Stomach cancer (also called gastric cancer) can develop in any part of the stomach, and may spread throughout the stomach and to other organs. It may grow along the stomach wall into the esophagus or small intestine.
The cancer may extend through the stomach wall and spread to nearby lymph nodes and organs such as the liver, pancreas, and colon; or spread to distant organs, such as the lungs, the lymph nodes above the collarbone, and to the ovaries.
Stomach cancer types include:
- Gastrointestinal stromal tumors, or GISTs
- Carcinoid tumors
