1. What is the reason for the high incidence of gastric cancer?
The incidence of cancer in China is on the rise, which is related to many factors. Explain it briefly.
1, dietary factors:
China's diet is dominated by traditional diets such as high salt, pickling, smoking and baking. These foods often contain carcinogens such as nitrosamines, and long-term consumption will increase the probability of developing gastric cancer.
Long-term consumption of high-salt food will destroy gastric mucosa and increase the risk of inflammation and cancer. In addition, nitrite in pickled food may exceed the standard, and it will be metabolized into a strong carcinogen nitrosamine after entering the body.
It is no coincidence that China, Japan and South Korea, which have a high incidence of gastric cancer, have a long tradition of eating high-salt food and preserved food.
At the same time, bad habits such as irregular diet, skipping breakfast and overeating are also risk factors for gastric cancer.
2. Infection factors:
Helicobacter pylori infection is the most important risk factor for gastric cancer. Long-term infection with Helicobacter pylori may lead to chronic gastritis and stimulate cell variation and growth. In the long run, it will increase the risk of cancer. If you live in a high incidence area of gastric cancer and don't pay attention to eating separately, the risk of gastric cancer will increase.
It is estimated that more than 50% people in China are Helicobacter pylori carriers! The total number exceeds 700 million!
3. Habitual factors:
Smoking, drinking, obesity, laziness, lethargy, overeating and other bad habits are also risk factors for gastric cancer.
4. Genetic factors:
Carrying specific gene mutations, such as CDH 1. There is a kind of gastric cancer called "hereditary diffuse gastric cancer". Caused by CDH 1 mutation. People who carry this mutation have a probability of developing gastric cancer over 70% in their lifetime and may get sick when they are young.
The proportion of patients caused by genetic factors is very low, and the incidence of gastric cancer in China is high, which is mainly caused by external factors, including living habits and external environment.
Second, can stomach cancer cause stomach pain?
Not necessarily. Only 30%-40% of patients show epigastric pain in the early stage.
3. What are the symptoms of gastric cancer?
Early gastric cancer has no obvious discomfort symptoms, and individuals often have symptoms such as indigestion, early satiety, weight loss, dysphagia and melena.
Fourth, methods to prevent gastric cancer.
Change the diet structure: Try to eat fresh food, such as vegetables, fruits, beans and milk, fresh fish, meat and eggs. Pickled food is not completely inedible, but you must eat less.
Change bad eating habits: avoid overeating and irregular eating; Don't eat too fast, too hot or too hard; Eat less smoked and pickled food and avoid high-salt diet; Drink less and don't smoke.
Cleanliness: pay attention to healthy diet and don't eat moldy food; Protect the hygiene of drinking water; Wash your hands thoroughly with soap; Use public chopsticks when eating, and try to implement a separate meal system; Tableware is often disinfected.
Regular physical examination: Gastropathy includes gastric polyp, gastric ulcer, chronic atrophic gastritis, remnant stomach after partial gastrectomy, etc. These diseases may be accompanied by different degrees of chronic inflammatory process, intestinal metaplasia or atypical hyperplasia of gastric mucosa, and may turn into cancer. Regular physical examination, early detection and early treatment.
Prevention and treatment of stomach diseases: actively treat gastric ulcer and chronic gastritis, and treat helicobacter pylori infection in the stomach, especially patients with the above symptoms, which need to be examined in time. The items that must be checked include helicobacter pylori examination and gastroscopy.
