More common compared with oesophageal neoplasia but still uncommon accounting for less than 1% of all malignancies. Malignant tumours include:
- Adenocarcinoma
- Squamous Cell Carcinoma
- Lymphoma
- Fribrosarcoma
- Plasmacytoma
- Leiomyosarcoma
Benign tumours include:
- Polyps
- Leiomyoma
Signalment

Description
Aetiology largely idiopathic though long term ingestion of dietary carcinogens may have some responsibility. Long term administration of nitrosamines may cause carcinomas in dogs. In humans, the bacterium Helicobacter pylori can induce gastric carcinoma and lymphoma. Its role in gastric tumours in dogs and cats has not yet been fully established though it can cause gastritis and ulceration. Belgian Shepher dogs may have a genetic predisposition to gastric carcinoma. Cats with gastric lymphoma are not usually FeLV positive.
==Diagnosis== (based on typical history, clinical signs, physical exam findings, imaging/laboratory results)
