Cutaneous LymphomaĬutaneous lymphoma tends to appear first as dry, flaky, red, and itchy patches of skin anywhere on the body. Other common symptoms include loss of appetite, lethargy, weight loss, swelling of the face or legs ( edema), and occasionally increased thirst and urination. The most common initial symptom of multicentric lymphoma in dogs is firm, enlarged, non-painful lymph nodes.Ī lymph node affected by lymphoma will feel like a hard, rubbery lump under your dog’s skin. The most easily located lymph nodes on a dog’s body are the mandibular lymph nodes (under the jaw) and the popliteal lymph nodes (behind the knee). What are the most common symptoms of canine lymphoma? However, the link between immune suppression and lymphoma in dogs is not clearly established. Evidence for this includes increased rates of lymphoma in humans infected with the HIV virus or are on immune-suppressing drugs following organ transplantation surgery. Suppression of the immune system is a known risk factor for the development of lymphoma in humans. Although several possible causes such as viruses, bacteria, chemical exposure, and physical factors such as strong magnetic fields have been investigated, the cause of this cancer remains obscure. Unfortunately, the cause of lymphoma in dogs is not known. Other common lymphomas in dogs include cutaneous lymphoma (lymphoma of the skin), alimentary or gastrointestinal lymphoma (lymphoma of the stomach and/or intestines), and mediastinal lymphoma (lymphoma involving organs within the chest, such as lymph nodes or the thymus gland). Lymphocytes normally function as part of the immune system to protect the body from infection.Īlthough lymphoma can affect virtually any organ in the body, it most commonly arises in organs that function as part of the immune system such as the lymph nodes, spleen, and bone marrow.īy far the most common type of lymphoma in the dog is multicentric lymphoma, in which the cancer first becomes apparent in lymph nodes. The term “lymphoma” describes a diverse group of cancers in dogs that are derived from white blood cells called lymphocytes. I am so glad that they do." Frequently Asked Questions by Pet Owners What is lymphoma? We don't get to choose who occupies the spaces in our hearts, they (our dogs) just take residence, selfishly and without permission. "The Purdue University Small Animal Hospital was the perfect place for Harley to deal with his illness, and the doctors, students, and staff were of the highest caliber and the most gracious sentiment. Our goal is to improve the outlook for dogs and humans affected with this all too common cancer. It is our hope that research in canine lymphomas conducted by the Werling Comparative Oncology Research Center will discover new ways of treating NHL in both dogs and humans. And it is one of the few human cancers for which the frequency of newly diagnosed cases is still on the rise. In 2010, NHL was diagnosed in approximately 65,000 people in the United States, and claimed approximately 20,000 lives, making it the seventh most common cancer overall, and the sixth most common cause of cancer-related death. Canine lymphomas and NHL are nearly indistinguishable when examined microscopically, and both tumor types exhibit similar responses to chemotherapy. Lymphomas may affect any organ in the body, but most commonly originate in lymph nodes, before spreading to other organs such as the spleen, liver, and bone marrow.Ĭanine lymphomas are similar in many ways to the non-Hodgkin's lymphomas (NHL) which occur in humans. Some progress rapidly and are acutely life-threatening without treatment, while others progress very slowly and are managed as chronic, indolent diseases. There are over 30 described types of canine lymphoma, and these cancers vary tremendously in their behavior. They collectively represent approximately 7-14% of all cancers diagnosed in dogs.
