In 2003, the international center for research on cancer published the conclusion that "areca nut itself is the first type of carcinogen", which is the authoritative conclusion after collecting hundreds of areca nut research reports from seven countries and regions, including Taiwan, and Pakistan. This conclusion also tells people, often eat areca nut may cause cancer. Besides, a 2010 study by the Taiwan institute of health showed that the percentage of oral cancer cases in the public could be attributed to betel nut chewing (38%) and smoking (31%). The researchers also called for people to quit betel nut and quit smoking to prevent oral cancer.
