Link below is to a London newspaper's sensible put-down of a tabloid's specious reasoning as to how cats could be linked to causing PCa.
The tabloid apparently starts by stating, correctly, that the Toxoplasma Gondii microbe exists in cats and their litter boxes, and that this microbe can be responsible for some pretty serious human ailments, most notably birth defects if it gets into pregnant women. That much is true.
But then the tabloid goes on to point out that "… researchers at Indiana University have confirmed a link between Toxoplasma Gondii and cysts forming in the prostate gland."
Therefore, the tabloid claims, men who have been around cats or handled their litter must have picked up the microbe, and the result is it's giving them cysts and probably PCa.
Nonsense, the London paper rightly points out, noting that mere association such as this is not proof. Actually, there could be such an association, but tabloid writing such as this does not qualify as scientific proof of that, the paper notes
The paper then advises its readership "… for anyone reading this, make sure you fact check stories like these, do some digging, inform yourself and only then make your judgments."
