What factors can lead to gastric cancer

The cause of gastric cancer is still unclear. It is generally believed to be related to the patient's age, gender and genetics. Some chronic benign gastric diseases, such as gastric polyps, gastric ulcers, chronic atrophic gastritis and pernicious anemia, may also develop into gastric cancer. In addition, food spoilage or improper cooking, geographical conditions, air, water sources, environmental pollution, dust and poison exposure are also related to the occurrence of gastric cancer.

Various studies have shown that there is a direct relationship between gastric cancer and eating habits. Gastric cancer is common in Japan, but the third generation of Japanese immigrants to the United States has a gastric cancer rate that is on par with that of local Americans, which shows that gastric cancer is closely related to diet and living environment. Salted foods, pickled foods, and moldy foods are all considered risk factors for gastric cancer.
