  • Fibrosarcomas are a type of soft tissue cancer that is common in dogs. They are most often found on the limbs and trunk of the body but can also be found in the nasal cavity or mouth. They usually originate from the connective tissue of the skin and beneath the skin, but occasionally from the bone. Older dogs and certain breeds (especially large breeds) are at greater risk. Fibrosarcomas are often painful. Surgery is the treatment of choice for fibrosarcomas, with or without radiation and/or chemotherapy. With proper and prompt treatment, favorable outcomes are possible.

  • Usually caused by a bite from another cat, fight wound infections can lead to the development of an abscess (a pocket of pus) or cellulitis (pain and swelling in the area of the bite). A cat’s sharp canine teeth can easily puncture the skin of another cat, leaving small, deep, wounds that seal over quickly, so it is important that your cat is seen by a veterinarian for treatment as soon as possible after being bitten.

If a negative reaction occurs, please call your veterinarian.

  • Fine needle aspiration is a useful tool to collect samples for cytology and is often used to diagnose abnormal lumps on your pet's body as well as evaluation of fluid samples and tissue surfaces.
