how widely is it known in the general populace,that most dogs can be cheaply and easily trained to sniff out at an early stage non clinically presentable common deadly cancers....to up to 90% accuracy long before a scanner can pick them out.
Why not just take B-17 ....found in apricot seeds, BITTER almonds, millet.....just google it.
This is like Vit. C to scurvy.
So the question I would put to you is......what if cancer is a preventible disease?
