Adenocarcinoma – 

They are type of tumors most often associated with cancer of the stomach. This GI Tract cancer in dogs is one that is found in glandular tissue. It accounts for 70-80% of all malignancies. This type of cancer originates in the stomach wall and spreads to the gastric lymph nodes, omentum (fat on the bottom edge of the stomach), liver, oesophagus, adrenal glands, lungs, duodenum (first part of the intestine), pancreas and spleen. In some bizarre cases, gastric carcinoma is believed to have metastasized to the testes. Gastrointestinal stromal tumors (GIST) also account for 20% of all gastric tumors.

Adenocarcinoma can affect all breeds equally, it is a very challenging tumor to diagnose and treat. The median survival in gastric adenocarcinoma is 2 months.
