Linda Stewart asks about a "funny" breast bruise.
Could be an insect bite, maybe a spider - brown recluse spider bites (I've heard) can look like bruises to start with. Have a good doc look at it. Also screen for abuse, although from your description this doensn't appear to be a traumatic bruise. Could she have fallen against, say, a broom handle?
