What is the relationship between gastric ulcer and gastric cancer What are the pathogenic factors of gastric cancer

1. Gastric ulcer and gastric cancer.

Gastric ulcer and gastric cancer are two completely different diseases, but there are many similarities in clinical manifestations, especially ulcerative gastric cancer, so it is easy to be misdiagnosed. But as long as careful observation, gastric ulcer and gastric cancer can still be distinguished. Gastric ulcer is more common in young adults, while gastric cancer is more common in middle-aged and elderly people. The symptoms of gastric ulcers are different from those of gastric cancer. 90% of gastric ulcers have epigastric pain, mainly half an hour after meals, which occurs periodically, which can be relieved after several hours, and can be relieved after eating or taking antacid drugs.


More than 70% of early gastric cancer has no obvious symptoms, with the development of the course, symptoms similar to gastritis or gastric ulcer can gradually appear, and will be progressive, the disease develops faster, and the course of disease is shorter. The pain is more irregular, and the pain is not relieved by eating or taking acidifiers. Of course, in order to further distinguish the two diseases, special examinations such as fecal occult blood test, X-ray barium meal, gastroscopy and so on are needed. In order not to delay the disease, try to achieve early detection and early treatment of cancer.


2. Pathogenic factors of gastric cancer.


The etiology of gastric cancer is very complex, which is a multi-step, multi-factor progressive development process. It is generally believed that the occurrence of gastric cancer is caused by the participation of the following factors.


Helicobacter pylori (Hp) infection:


It is the most clear and important risk factor for gastric cancer at present.

Diet and environmental factors:


The occurrence of gastric cancer is related to the region. In addition, the most direct is the bad habits in daily life. Long-term consumption of moldy food, pickled vegetables, smoking, pickling and high-salt food can increase the risk of gastric cancer and is the "culprit" of gastric cancer.
