The crude fiber in betel nut is easy to rub the oral mucosa, causing repeated trauma to the mucosa, forming local chronic damage, and then leading to cancer. Areca catechu contains a large number of alkaloids that promote epithelial cell apoptosis, and it is easier to promote cancer when eaten with tobacco. People's physical fitness is different, and their resistance is also different. So far, there is no accurate data in this regard. It is generally believed that eat areca can cause cancer, so we should try to avoid this phenomenon. There are many reasons for cancer. At present, scientific research is inconclusive. It is generally believed that the formation of cancer is related to gene mutation, family history, stimulation of chemical substances and stimulation of carcinogenic factors.
I suggest you avoid eat areca as much as possible. Eat areca may get angry, irritate the throat and cause hoarseness, which is harmful to the respiratory system. At the same time, eat areca is not good for teeth, which will make teeth black, wear and shake, make periodontal inflammation, pain, edema and dental calculus, and may cause oral mucosal fibrosis and oral mucosal leukoplakia.
