Splenic Tumours (Non-Hemangiosarcoma) in Dogs
Splenic Tumours (Non-Hemangiosarcoma) is a high-severity cancer condition that can affect dogs of all ages and breeds. The spleen is a common site for tumours in dogs. Nodular hyperplasia (benign) and haematomas account for approximately two-thirds of splenic masses; haemangiosarcoma makes up most malignant cases. All require histopathological diagnosis after splenectomy. It is documented across 4 breeds, though prevalence and severity can differ significantly between them. It typically becomes apparent at 8-13 years. Early signs to watch for include asymptomatic in early disease, abdominal mass, sudden collapse from splenic rupture, and pale gums. When treatment is required, costs are estimated at £2,000-£8,000 depending on severity, location, and the specific intervention needed. This page covers symptoms, treatment options, and preventive steps — along with breed-specific information where available.
