I'm curious as to what type of diseases wizards can get. What are the symptoms of said diseases? Are they much different from Muggle illnesses? Can wizards get Muggle sicknesses? Like, cancer or heart disease? JKR hasn't really written much about that kind of thing. Just Spattergroit and Dragon pox, if I can recall. I mean, St. Mungo's can't be just for snake bites and awry jinxes, can it?
