Stomach Cancer Was Napoleon's Waterloo: Study
"Today's treatments wouldn't have kept him alive, researchers contend"
"According to Genta, the salted meat eaten by soldiers of the time could have harbored a bacterium that causes stomach cancer. Napoleon's medical history, Genta said, suggests he was infected by the germ."
I cannot see that the French Army relied on salted meat - so far it seems to me that meat was delivered fresh or raw, the salted meat theory is a sad joke in my opinion, I see quite a positive family history of gastric cancer, while it may not be heridary it is for sure a predisposal, at least in my medial field I always check for diseases running in the family and a positive history will lead to much earlier further diagnosis than otherwise.
I won't bore you with other medical details and diseases to realize how important genetic predisposal is.
