In recent years, the incidence of stomach cancer has been very high, and in 2020 alone, the number of new cases of stomach cancer in China reached 480,000, and the number of deaths was 370,000, which is a vicious disease that seriously threatens human health and life.
Especially for men aged 40 to 70, the probability of stomach cancer is very high. So there are many people who want to know why more and more people are suffering from stomach cancer.
Below, I will introduce it in detail for everyone, hoping to arouse the vigilance of all groups of people.
What are the reasons for the high incidence of stomach cancer?
First, dietary factors
One of the main reasons for the high incidence of stomach cancer is related to dietary factors. For most modern people, they especially like to eat some heavy foods, especially vegetables, eggs, meat or fish marinated in salt, as well as various types of smoked foods. These foods contain a lot of salt, and once too much salt is ingested, it will lead to a decrease in the viscosity of mucus in the stomach, which has a great protective effect on the stomach wall.
Once the viscosity is too low, it will make the protective effect of the gastric wall decline rapidly, resulting in damage to the mucous membrane of the gastric wall, which can easily cause a series of lesions.
In addition, if there are some bad eating habits for a long time, such as irregular meals three times a day, overeating, or dieting too much, like eating some overheated foods, it will lead to serious damage to the gastric mucosa.
The gastric mucosa will be in the process of self-repair, it is very likely that abnormal hyperplasia will occur, resulting in the emergence of stomach cancer.
Second, infectious factors
Long-term infection with bacteria is one of the main causes of stomach cancer, such as Helicobacter pylori infection. This is a bacterium that survives for a long time in the stomach and multiplies vigorously, and once infected, this bacterium will penetrate the mucus layer, settle on the surface of the gastric epithelial cells, and release some toxic factors that will cause serious damage to the stomach epithelial cells.
Moreover, it will release various types of inflammatory cells and inflammatory mediators, resulting in a rapid decline in the immune barrier of the stomach wall, which will induce the emergence of chronic gastritis, gastric ulcers and gastric cancer. Especially for people who have long liked to eat raw and cold foods and have not done a good job of dietary hygiene, the probability of infection with this bacterium will be particularly high.
Third, tobacco and alcohol factors
In cigarettes contained in tar, nicotine, carbon monoxide and other toxic and harmful substances, these substances will enter the stomach with the digestive tract, so that the stomach is stimulated, thereby secreting a large amount of stomach acid.
The gastric mucosa will be damaged by these acidic substances for a long time, which will cause a series of stomach lesions.
The ethanol substance in the alcohol will cause direct damage to the gastric mucosa, resulting in thinning of the gastric mucosa, and even a rupture phenomenon, and the risk of gastric cancer will naturally increase.
Fourth, disease factors
If a series of chronic stomach diseases are not treated early for a long time, the probability of stomach cancer will also increase relatively.
For example, after a long-term chronic gastritis, if it is not treated early, it will develop atrophic gastritis, and a series of lesions such as intestinal metaplasia and dysplasia will occur, and the risk of developing gastric cancer in the later stage will be relatively increased.
All in all, the reason for the increasing incidence of stomach cancer is related to the above 4 factors. In addition, if you are in negative emotions for a long time, it will also affect all activities of the stomach, thereby increasing the risk of stomach cancer. Therefore, if you want to prevent stomach cancer, you must avoid the above factors. Especially for people with some chronic stomach diseases, it is necessary to receive regular treatment and regular screening. Once precancerous lesions are found, treatment is given early to avoid stomach cancer to the greatest extent.
