You will note by some tags that there are a number of unenlightened readers for this sort of topic. One tagged it as laetrile, which has nothing at all to do with Breuss. Another tagged it as quackery because they are too stupid to check with the people who actually have experience with alternative medicine.
My take on Breuss is that his methods have worked for a percentage of practitioners, but the percentage is too low to be attractive to me. Of all the alternative cancer treatments out there, I would suggest you try Jim Humble's MMS or Jason Vale's apricot kernels.
