What causes gastric cancer? Pay attention to these four aspects

Gastric cancer is a very common malignant tumor. Once you have gastric cancer, it will cause great harm to our lives. Therefore, the harm of gastric cancer cannot be ignored. There are four main causes of gastric cancer. The first is dietary reasons. A large amount of pickled food will increase the probability of causing gastric cancer. The second is long-term sulking. People who sulk for a long time have a higher incidence of gastric cancer than normal people. The third is heredity. If a relative has gastric cancer, then the probability of having gastric cancer is dozens of times that of a normal person. The fourth is Helicobacter pylori infection, which will also promote the spread of cancer cells.

The incidence of gastric cancer in my country is very high. We must do a good job of relevant preventive care to avoid the occurrence of gastric cancer. So, how is gastric cancer caused? I believe many people want to know more. Let's take a look at the following introduction.
1. Dietary factors <br/>Dietary factors are the main cause of gastric cancer, because many people now like to eat pickled foods, so the risk of gastric cancer is also very high. Pickled foods contain large amounts of nitrosamine compounds. A large amount of nitrosamines accumulate in the stomach for a long time, which can cause gastric cancer. People who like to eat high-protein foods also have a very high incidence and mortality rate of gastric cancer.
2. Sulking for a long time <br/>If a person sulks for a long time, the probability of developing stomach cancer will be much higher than that of normal people. Those who are slow, stagnant, cold or impatient have a slightly lower risk, while those who are cheerful, pessimistic and lively have the lowest risk. Therefore, it is important to maintain a good attitude every day, and you must learn to adjust when anything happens.
3. Heredity and genes <br/>According to research, if a relative has gastric cancer, the probability of the relative suffering from gastric cancer is four times higher than that of a normal person. The carcinogenesis of gastric cancer is a multi-factor, multi-step, and multi-stage development process, involving changes in oncogenes, tumor suppressor genes, apoptosis-related genes, and metastasis-related genes, and the forms of gene changes are also diverse.
4. Helicobacter pylori infection <br/>More than half of the patients with gastric cancer are infected with Helicobacter pylori, because Helicobacter pylori can promote the conversion of nitrates into nitrites and nitrosamines, which are carcinogenic; Hp infection causes chronic inflammation of the gastric mucosa and environmental pathogenic factors accelerate the excessive proliferation of mucosal epithelial cells, leading to deformation and carcinogenesis; the toxic products of Helicobacter pylori, CagA and VacA, may have a carcinogenic effect, and the detection rate of anti-CagA antibodies in gastric cancer patients is significantly higher than that in the general population.
