Canine Oncology – Canine Lymphoscarcoma

Canine lymphosarcoma (LSA)

Canine lymphosarcoma (LSA)


An expert in the treatment of animal diseases, Todd L. Prince, DVM, delivers quality veterinary care at Naperville Animal Hospital, Springbrook Animal Care Center, and several associated Illinois clinics. Dr. Todd Prince’s professional interests include cancer as well as neurological conditions in small animals.

Dogs can present with a variety of cancers. Canine lymphoscarcoma (LSA) ranks among the most common types. The cancer begins when immune cells called lymphocytes start to multiply without check and form tumors.

Because lymphocytes are distributed throughout the body, tumors can start growing anywhere, meaning the warning signs of LSA vary widely depending on the individual circumstances of the dog in question. However, early-stage LSA often presents as swelling in a lymph node or in lymph nodes.

Veterinarians treat LSA with chemotherapy and radiation. In fact, LSA responds very well to chemotherapy drugs, which cause most canine patients’ LSA to enter into remission for anywhere from 6 to 9 months.

In their natural setting, small animals avoid showing signs of illness or injury as a survival mechanism. This can make it difficult to tell when a rabbit, guinea pig, mouse, or rat is not feeling well. Pay attention to your pocket pet, and plan a trip to the veterinarian if he or she displays any of these warning signs.

1. Keep a close eye on small animals that have a sudden change in appetite. This is especially important if weight loss occurs.

2. Changes in elimination can indicate a problem. Loose stool is of particular concern.

3. Changes in appearance signify a health problem. Be on the lookout for abnormal discharge, the appearance of blood, or a dull coat.

4. Pets that seem weak, twitchy, or inactive should see a vet as soon as possible.
