Stomach Cancer

The stomach

The stomach is a hole in the upper abdomen , under the ribs organ.

It is part of the digestive system. The food passes from the mouth through the esophagus to the stomach. In the stomach , the food becomes liquid . The muscles of the stomach wall pushes the fluid in the small intestine .
The stomach wall has five layers :

Inner layer or lining ( mucosa) : Juices made ​​by glands in the inner layer help digest food . Most stomach cancers begin in this layer.

Submucosa : This is the support tissue for the inner layer .
