What are the early symptoms of gastric cancer

The early symptoms of gastric cancer are varied and lack specificity, and can easily be confused with other gastric diseases. They include indigestion, upper abdominal pain, loss of appetite, weight loss, and anemia.

1. Indigestion

Patients may experience discomfort such as bloating, abdominal distension, nausea and vomiting, which are closely related to delayed gastric emptying caused by gastric tumors.

2. Upper abdominal pain

Patients with early gastric cancer often experience dull pain in the upper abdomen. The pain may occur after meals, and may be mild or severe at times, and is easily ignored.

3. Loss of appetite

Patients may lose interest in food and have a significant decrease in appetite, which may be related to the fact that gastric tumors affect the digestion and absorption of food.

4. Weight loss and anemia

As the disease progresses, patients may experience unexplained weight loss and emaciation, as well as symptoms of anemia such as weakness, fatigue, and shortness of breath. This is because gastric cancer affects appetite and causes chronic bleeding in the gastric mucosa.

Although the early symptoms of gastric cancer are not specific, they should be taken seriously. When the above symptoms appear, you should seek medical attention for professional examination in time to detect, diagnose and treat gastric cancer at an early stage.
