Book excerpt: Here are 62 case histories proving beyond any doubt that Laetrile (Vitamin B17) works in the control of cancer. These are not anecdotal stories or cases of people who never had cancer in the first place. Each history is authenticated by a firm diagnosis and meticulous medical documentation. This book also recounts the personal battle of Dr. John Richardson who incurred the wrath of orthodox medicine when he and his patients elected to use vitamin therapy instead of surgery, drugs and radiation as the treatment of choice.
