The incidence of gastric cancer is related to the geographical environment

The occurrence of cancer is the result of the combined effects of various physical, chemical and microbial factors, and its incidence is closely related to the geographical environment.

In my country, high-incidence areas of gastric cancer are often concentrated in volcanic rock areas, most of which are high peat, while low-incidence areas are concentrated in limestone areas. For example, the mortality rate of gastric cancer in Qinghai, where the incidence of gastric cancer is the highest, differs by 7.9 times from that in Guangxi, where the incidence is the lowest. This supports the idea that gastric cancer is related to environmental factors.

In recent years, people have gradually begun to pay attention to the relationship between trace elements and tumor occurrence. The so-called trace elements refer to elements whose content in the human body is less than one ten-thousandth. These trace elements are taken into the human body through food and drinking water. Generally speaking, when the zinc and nickel content in the diet increases, the incidence of gastric cancer also increases. The trace element selenium is also related to the occurrence of gastric cancer. When the selenium content decreases, the incidence of gastric cancer increases. This is because when selenium is deficient, in addition to inhibiting and weakening the tumor, it can also reduce the body's immunity and easily lead to gastric cancer.

Tips: Gastric cancer high-incidence areas related to geological water quality include the Hexi Corridor of the Qilian Mountain inland river system, the upper reaches of the Yellow River, and the Yangtze River.

The lower reaches, the mouth of the Minjiang River, the lower reaches of the Mulan River and the southern section of the Taihang Mountains. If you live in a high-incidence area of ​​gastric cancer, please test the trace elements in your body in time and take appropriate measures to eliminate or supplement them. The earlier gastric cancer is discovered, the more beneficial it is for treatment and recovery.
