Gastric cancer is a malignant tumor originating from the epithelium of gastric mucosa, accounting for 95% of gastric malignant tumors, and its proportion in human tumors varies with different regions, generally about 10-30%, which shows that gastric cancer is a common disease threatening human health.
Etiology.
The exact cause is unclear at present, and it is generally believed that external environmental and dietary factors are most closely related to the occurrence of gastric cancer. It is worth noting the high-risk groups of gastric cancer: people over 50 years old with chronic gastric ulcer, chronic atrophic gastritis, gastric polyps, especially those with moderate or above atypical hyperplasia and intestinal adenosis in gastric mucosa, are highly susceptible to cancer. The cancer rate of atrophic gastritis is reported to be 6-10%, that of gastric ulcer is 1.96%, and that of gastric polyp is about 5%. It has also been reported that patients with pernicious anemia have a 5 times higher chance of developing gastric cancer than the general population.
Common symptoms.
1.Stomach pain: the most common, but not specific.
2.Loss of appetite, emaciation and weakness: common, non-specific, but sometimes can be the first.
3, nausea and vomiting: due to gastrointestinal flocculation or obstruction.
4.Bleeding and black stool.
5, Other symptoms: diarrhea, constipation, fever, etc.
How to diagnose.
Once symptoms such as continuous pain in upper abdomen of unknown origin, loss of appetite, emaciation, black stool, anemia, vomiting blood, etc. occur, you should go to hospital for examination as soon as possible. The above symptoms, or suspicion of gastric cancer, should promptly go to the hospital for gastroscopy or barium meal examination of digestive tract
Treatment.
Once the diagnosis of gastric cancer is confirmed, surgery should be strived for as early as possible, and after surgery, chemotherapy, Chinese herbal medicine, immunization and other comprehensive treatments should be carried out according to the condition in order to improve the cure rate. The five-year survival rate of early gastric cancer surgical resection can reach more than 95%, so the key to improve the efficacy is early detection, early diagnosis and early treatment.
Eight measures for prevention.
1.Eat less or do not eat pickled vegetables.
2. Do not eat smoked or fried food.
3, do not eat moldy food.
4.Do not smoke and drink less alcohol.
5, to develop good eating habits.
6.Eat more fresh vegetables and fruits.
7.Protect the hygiene of consuming water.
8.Actively treat precancerous lesions. For people suffering from atrophic gastritis, gastric ulcer, gastric polyadenomatous polyp, pernicious anemia, they should visit the hospital for gastroscopy and treatment once every 3 to 6 months frequently.
