This is always the question when we find a lump, bump, or swelling. The doctors at Pender deal with this question several times every day and with their knowledge of age, breed, location, feel, shape, etc., they will know the correct direction to move in order to get a definitive answer. A small sample of cells taken into a syringe, placed on a slide, stained, and observed on a microscopic slide is often all that is needed to aid the diagnosis. If necessary, a pathologist will read the slide, or a biopsy will be taken for the pathologist to check with a microscope. Just as with human bumps and lumps, early diagnosis improves likelihood for successful treatment!
