Stomach cancer is a malignant tumor that occurs in the stomach, the incidence is very high, and it shows an upward trend year by year. In 2020 alone, the number of new people with stomach cancer in China reached 480,000, while the number of deaths reached 370,000, which is a malignant disease that seriously threatens human health and life.
Therefore, in daily life, we must do a good job in preventing stomach cancer, especially the probability of stomach cancer in the following categories of people is many times higher than that of other groups.
The following is a detailed introduction for everyone, hoping to arouse the high vigilance of these groups.
Which groups are at high risk of stomach cancer?
1. People who have suffered from chronic stomach diseases for a long time
The causes of stomach cancer are complex, but if you have chronic stomach disease for a long time, the probability of developing stomach cancer will be particularly high.
For example, for people with chronic gastritis for a long time, although chronic gastritis is a particularly common benign disease, if it is not treated in time, or if it is not done well in daily nursing work, it will lead to long-term stimulation of inflammation of the gastric mucosa, and it is easy to cause the emergence of atrophic gastritis.
Once atrophic gastritis is developed, it will be accompanied by a series of lesions such as intestinal metaplasia and dysplasia. The damaged surface of the gastric mucosa will become larger and larger, and the cells of the mucosa will change in the process of continuous repair, resulting in the emergence of gastric cancer.
In addition, if infected with Helicobacter pylori, this bacterium will survive in the gastric mucosa and release some toxicity, resulting in corresponding stimulation of the gastric mucosa, causing inflammation and ulceration of the gastric mucosa. If it continues to develop, it will turn into stomach cancer at a later stage.
Second, long-term drinking and smoking people
Long-term smoking and drinking is one of the main triggers for stomach cancer. The probability of stomach cancer in smokers is 4 to 6 times higher than that of non-smokers.
Various carcinogens contained in cigarettes will enter the stomach with the digestive tract, so that the gastric mucosa will be stimulated and lead to abnormal spasm of blood vessels, and the mucous membrane will appear more obvious ischemia and hypoxia. Over time, a series of chronic stomach lesions can be induced.
If you drink alcohol for a long time, the immune barrier of the gastric mucosa will be destroyed, resulting in hyperemia, edema, and even erosion and bleeding of the gastric mucosa. It will form a stomach ulcer phenomenon, and it is easy to develop stomach cancer in the later stage.
Third, long-term diet of the wrong people
Long-term dietary errors are one of the most important factors that induce stomach cancer, such as eating some pickled foods in daily life, such as smoked fish, bacon, and pickled vegetables. After the nitrite components contained in these foods enter the human body, it is easy to form the carcinogen nitrosamine.
If large-scale intake is taken for a long time, the probability of stomach cancer will naturally increase relatively. In addition, if you particularly like to eat some overheated foods or spicy stimulating foods, and there is no regularity in three meals a day, it will also lead to abnormal hyperplasia of the gastric mucosa, which will develop into stomach cancer.
Fourth, people with negative emotions for a long time
The stomach belongs to an emotional organ, and all activities are regulated by the autonomic nervous system. If you are in negative emotions for a long time, such as anxiety, sulking, anger and other bad emotions, it will affect the normal function of the emotional central nervous system.
The autonomic nerves that regulate the gastrointestinal tract will have dysfunctional phenomena, which will affect the normal secretion of gastric juice, which will make people have reduced appetite and easy stomach pain. Over time, the probability of suffering from a series of stomach diseases and stomach cancer naturally increases.
All in all, the above 4 groups of people belong to the high incidence of stomach cancer. Therefore, if you want to avoid stomach cancer, you must avoid the above undesirable factors.
In addition, we must pay attention to doing a good job of keeping the body warm. Once the body is cold for a long time, the stomach will also have abnormal spasms, which will affect the normal function of the stomach, and the probability of various stomach diseases will also increase.
If indigestion, stomach pain, anorexia, blood in the stool or melena occur repeatedly in daily life, you must be admitted to the hospital for examination and receive formal treatment at the first time to maximize the maintenance of your health.
