Gastric cancer is a malignant tumor originating from the gastric mucosal epithelium. It is often related to high work stress, poor emotional state, and Helicobacter pylori infection.

It commonly occurs in people over 40 years old, and men are more affected than women.

It often manifests as upper abdominal discomfort, pain without obvious regularity, nausea, vomiting, and loss of appetite. The use of drugs for treating gastritis is not very effective.

As the disease progresses, symptoms such as fatigue, upper gastrointestinal bleeding, anemia, and weight loss may appear.

Once the above symptoms occur, a gastroscopy can confirm the diagnosis, achieving early diagnosis and early treatment.
