LUMPS IN DOGS AND CATS

All lumps are abnormal. That is the important message. You should get your veterinarian to check any lump. Sometimes they are a simple cyst or some form of skin disease but sometimes these lumps are cancerous. 

Pictured below is a cytology of a benign fatty cell mass called a Lipoma. These fatty lumps are very common in old dogs but should always be checked because they can be mistaken for connective tissue sarcomas or liposarcomas. Always ask your veterinarian to do a fine needle aspirate of any lump for cytology.

SKIN CANCER IN DOGS AND CATS

Canine Mast Cell Tumors
Canine Mast Cell tumors can take many morphological appearances and are often mistaken as "nothing to worry about" when in fact they are very serious indeed and potentially fatal due to metastatic malignant behaviour.
Here is some examples of canine mast cell tumors



At Treendale Pet Medical we will investigate any skin mass by taking a fine needle biopsy or FNA and examining this under the microcope. If we suspect a MCT, we will stage the tumor with blood tests, ultrasound and radiographs as well as checking the local lymph nodes for any evidence of metastasis (spread). Are you worried about your dog's MCT? Read about treating mast cell tumors here

Canine MCT can present in many different forms. You must get all lumps checked by your veterinarian.

BONE CANCER IN THE DOG

Osteosarcoma

Osteosarcoma is one of the most common bone cancers in dogs. It is unfortunately common in the large and giant breeds especially rottweillers, German Shepherds and Great Danes to name a few of the more susceptible breeds. Bone cancers are very painful and respond poorly to analgesia. If your pet has a hard bony swelling and lameness, it should be radiographed. Make sure your vet takes x-rays.

ORAL CANCER OF THE DOG AND CAT

Oral cancer is very common in the dog and cat, possibly due to chonic infection of the mouth due to dental disease and the chronic immunoresponse to chronic inflammation, local infection and toxaemia. Healthy teeth and gums are important for our holistic health!
Melanoma is the most common cause of cancer in the mouth of dogs. Squamous cell carcinoma (SCC), fibrosarcoma and osteosarcoma are also common oral cancers in the dog. Mast cell tumors and lymphoma are also sometimes seen in the mouth or gums of dogs. All lumps should be checked by your veterinarian. In cats, squamous cell carcinoma is the most common oral cancer.
