The stomach is like a bag lined with muscle and glandular cells, and is the first place chewed food goes to after it has been chewed and swallowed. It produces acidic juices from its lining to start off the digestive process.
The vast majority of stomach cancers arise from this glandular lining of the stomach and are called adenocarcinomas. There are two broad types of stomach cancer: an intestinal type and a diffuse type. The former are like the usual adenocarcinomas found in the gut, whereas the latter have a very different appearance.
