What kind of disease is gastric cancer? What are the symptoms of gastric cancer?

Gastric cancer specifically refers to the epithelial tissue of the gastric mucosa in the stomach, which is transformed into cancer cells due to various reasons. After long-term stimulation and spread, the cancer cells gradually expand and penetrate the entire stomach wall. Although advanced gastric cancer can be cured, the mortality rate is also very high.

Gastric cancer is more common in men, and the incidence rate of men is twice that of women, because many of the causes of gastric cancer are caused by long-term smoking, drinking, or long-term exposure to harmful substances in the work environment. But what kind of disease is gastric cancer? Many people don't know, so let's learn about it together!
1. Gastric cancer <br/>Gastric cancer refers to the epithelial tissue of the gastric mucosa in the stomach, which is transformed into cancer cells due to various reasons. After long-term stimulation and spread, the cancer cells gradually expand and penetrate the entire stomach wall. After spreading, it will also occur in the greater and lesser curvatures of the stomach and the surrounding pancreas, forming gastric cancer.
2. Symptoms of Gastric Cancer
1. If you have gastric cancer, there will be many complications, such as gastrointestinal bleeding, because bleeding symptoms will appear in the early stage of gastric cancer, which is the first symptom of gastric cancer. If cancer cells erode larger blood vessels, or the blood vessels in the submucosal layer of the stomach are damaged, a large amount of vomiting blood and black stool will occur, which is also a complication of gastric cancer. And once the disease occurs, ordinary hemostatic drugs are not very effective for the symptoms of gastric cancer bleeding, and there is a high mortality rate.
2. During the onset of gastric cancer, there will be abdominal distension, loss of appetite, nausea, vomiting, and vomited food will have a foul smell. There will also be difficulty in swallowing, and in severe cases, even eating liquid food will feel obstructed.
3. Gastric perforation. If gastric cancer occurs, cancer cells will erode the gastric membrane tissue, causing inflammation, and irritating symptoms such as abdominal muscle stiffness and abdominal tenderness will appear.
4. During the spread of gastric cancer, the pathogenic cells may erode the common bile duct, or the common bile duct may be enlarged by swollen lymph nodes, which may cause the stool to become clay-colored and may also cause constipation.
3. Causes of Gastric Cancer <br/>If you often eat foods that contain a lot of carcinogens, such as barbecue, salted foods, leftovers, etc., it is very likely to cause gastric cancer in the long run. In addition, cancer may also be stimulated by chronic gastritis.
