So as you can see, oxalic acid may work for some cancers but it does not work on Breast Cancer without an Estrogen Blocker. If you will check pg 29-30, read the testimonial of Diane T. She states the diet was not effective for her until "she started taking an estrogen blocker and airida (bone cancer med) So BEWARE! I also went in to kidney failure and had to deal with that. The oxalic acid diet suggest the use of sugar, non organic foods, canned carrot juice plus canned foods,chicken, hot dogs, chocolate, etc., and other processed foods. I'm now on Dr Breuss's cancer diet. There is no comparison between Oxalic acid diet and Dr, Breuss. Stay with Dr. Breuss cancer diet, it's pure! I had a chance 9 months ago, now I'm in Stage 4 with 6 months to live. You decide!
