Stomach cancer is often referred to as gastric cancer. It includes cancer that starts to grow in the lining of the stomach. A similar type of cancer is gastroesophageal junction cancer (also known as GE Junction or GEJ). This is cancer that starts to grow in the place where the esophagus and the stomach meet. Metastatic means that the cancer has spread to other parts of the body. While it is less common in the United States, stomach cancer is the fifth most common cancer in the world.
