Cancer is an abnormal or malignant growth in a body cell. This is known as stomach cancer or gastric cancer. It is caused by the growth of cancerous cells in the stomach. To understand this type of cancer better, let's look at the stomach. The stomach is made of three tissue layers which are mucosal, muscular, and serosal which are the innermost, middle, and outermost layers respectively.

Gastric adenocarcinoma, also known as glandular tissue cancer, is one of the most common types of stomach cancer. Other forms of stomach cancer are rare, such as lymphomas (cancer that affects the lymphatic system) and sarcomas (cancer that affects connective tissue like fat and blood vessels).
The one thing that can cause stomach cancer or other forms of cancer is the possibility it could affect nearby lymph nodes. It could spread from the stomach to nearby tissues, such as the pancreas, intestine and esophagus. It can also spread to other vital organs such as the liver and lungs.
Some stomach tumors have spread through the lymphatic system, affecting all lymph nodes. When stomach cancer spreads in this manner, it creates the cancerous cells from its source and not its destination.
