Stomach Cancer: Overview
About the stomach
The stomach is located in the upper abdomen and plays a central role in digesting food. When food is swallowed, it is pushed down the muscular tube that connects the throat with the stomach called the esophagus and enters the stomach. The muscles in the stomach mix the food and release gastric juices that help break down and digest the food. The food then moves into the small intestine for further digestion.
Types of stomach cancer
Stomach cancer, also called gastric cancer, begins when cells in the stomach become abnormal and grow uncontrollably. A tumor can be cancerous or benign. A cancerous tumor is malignant, meaning it can spread to other parts of the body. A benign tumor means the tumor will not spread. Cancer can begin in any part of the stomach, and it can spread to nearby lymph nodes and other areas of the body, such as the liver, bones, lungs, and a woman’s ovaries.
Most stomach cancers are a type called adenocarcinoma, which means that the cancer started in the glandular tissue that lines the inside of the stomach. Other types of cancerous tumors that form in the stomach include lymphoma, gastric sarcoma, and carcinoid tumors, but these are rare.
