That looks pretty serious actually. I think you should get her to a vet for an exam. It is suspicious looking like a tumor...... Of course there are some other options that it could be but all need to be checked/treated by a vet. Nothing you can do at home for this I'm sorry to say. Hope this helps. Best wishes.
