RE: Common ceratopsian horn ailments

I read recently (will look for the reference) that evidence was found of
"bone cancer" in a torosaurus fossil.  What that evidence was, I'm not sure,
because I don't recall the specifics.  Nevertheless, I'll look for the
source tomorrow.

        What, if anything, does the fossil record tell us about common
        ailments of ceratopsian (or ceratopian, if you prefer) horns? 
        Breakage, problematic rehealings (if this happened), rot, possible
        problems due to prior malnutrition, whatever.

        If there is a decent amount of material, if it genus or species
        specific or common to all ceratopsians?

        Most importantly, how would it manifest itself physically?  For
        instance, how would part of a horn have broken off? Please be
        if you can so that I get a decent idea of what I'd be looking at if
        were standing a few feet from the head of the animal.

        An odd question, but thanks for any help,
