Stomach cancer is one of the common malignant tumors in my country, and its incidence rate is the first in China. Among the malignant tumors of the stomach, 95%of adenocarcinoma is also the most common digestive tract malignant tumor, and even before all human malignant tumors. Early gastric cancer is asymptomatic or only mild symptoms. When the clinical symptoms are obvious, the lesions are late. Therefore, we must be very alert to the early symptoms of gastric cancer to avoid delay and treatment.
Gastric cancer is a higher incidence among Oriental. The most serious of which is Japan. Gastric cancer is mainly related to diet. The first is to take too much salt, and the other is the lack of vitamin C.
Salt is essential in daily diet, and salt has the taste in the dishes. However, some people are used to putting more salt and like to eat heavy dishes. In addition to causing hypertension, the result of this can also cause gastric cancer. Doctors advice to long -term food with high salt is tantamount to chronic suicide.
Studies have found that excessive salt intake can damage the gastric mucosa barrier, increase the susceptibility to carcinogens, and lead to high incidence of gastric cancer. If the infection of spiral bacteria, the incidence of gastric cancer will increase sharply. Under the action of salt, Helicobacter pylori is more likely to release a carcinogenic substance. In order to prevent gastric cancer, people with Peroxibiotics in the gastrointestinal and intestines should eat low -salt food. There are both a large amount of salt in salted fish and pumpkin, as well as carcinogens such as nitrite. Therefore, people who eat more salted fish and cashmere people have a high chance of gastric cancer.
According to reports, gastric cancer is high, and vitamin C deficiency is also the culprit. Epidemiological studies have found that vitamin C is generally lacking in diet in Japanese residents. Because Japan is an island country, fresh fruits and vegetables are not eaten, which makes the intake of vitamin C low. Studies have found that vitamin C can block the synthesis of carcinogenic nitro compounds, thereby achieving the effect of preventing cancer. At present, the rich vitamin C has been written into a dietary guide for cancer prevention by multiple countries.
In view of the serious harm of gastric cancer to Japanese citizens, the National Cancer Center of Japan has proposed 8 suggestions for diet preventing gastric cancer: 1. Balanced nutrition; 2. Daily daily daily changes; 3. . Eat more green and yellow vegetables; 6. Eat less salty foods; 7. Do not eat the food of food; 8. Before eating, see if the food is moldy.
The reporter learned that in the past 40 years, the mortality rate of gastric cancer in Japan has fallen by half. The main reason is that people over the age of 40 generally check gastroscopy every year, actively treat gastric pylori, so that gastric cancer can be discovered early and the survival rate is improved.
