Recently, the U.S. Department of Health and Human Services released the 15th edition of the carcinogen report, which added 8 new carcinogens. Including chronic infection of Helicobacter pylori is listed as a clear carcinogen, antimony trioxide is listed as a reasonably suspected carcinogen, and 6 kinds of halogenated acetic acid by-products after disinfection of tap water are considered to have teratogenic and carcinogenic side effects.

Especially Helicobacter pylori is extremely common in daily life. According to the “Investigation and Research on the Correlation between HP Infection Rate and Different Environmental Factors”, Helicobacter pylori (Hp) is the most common chronic bacterial infection in humans, accounting for more than 50% of global natural bacterial infections. Among them, the infection rate in developing countries exceeds that in developed countries. According to the 2001-2014 National Helicobacter Pylori Survey, the Helicobacter pylori infection rate in my country is between 40%-90%, with an average of 59%.

The development of gastric cancer has a certain process, among which Helicobacter pylori infection is a key factor leading to gastric cancer. In the 15th report on carcinogens issued by the U.S. Department of Health and Human Services (HHS), chronic infections caused by Helicobacter pylori were listed as clear human carcinogens.

In addition, in recent years, a series of studies have shown that Helicobacter pylori infection can significantly increase the risk of gastric cancer. At the same time, people have found a variety of mechanisms by which Helicobacter pylori induces gastric cancer.

In fact, for “carcinogens”, as early as 2017, the International Agency for Research on Cancer under the World Health Organization compiled and published a list of 4 types of carcinogens based on their correlation with cancer, which is considered to be the most comprehensive so far “List of carcinogens.” After combing through this list, we can find that it specifically includes: Category 1 is a confirmed carcinogen for humans; Category 2 has limited evidence of carcinogenicity to humans; Category 3 is suspicious of carcinogenicity to humans; Category 4 is a substance that may not be carcinogenic to humans. .

Among them, there are 120 types of carcinogens in Category 1 (the highest level of carcinogens), including alcoholic beverages, salted fish, air pollution, solar radiation, and smoking that are closely related to people’s daily lives. But it needs to be emphasized that exposure to these substances does not necessarily cause cancer, but represents a higher risk. But there is also evidence that long-term exposure to Category 1 carcinogens can increase the risk of cancer.
