Stomach Cancer
Stomach cancer, also known as gastric cancer, arises from cells in the stomach.
There are several types of stomach cancer. Nearly all are gastric adenocarcinomas, which form from cells in the innermost layer of the stomach that produce mucus. Gastroesophageal junction adenocarcinoma forms where the stomach meets the esophagus and may be treated like gastric cancer or esophageal cancer.
Other types of cancer that can occur in the stomach are not typically treated like gastric cancer. They include gastrointestinal neuroendocrine tumors, gastrointestinal stromal tumors, and primary gastric lymphoma.
An estimated 26,890 new cases of stomach cancer will be diagnosed in the United States in 2024, and 10,880 people are expected to die from the disease, according to the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) Program. People with stomach cancer are 36.4% as likely to survive for five years after receiving a diagnosis as people in the general population. Chronic infection with H. pylori, a family history of stomach cancer, and other stomach diseases are some of the risk factors for developing stomach cancer.
