With the rapid development of science and technology, medical technology is improving day by day, and many “incurable diseases” have been changed for the better with the development of modern medical technology, but stomach cancer is an exception.
According to the report of 2014 National Conference on Small Bowel Diseases and Chongqing Endoscopy Forum, the detection rate of early gastrointestinal cancer in China is less than 10%, which is much lower than 70% in Japan and 50% in Korea. The reason is that early gastric cancer has no symptoms, and once there are symptoms, it is already in the middle and late stages, so that the treatment effect of patients is poor, and the quality of life and survival time in the later stage are greatly reduced.
Therefore, early detection of tumor is very important, and regular screening by gastroscopy can improve the detection rate of digestive tract cancer, especially the following 7 high-risk groups of gastric cancer are best to have regular gastroscopy.
Patients with precancerous lesions of stomach
Gastric precancerous lesions refer to benign diseases with a predisposition to gastric cancer, and the common ones are
1.Chronic atrophic gastritis
It is the most common type of precancerous lesion, and its chance of occurrence of gastric cancer can be as high as 10%.
2. Chronic gastric ulcer, the cancer rate is generally less than 3%
If the regularity of ulcer symptoms has changed and increased recently, and there is loss of appetite, vomiting and progressive wasting, attention should be paid to whether cancer occurs.
3.Gastric polyp
It is generally believed that polyps with diameter >2cm, multiple and wide base have high cancer rate.
4.People who have undergone partial gastrectomy
A lot of data show that the risk of cancer in the residual stomach increases by 0.3%-10% after partial gastrectomy.
5.Other precancerous lesions
Such as giant gastric mucosal hypertrophy, warty gastritis, etc. Studies have shown that the rate of H. pylori infection is significantly and positively correlated with the mortality rate of gastric cancer, and the infection of H. pylori may increase the chance of gastric cancer by 2.7-12 times. Therefore, the International Agency for Research on Cancer under the World Health Organization has designated H. pylori as a human class I carcinogen.
People with bad eating habits
Bad eating habits in normal life, such as irregular diet, eating moldy food, eating fast, preferring pickled and smoked food, high salt diet, and eating less fresh vegetables, can lead to stomach discomfort. People often treat these discomfort symptoms as ordinary stomach inflammation and do not pay attention to them, so that the condition gradually deteriorates until it becomes stomach cancer.
Long-term alcoholics and smokers
Smoke contains many carcinogenic or carcinogenic substances such as benzo(a)pyrene, polycyclic aromatic hydrocarbons and dibenzocarbazole, which are one of the causes of esophageal cancer and stomach cancer. Alcohol can stimulate the gastric mucosa and cause changes in the mucosal cells, thus leading to gastric cancer.
Alcohol can also enhance the permeability of cell membranes and thus strengthen the absorption of carcinogenic substances in smoke, so it is even more harmful if alcohol is consumed and smoked at the same time.
In the analysis of risk factors of gastric cancer, it is found that the risk of gastric cancer is significantly higher for those who are mentally stimulated and depressed for a long time. The survey found that nearly 10% of gastric cancer patients had been hit by negative life events prior to the disease. People with family history of gastric cancer or esophageal cancer have obvious tendency to gather in families, and the family incidence rate is 2-3 times higher than that of the general population. It has been found that first-degree relatives (i.e., parents and siblings) of patients with stomach cancer are on average three times more likely to get stomach cancer than the general population.
Studies on certain special occupations show that workers who are often exposed to sulfuric acid dust and mist, lead, asbestos, herbicides, etc., as well as workers in the metal industry have a significantly higher risk of stomach cancer.
Tips for Stomach Care
To prevent the occurrence of gastric cancer, high-risk groups should try to avoid or reduce the various cancer-causing factors they face to lower the incidence rate. Early detection, early treatment and early diagnosis are the only effective ways to screen and treat stomach diseases, especially stomach cancer prevention and treatment.
Please pay more attention to the disease signals of the stomach in general and have regular gastroscopy. Once adverse lesions are detected, you should go to a regular hospital for treatment as soon as possible.
