You will have to get a vet to check this to be sure. He will need to biopsy this lump and have it sent to a lab for confirmation. Maybe a cyst, or could be tumor (cancer) which may or may not be malignant. Only your vet will be able to confirm this. Times a wasting. Good luck to you and her. Let us know what you found out.

Google "mastitis".
My guess is she has an infection in the milk gland.
