Every Tumour Counts: A Comprehensive Overview of Canine Oncology in Portugal.

ABSTRACT: Robust nationwide data on canine oncology in Portugal are scarce. We retrospectively reviewed 17,773 biopsy submissions received by a nationwide veterinary laboratory (2020-2024). After applying inclusion criteria, 6359 histopathology-confirmed tumours were analysed by behaviour, anatomical site, and host/geographical factors. Malignant and benign neoplasms occurred in near-equal proportions (50.4% vs. 49.6%). Tumour distribution was dominated by cutaneous/soft tissues (58.8%) and the mammary gland (24.1%), with all other sites individually rare. Dogs with malignant tumours were older than those with benign lesions (p < 0.001), and age differed by tumour behaviour and sex in two-way ANOVA (both p ≤ 0.001). Females accounted for 58.7% of submissions, and malignant disease was
