I am sorry you are worried about Xena. Where on her body is the lump?Many large lumps on dogs are benign fatty tumors, called lipomas. However, it could be more serious; about 15 to 20% of lumps on or below the skin on dogs are not benign. The only way to tell what a lump is, if it is cancer or benign, if it needs to be removed or not is to do FNA, fine needle aspiration. We put a sterile needle into the lump, to get a sample to stain and examine under a microscope. If only fat cells are seen, it is probably a lipoma. If abnormal cells are seen then the lump should be removed.Pleae let me know what other questions you have and if this is helpful!
I did not hear back from you; I hope you were able to see my answer! Can I help with anything else?
