Incidence of canine mammary carcinoma

The present investigation aimed to determine the incidence of canine mammary carcinoma in dogs presented to veterinary hospitals. Out of a total of 42, 505 dogs examined, 422 cases were diagnosed with malignant neoplasms, indicating an overall incidence rate of 0.99%. Canine mammary carcinoma was most frequently observed in dogs aged between 6 and 10 years (66.67%), while the lowest incidence was recorded in the 0 to 5-year age group (7.41%). Among the affected breeds, Labrador Retrievers exhibited the highest breed-specific incidence at 38.28%, with a marked prevalence in intact female dogs (88.89%).
