1, high-salt diet.

High-salt diet will destroy the mucous protective layer of gastric mucosa, expose gastric mucosa to acidic gastric juice with bacteria, directly damage gastric mucosa, and greatly increase the chance of contact with carcinogens. On the other hand, nitrite can produce nitrosamines, a strong carcinogen, in the stomach. The damaged gastric mucosa is exposed to nitroamine, and the chance of canceration will increase.

2. The diet is too vegetarian.

Gastric mucosa is an important protective film in our body, but if it is stimulated and damaged for a long time, it will form an ulcer. Under normal circumstances, gastric mucosa can be repaired in 4 or 5 days, but only if there is enough protein. If you eat Tai Su and you don't have enough protein in your body, the repair of gastric mucosa will be blocked, and over time, a minor illness will be dragged into a serious illness.

3. Long-term iron deficiency anemia.

If iron deficiency anemia is not treated in time, iron in the body will be further deficient, thus inducing gastric cancer. Iron deficiency can easily lead to chronic atrophy of the mucosa of the tongue, esophagus, stomach and small intestine, so that gastric acid secretion is too little or lacking, and bacteria multiply in the stomach, providing opportunities for nitrate ingested in the body to combine with amines in the stomach to form nitrosamines, which are a strong carcinogen.

4. I ate dinner late.

Eating too late for dinner or eating supper often may increase the burden on the stomach, which will increase the risk of gastric cancer in the long run. Gastric acid reflux will not only bring discomfort such as heartburn, but also cause damage to esophagus. If the esophageal mucosa is stimulated by gastric acid for a long time, it may produce "atypical hyperplasia" and gradually develop into precancerous lesions.

Prevention of gastric cancer:

1, pay attention to scientific diet.

Low-salt and light diet, eat less pungent and sour food, drink less, eat on time, and avoid eating seafood and drinking. If this can be done, the incidence of gastritis and gastric ulcer will be greatly reduced.

2. Frozen fresh food.

Food preservation is through keeping it fresh in the refrigerator, not preventing it as before.

Food spoilage is preserved with a lot of salt, which reduces the generation of nitrosamines.

3. Pay attention to balanced nutrition.

Keep the recipes diversified. In addition, fresh vegetables and fruits rich in vitamin C have a protective effect on preventing gastric cancer, and vitamin A can effectively prevent and inhibit the proliferation and spread of cancer cells.

4. Actively treat gastric ulcer and atrophic gastritis.

For long-term unhealed gastric ulcer, severe atypical gastritis, multiple polyps or single polyps with a diameter greater than 2cm, surgical treatment can be taken.

5. Physical examination and screening.

Early detection is the key to prevent gastric cancer, and screening through general survey is an important measure. The conditions that can be investigated are those who are over 40 years old, have a long-term history of stomach problems, or have obvious stomach symptoms in recent months.
