I've often wondered about that sort of thing actuall. For example, some people wind up with cancer for no particular reason. Didn't smoke, didn't drink, but yet....

Others, like myself, have a definite cause. In my case, pipes and cigars mostly, cancer started on a spot on my tongue where the smoke would most likely hit.

So, is there a difference in these types? Does one have a more successful cure rate than the other? Should one type be treated differently than another? Seems that when all is said and done, it's a "cookie cutter" approach with minor philosophical differences between institutuions. But should it be?
