Horses, like kids on a playground,
seem to have a continuous array of lumps and bumps on them at various times,
and in various places. It’s a rare
horse that you don’t find some sort of lump when running your hand over
them. Quite often, these lumps are
benign, or have been there for years without change and are really nothing to
be concerned about. That said
there are times that a horse can develop a mass that can have severe
consequences for the health of the animal.
