What are the causes of gastric cancer

summary

Gastric cancer disease is still relatively common in life, and there are many reasons for gastric cancer disease. After suffering from gastric cancer, the most important thing is that the psychological attack on patients is very serious, which also seriously plagues the lives of patients. What are the causes of this complex and terrible disease? Let's see the following knowledge to understand it

What are the causes of gastric cancer

1. Environmental factors are closely related to the occurrence of gastric cancer. Japan is a country with high incidence of gastric cancer. The incidence rate of gastric cancer descended obviously in Japan when it immigrated to the United States. It is generally believed that the incidence rate of residents in cold wet area, peat soil and asbestos area is high. Some people think that the imbalance of some chemical elements and trace elements is related to the occurrence of gastric cancer.

2. Living and eating habits. According to the worldwide epidemiological data, diet is the main cause of gastric cancer. Through a large number of people's retrospective investigation and analysis of many factors, it is found that gastric cancer is closely related to eating more pickled vegetables, salted fish, salted meat and smoked food. On the contrary, milk, fresh vegetables, fruits, vitamin C and refrigerated food can reduce the risk of gastric cancer. Excessive intake of salt electricity may be related to the incidence of gastric cancer. The carcinogen of gastric cancer may be nitrosamines. Animal experiments have proved that the substance can cause gastric cancer. Nitrite is reduced from nitrate to nitrite and then combined with amine. Nitrate and sulfite widely exist in food, especially in pickled vegetables, salted fish, salted meat and so on. High concentration of nitrite was also found in gastric juice of some patients. Reducing salt intake is often accompanied by a decrease in nitrate and nitrite intake. Low temperature can inhibit the transformation of nitrate to nitrite. In recent years, the incidence rate of gastric cancer in the United States and Japan has been decreasing. The widespread use of refrigerators may be a factor. Vitamin C can inhibit the combination of nitrite and amine, so regular use of vitamin C can reduce the risk of gastric cancer.

3. Nitrosamines. Although nitrosamines do not exist much in nature, the precursors of nitrosamines, secondary amines and nitrites, are widely distributed in nature. There are many opportunities for human contact with nitrosamines, and nitrosamines are easily synthesized under the action of appropriate acidity (ph1-ph3) or bacteria. Therefore, nitrosamines are considered to be the main cause of human gastric cancer.

matters needing attention
