You are quite right, nothing is 100%. No two people and no two cancers are the same, and there is no magic bullet anywhere that always works for all people.
For the record though, I have hosted the Yahoo Oleandersoup Group for over five years. It now has almost 1100 members. In all that time only one person has joined the group and followed the protocol who is not still alive. That person came to us after several years of chemo and radiation with scant weeks to live, virtually no immune system and damage to his major organs that was irrepairable. He died of liver failure, no doubt from his prior mainstream chemo.
I know those figures sound incredible but I must point out that not every member of the group has cancer. Some have HIV, some Hep-C, many are there for the information and a good number of people are there who are naturopathic practitioners or otherwise experts on cancer or natural healing.
