In 2003, the International Center for Research on Cancer put Areca catechu on the "blacklist", which is the first-class carcinogen with tobacco, alcohol and arsenic. Cancer has two causes:
First, the chemical substances in betel nut after chewing form nitroso, which is a carcinogenic compound.
Secondly, betel nut is hard, and it is easy to cause mechanical trauma to oral mucosa when chewing.
CCTV reported that betel nut is closely related to the incidence of oral cancer. John Zhang, a physician at the Stomatology Center of the Second Xiangya Hospital of Hunan Central South University, explained that "about 60% of oral cancer patients are related to eat areca".
Extended data
Chewing betel nut regularly will not only seriously damage teeth, but also lead to red and black teeth, and even fall off early, and there is a high risk of cancer. As early as 2003, the International Center for Research on Cancer under the World Health Organization had identified betel nut as a first-class carcinogen.
The medical community believes that chewing betel nut often causes oral ulcers, gingival degeneration, submucosal fibrosis, and then leads to oral cancer. Medical research has found that chewing betel nut will increase the risk of oral cancer by 8.4-9.9 times. Arecoline and arecoline in areca catechu are potentially carcinogenic, and both flowers and vines of areca catechu contain carcinogens.
