Answer
Its hard to see fro the photo, but this doesnt seem to be in a place where mammary tissue is. Is this more toward her side (where it originates) or on her back more?  It looks vascular, which means its not an abscess since abscessse are pockets of infection and pus, they do not have a blood supply where tumors do.    Please let me know your location. I have a database for the US, Canada, the UK and other areas so perhaps I can find someone to help.  This thing needs removed...that much I know.
