Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Coco and for providing a picture of her lump, that is very helpful. I'm not sure when you last discussed having it removed with her vet, but given that it has grown more and is bleeding, I think you should discuss removing it again. Due to her age, there is a chance this lump could be cancer, but it needs to biopsied first before any determination could be made as to whether or not it's cancer. I'd schedule an appointment with her vet. I hope this helps.
