How do dogs develop lymphoma. Dogs with multicentric lymphoma may also develop lethargy fever anorexia weakness and dehydration as the disease progresses. Dogs with alimentary lymphoma. Lymphoma is a cancer of the lymph nodes and lymphatic system.
This cancer may be localized to one particular region or may spread throughout the entire body. Lymphoma is a relatively common cancer accounting for 15-20 of new cancer diagnoses in dogs. The prognosis for lymphoma varies depending on various characteristics that can only be determined by specialized testing.
Almost all lymphoma found in dogs is multicentric making up approximately 85 or all lymphoma cases found in dogs are multicentric. Multicentric lymphoma affects the lymph nodes when cancer is in the lymph nodes it causes excessive swelling and enlargement of the lymph nodes.

It is a progressive deadly disease caused by the harmful growth of lymphocytes. Lymphoma most commonly arises from lymphoid tissues in the bone marrow thymus lymph nodes or spleen. Other common sites include the skin eye central nervous system and bone.
Causes of Dog Lymphoma Lymphoma develops as a result of a series of genetic mutations in a lymphocyte. A lymphocyte or lymphocytes are white blood cells that fight off infections. When lymphocytes mutate abnormally they ultimately become malignant cells which subsequently affect body organs and functions.
Canine Multicentric Lymphoma Lymphoma is a cancer of the cells of the immune system called lymphocytes. Lymphocytes are present throughout the body so dogs can develop lymphoma in multiple organs. Lymphoma most often affects lymph nodes but can also affect the liver spleen bone marrow and other sites.
Among the most common types of cancer in dogs canine lymphoma exists in more than 30 forms that behave differently.
