In fact, the saying that betel nut chewing is regarded as a "suspect" of oral cancer has a long history. China, Taiwan Province, Hunan, Hainan, Guangdong and other places have high betel nut production and high incidence of oral cancer.

"However, due to the complicated inducing factors of cancer, whether betel nut is directly related to oral cancer is still inconclusive in the medical field." Guan, director of the periodontal mucosa department of Beijing Stomatological Hospital, told the reporter.

At present, the mainstream view about oral cancer caused by chewing betel nut is that the most common way to eat betel nut is to use flowers and lime eat areca. Areca catechu contains a lot of arecoline (with cytotoxicity and genotoxicity), and flowers contain more recognized carcinogen safrole, which will inhibit the synthesis of cellular DNA in human body and lead to oral mucosal lesions. Betel nut with flowers is equivalent to adding cancer promoters to carcinogens.

Moreover, in the process of chewing betel nut, oral mucosa will react with alkaloids and various nitrosamines contained in betel nut. Nitrosamines are considered to be the basic factors causing oral mucosal lesions. Long-term exposure of oral mucosa to this environment will lead to pathological changes and fibrosis of oral mucosa, and then lead to oral cancer.

Experts remind that oral hygiene should be maintained in daily life, smoking and drinking should be stopped as much as possible, dentures should not be worn out, teeth roots should be adjusted and sharpened, and chronic oral inflammation should be treated in time to prevent problems before they occur.
