A World Without Cancer — the Story of Vitamin B-17 by G. Edward Griffin

This 1974 documentary by G. Edward Griffin explains the hypothesis that cancer is a "deficiency disease" that is brought about by the absence of Nitrilocides from Vitamin B-17 in people's diets, and it shows evidence that a related medical treatment known as Laetrile is able to often cure cancers that have already started. Various issues are discussed including an explanation of the theory, evidence of the treatment being effective including case histories, and an explanation of ulterior motives causing the medical establishment to inappropriately be opposed to such treatment.
