8) Fluid Build-up in the Abdomen
Cancer that develops in the stomach almost invariably produces a feeling of swelling in the abdomen as well as alters gastrointestinal function. But beyond that, it is possible that stomach cancer causes a condition known as ascites.
Ascites is defined as the presence of fluid in the peritoneal cavity and is typically observed in various pathologies, mainly in hepatic and oncological diseases. In general, unless the accumulation of fluid in the abdomen is significant, there are no symptoms besides slight abdominal distension, heartburn, indigestion, and pain in the lower back.
