Breed incidence of lymphoma in a UK population of insured dogs.
Canine lymphoma is one of the commonest forms of spontaneous canine neoplasia. Improved understanding of the genetic and environmental risk factors for canine lymphoma, including breed differences, may have comparative benefits for the study of non-Hodgkin's lymphoma in humans. In this study, data from a pet insurance company were used to estimate the incidences of canine lymphoma for pedigree breeds in the UK. Out of a total of 130,684 insured dogs, 103 had a diagnosis of lymphoma recorded. A significant breed effect was found with the boxer, bulldog and bull mastiff breeds, all having a high incidence of lymphoma. The small number of lymphoma cases recorded may have limited our ability to detect other breeds with an elevated risk. Incidence of lymphoma was found to increase with age, peaking at 10 years of age.
