As far as China is concerned, the incidence of gastric cancer in the northwest and east is higher than that in the south, which may be related to local eating habits or living environment.
For the general public, the prevention of gastric cancer mainly lies in health education and health promotion in daily life, reasonable dietary nutrition and changing bad eating habits, which belongs to the category of "primary prevention", etiology prevention and gastric cancer prevention. Secondly, high-risk groups should have regular physical examinations and strive for early detection and early treatment, which is "secondary prevention". At present, the effective examination method is gastroscopy, which can find gastric lesions early and intervene in time.
This will damage the gastric mucosa, which will form in the long run. The doctor said that gastritis and gastric erosion, due to the long-term inability of mucosa to recover, induced mutation or mutation of Helicobacter pylori, coupled with the decline of human immune function, is the cause of gastric cancer.
Related research shows that the incidence of gastric cancer will increase significantly in patients over 40 years old, so it is suggested that patients over 40 years old should be routinely screened for gastroscopy.
Even various microorganisms will be killed by acidic gastric juice.
Helicobacter pylori is a parasitic bacterium left by human evolution and will not bring any harm. Not the culprit of gastric cancer.
Helicobacter pylori infection, who has determined that Helicobacter pylori is a carcinogen. Studies have shown that Helicobacter pylori can induce gastric cancer in mice. The toxin secreted by Helicobacter pylori is pathogenic, which will lead to gastric mucosal lesions, from superficial inflammation to atrophy and atypical hyperplasia, and will also catalyze nitrosation to cause cancer.
Therefore, experts remind that people with polyps, frequent stomach upset, family history of gastric cancer, gastric ulcer and atrophic gastritis should be treated as soon as possible to reduce the chance of developing gastric cancer.
