Drinking polluted water is a risk factor for liver cancer

As early as the 1970s, medical workers in my country discovered that in areas with a high incidence of liver cancer, the incidence of liver cancer is closely related to the source of drinking water.

Data show that in my country's high-incidence areas of liver cancer, residents who drink ditch and pond water have the highest incidence and mortality rates of liver cancer, followed by those who drink river water, and those who drink deep well water have the lowest. This fully proves that drinking water pollution is related to the incidence and mortality rates of liver cancer. For example, in Qidong County, Jiangsu Province, Nanhui County, Shanghai, Fusui County, Guangdong Province and other places, the mortality rate of liver cancer patients who drank surface water was significantly higher than that of those who drank well water.

Through the analysis of ditch and pond water, it was found that there are more than 100 carcinogenic or cancer-promoting substances in the water, such as hexachlorobenzene, benzopyrene, polychlorinated biphenyls, etc., which have carcinogenic effects. It was also found that cyanobacteria often breed in ditch and pond water, and green algae can produce microcystin, which is highly toxic to the liver and can cause damage and necrosis of liver cells. It is a strong cancer promoter.

Water pollution is mostly caused by the indiscriminate construction of factories for industrial development, but no pollution reduction measures are taken, which eventually harms nearby residents. Residents can raise funds to dig deep wells. Deep well water is generally less polluted. If there are no conditions to dig a deep well, you can drink water that has been purified by the water plant. At the same time, you cannot drink raw water and must boil it before drinking.
