What are the symptoms of stomach cancer?

Gastric cancer is the most common gastric tumor, a malignant tumor of the epithelium, namely gastric adenocarcinoma. Adenocarcinoma accounts for 95% of gastric malignant tumors. It is also the most common digestive tract malignancy, and even the leader among all human malignant tumors. It is more common in men after middle age. In recent years, with the development of modern life, gastric cancer has shown a trend of younger age, which is closely related to bad living habits and environmental pollution.

1. More than 80% of patients experience upper abdominal pain.

2. About one-third of patients experience bloating, upper abdominal discomfort, loss of appetite, indigestion, and heartburn.

3. Although one-third of patients do not have obvious digestive system symptoms, they may experience unexplained weight loss, emaciation and fatigue.

4. Some patients experience symptoms such as heartburn, nausea, vomiting, hiccups or black stools.

Indigestion symptoms such as loss of appetite, anorexia, nausea and vomiting, bloating after eating, hiccups, and acid reflux are also a group of common and non-specific early gastric cancer symptoms. Loss of appetite may be an early symptom of gastric cancer without stomach pain. If it occurs at the same time as stomach pain symptoms, hepatitis can be ruled out, so pay special attention. Some patients automatically restrict their daily diet due to bloating and hiccups after eating, resulting in weight loss, emaciation, and fatigue. Early symptoms of gastric cancer may also include a feeling of fullness after eating and mild nausea.
