As the saying goes, "nine out of ten people have stomach problems", stomach discomfort, acidity and bloating have become the common diseases of modern people. But when it comes to stomach cancer, many people still think it is far away from them. Zhejiang Jinhua, a college student Xiaowen, almost every day after self-study to go to "rub a meal", and sometimes barbecue as a staple food.

　　Dietary habits, environmental pollution to the high incidence of stomach cancer

　　The annual report released by National Tumor Registry Center shows that the incidence of stomach cancer is mainly concentrated in the western part of China as well as the southeastern coastal provinces, such as Shanghai, Jiangsu, Qinghai, Gansu, etc. The incidence rate of stomach cancer in men is much higher than that of men in China. The incidence rate of stomach cancer in men is much higher than that in women, especially in middle-aged men, who suffer from gastric polyps, gastric ulcers, chronic atrophic gastritis and other diseases, which are likely to develop into stomach cancer if left untreated for a long time.

　　According to the data, in the past 5 years, there are 400,000 new cases of stomach cancer in China every year, and the incidence rate accounts for about 42% in the world; it is expected that by 2015, the incidence rate of stomach cancer in China will climb by 1.6% per year.

　　Experts believe that the high incidence of stomach cancer among Chinese people is related to their unique dietary habits, such as Chinese people love to eat barbecued lamb kebabs, hot pots, spicy, pickled food, etc., and food with too heavy taste will stimulate the digestive tract and cause organ lesions; more alcohol consumption among Chinese people is also a reason, and drinking too much white wine not only harms the liver, but also has a negative impact on the whole digestive tract.

　　In addition, the incidence of stomach cancer in recent years, and environmental pollution also has a lot to do. Polluted water and food can stimulate the digestive tract and cause damage to the stomach. In addition, pesticide residues and drug abuse can likewise lead to an increase in digestive system cancers.

　　What bad habits are most likely to cause stomach cancer

　　1、Those who often drink very hot strong tea

　　Drinking high-temperature (above 80 degrees Celsius) strong tea often not only burns the esophagus easily, forming chronic ulcers in the esophagus, but also the tannin in the tea is more likely to stimulate the injured esophageal epithelial cells due to its deposition in the damaged area, prompting the chronic ulcers to remain unhealed for a long period of time, leading to cancer.

　　2、Frequently stay up late

　　Cancer cells are formed by mutation in the process of normal cell fission. Night time is the most vigorous period of cell fission. If there is insufficient sleep at night and the human body's ability to resist diseases is lowered, it is difficult to control the mutation of cells and the formation of cancer cells. People who stay up late for refreshing often smoke and drink coffee, but also easy to make more carcinogens invade the human body.

　　3、People who hold their urine and feces

　　The risk of bladder cancer is directly proportional to the time of urine retention. Urine contains a carcinogen that can invade bladder muscle fibers and make them cancerous. There are even more harmful substances in stool, hydrogen sulfide, fecal odorant and other carcinogens, which can also lead to cancer if they regularly irritate the intestinal mucosa.

　　4、Preferring to eat meat

　　Experts found that people who eat pork, beef, sheep and other animal meat as their main food every day, the proportion of those who suffer from intestinal cancer is 2.5 times higher than those who only eat a small amount of meat several times a month; the risk of pancreatic cancer also increases with the increase in the amount of meat eaten.
