It's part of the digestive system. Food moves from the mouth through the esophagus to the stomach. In the stomach, the food becomes liquid. Muscles in the stomach wall push the liquid into the small intestine.
The wall of the stomach 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.
- Muscle layer: Muscles in this layer contract to mix and mash the food.
- Subserosa: This is the support tissue for the outer layer.
- Outer layer (serosa): The outer layer covers the stomach. It holds the stomach in place.
Cancer begins in cells, the building blocks that make up tissues. Tissues make up the stomach and other organs of the body.
Normal cells grow and divide to form new cells as the body needs them. When normal cells grow old or get damaged, they die, and new cells take their place - Stomach Cancer Surgeon in Udaipur.

The cancer cells may be found in lymph nodes near the stomach. The cancer cells may attach to other tissues and grow to form new tumors that may damage those tissues.
The spread of cancer is called metastasis.
