Canine Lymphoma

Jul 26, 2018

Lymphoma and lymphosarcoma (LSA) are interchangeable terms. Lymphoma in dogs is very similar to non-Hodgkin's lymphoma in people. Lymphoma represents 7% of all cancers in dogs. Most affected dogs are between 5-9 years of age, but the disease can occur in dogs of any age. Generalized lymphadenopathy (lymph node enlargement) in an otherwise healthy dog is the most common presentation. Hypercalcemia (high blood calcium) occurs in 20% of dogs with lymphoma. Administration of glucocorticoids (steroids) prior to confirming a diagnosis can make obtaining the diagnosis much more difficult and lead to the cancer becoming chemotherapy resistant.
