1. Gastric cancer

The specific meaning of gastric cancer refers to the epithelial tissue of the gastric mucosa, 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 curvature of the stomach, the lesser curvature of the stomach and the surrounding pancreas, forming gastric cancer. If you often eat foods that contain a lot of carcinogens, such as barbecue, salted foods, leftovers, etc., it is likely to cause gastric cancer in the long run. Cancer may also be caused by chronic gastritis.

2. Symptoms of Gastric Cancer

1. Gastrointestinal bleeding: If you have gastric cancer, there will be various complications, such as gastrointestinal bleeding symptoms, because of the early bleeding of gastric cancer, which is the primary symptom of gastric cancer. If cancer cells erode larger blood vessels, or the blood vessels under the gastric mucosa 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, the usual hemostatic drugs have little effect on the symptoms of gastric cancer bleeding.

2. Abdominal distension and vomiting: During the onset of gastric cancer, abdominal distension, loss of appetite, nausea and vomiting will occur, and the vomited food will have a strange smell. In addition, swallowing difficulties will occur, and in severe cases, even eating liquid food will feel obstructed.

3. Gastric perforation: If gastric cancer occurs, cancer cells will erode the gastric mucosal tissue, causing inflammation, and irritating symptoms such as abdominal muscle stiffness and abdominal pain will appear.

4. Swollen lymph nodes: During the spread of gastric cancer, diseased cells may erode the common bile duct or cause swollen lymph nodes, resulting in clay-colored stools and possibly constipation.
