In Hunan, Hainan, Taiwan and other places, can be seen everywhere in the street chewing areca. From youth to old man, this kind of black brown, sticky snacks are loved by people of all ages. However, the international cancer research center in 2003 as early as in as a class of carcinogens, but this did not arouse public attention.
 
Hainan is the largest producer of areca in China, while Hunan is a big province of areca. Areca tastes bitter and astringent, with sweet and spicy mild irritation, containing ingredients such as arecoline fever, make people excited, can be refreshing, relieve fatigue, which makes many people unable to stop. A survey conducted by Central South University in 5 cities in Hunan showed that about 16.2% of people like to chew areca. According to experts projections, Hunan, about 11 million 340 thousand people chew areca. Hunan, Xiangtan is the most prominent, according to WHO data estimate that 80% of Xiangtan residents have the habit of chewing areca, but also the mouth lesions are also wrapped around them.
Xiangya Hospital of Central South University has conducted a survey found that 66% of those who chew areca oral mucosal lesions, and do not chew the areca this data is only about $1.5% in Xiangtan. Oral submucous fibrosis is a chronic, occult, premalignant oral mucosal disease, manifested as blisters, dry mouth, burning mouth occurs, partial or full mouth mucosa pale, and have different degrees of trismus, canceration rate is 7.6%~10.45%. According to a rough estimate, 60% of oral cancer patients in Hunan and areca. An epidemiological survey in 90s showed that people who did not chew areca had an oral cancer rate of about 0.3%, while those who chewed areca rose to 7.6%, which is believed to be a significant increase today. A new report from the Department of health in Taiwan shows that the number of people with oral cancer in Taiwan has increased by nearly 3 times in the past 10 years, with a total of more than 90% of patients suffering from chronic oral areca.
Areca's addiction to the field to a lot of people deeply fell in love with it. In my admissions of patients, there is a 25 year old Henan guy, just came to Changsha soon fell in love with areca. Start chewing one or two packs a day, and then develop to a daily four or five packs. About 5 years later, he felt very hot mouth pain, then even talk difficult, was diagnosed with oral submucous fibrosis, and transformed into oral cancer.
Areca will increase the risk of oral cancer, there are 4 main reasons. First, areca in arecoline, after chewing the formation of carcinogenic N-nitroso compounds. Second, areca is relatively hard, especially with areca leaves and lime wrap, the more severe wear on the mouth, so that the long-term damage to the state of the mucosa. Third, lime with strong alkaline and irritating, will cause the imbalance in the pH of the mouth, causing cancer. Fourth, people tend to love chewing areca love smoking, two “ &rdquo, jointly promote the formation of like drawn to like; oral cancer. Once suffering from oral cancer, patients not only to bear the pain of surgery, but also face high medical costs. Therefore, it is recommended that residents in Hunan, Hainan and other places like quitting smoking, try to quit areca.
So, how to prevent oral cancer chewing areca history of long people? We should pay more attention to oral hygiene, proper brushing, regular cleaning, removal of dental calculus. The survey showed that people who can not adhere to the brush every day, the risk of tongue cancer increased by 2.1 times, the risk of other parts of the mouth tumors increased by a factor of 2.4. Secondly, to balance the diet, eat more vegetables, fruits, reduce fat intake, avoid excessive hot food stimulation. Finally, to avoid sharp teeth, residual roots, residual crown and other chronic chronic irritation, injury. If there is a long period of time (more than two weeks) of oral ulcers, oral leukoplakia thickening and accompanied by chapped, the need for timely medical treatment, pathological examination to confirm.
