Which French emperor died of cancer?

how come on when I play group battles the correct answer to "How did Napoleon die" is given as Arsenic poisoning.

I agree with Magsmadmaxman.

DONNA, no, it was fron the pigment used in the wall paper. Bacteria broke it down and released the fumes into the air, over time the poison accumulated in Napolion's body and he died. the proof was in a lock of his hair.

clivo, well it was the 1800's. I think it's plausible he was poisoned. Nobody wanted a version 3.0

I thought he was poisoned by Arsenic from the buttons on his jacket.
