Stomach Cancer vs. Stomach Ulcers - Differences in Symptoms and Signs Topic Guide

Stomach Cancer vs. Stomach Ulcers (Differences in Symptoms and Signs) Stomach Cancer vs. Stomach Ulcers (Differences in Symptoms and Signs): Stomach (gastric) cancer and peptic or stomach ulcers (duodenal and gastric) are diseases of the gastrointestinal (GI, digestive) tract, and both can be caused by Helicobacter pylori (H. pylori) infection.

Usually, there are no distinct early warning signs and symptoms of stomach cancer or stomach ulcers. When symptoms and signs of gastric or duodenal ulcers do occur, usually, they are milder than those from stomach cancer. Stomach cancer often is not diagnosed until the later stages because usually, it causes no early symptoms. Symptoms and signs of advanced stomach cancer include fatigue, weight loss, anemia, black tarry stools, and severe nausea and vomiting, sometimes with blood. Stomach ulcer symptoms and signs include mild digestion, stomach discomfort, hunger pain, or abdominal burning a couple of hours after eating.

Gastric and duodenal ulcers can cause gastrointestinal bleeding, but it does not occur until the ulcer ruptures. Duodenal ulcers are benign (noncancerous), and rarely, gastric ulcers can cause stomach cancer.
