What are the symptoms of stomach cancer?

What are the common symptoms of gastric cancer? Gastric cancer is one of the most common malignant tumors, and its incidence rate ranks first in my country. According to statistics, about 170,000 people die from gastric cancer every year, which is almost 1/4 of all deaths from malignant tumors. In addition, more than 20,000 new gastric cancer patients are generated every year. Gastric cancer is indeed a disease that seriously threatens people's health.

The symptoms and signs of gastric cancer vary depending on the location, type, size of the tumor, the course of the disease, the presence or absence of complications or metastases, etc. Most patients may have no symptoms in the early stages of the disease.

1. The pain of stomachache is mainly in the pit of the stomach, and sometimes it is only upper abdominal discomfort or dull pain. The more typical pain is irregular and is not relieved by eating.

2. Loss of appetite

3. Nausea and vomiting. Since most gastric cancers are located in the pyloric antrum, pyloric obstruction symptoms are quite common. Atypical early obstruction can cause a feeling of bloating after eating, mild nausea, and regurgitation, while typical mechanical pyloric obstruction causes gastric distension and vomiting. Vomitus is mostly food that has stayed in the stomach for too long, so it has a sour and rancid smell. Diffuse gastric cancer often does not have symptoms of obstruction and vomiting.
