Esophageal cancer is second only to gastric cancer in terms of prevention rate, which brings a lot of pain to people’s life, because they do not know that some common habits in our daily life can increase the chance of esophageal cancer. Which are those habits, let’s take a look. The esophagus is the passage of food from the mouth to the stomach. The wall of the esophagus is an elastic tissue, which consists of mucosal epithelial layer, submucosal layer and muscle layer. The innermost layer of the esophageal cavity is the mucosal epithelium, thin and soft, it is in direct contact with the food, and the most frequent and close, so it is easy to be stimulated by a variety of food. Eating too fast will make the food can not be fully chewed, those particles rough, high temperature meals, it is easy to damage the fragile esophageal mucosa epithelium, triggering acute inflammation. If a person has the habit of eating too fast, then these acute inflammation will probably form chronic inflammation, which may lead to esophageal cancer in the long run. It is recommended to develop the good habit of chewing and swallowing slowly, but chewing and swallowing slowly does not mean that the slower the better, the best time for each meal is about 20 to 30 minutes, which does not include the time for chatting and socializing during meals. 2.Sleeping on the right side for a long time Some studies found that esophageal cancer and sleep are also related. In terms of the degree of acidity of esophagus, those who sleep on the right side have the greatest degree and those who sleep on the left side have the least degree. This is because sleeping on the side affects the position of the esophagus and the stomach. When a person sleeps on the right side, the stomach is higher than the esophagus, and stomach acid tends to flow back into the esophagus. This is less likely to happen when sleeping on the left side. Therefore, if one sleeps on the right side every time, it will easily lead to acid reflux to the esophagus, which will lead to sore throat, shortness of breath, tight pressure on the chest and other symptoms in serious cases. 3.Drinking “hot tea” Many people have the habit of drinking tea, especially in the southern region. Incorrect tea drinking habits can lead to esophageal cancer, as the mucous membrane is stimulated by tea, leading to damage and bleeding, and may cause cellular problems, resulting in digestive problems. The reason why people at risk of esophageal cancer are advised not to drink tea is that clinical observation shows that many people have the habit of drinking “first sip of tea” and “hot tea”, which will cause mucosal congestion and damage the mucosa, thus destroying the protective function of the mucosa. . 4, crazy weight loss Some women in the pursuit of the ultimate body will take extreme weight loss, such as long-term consumption of single-generation meal food, such as long-term intake of very little food to lose weight. This may cause the body to lack a variety of essential vitamins and trace elements, especially vitamin A, vitamin B, molybdenum and so on. The lack of these vitamins and trace elements will affect the normal division and metabolism of the epithelial cells of the esophagus, and if this state is not changed for a long time, there is a risk of developing esophageal cancer. 5.Eating betel nut The chemicals in betel nut will produce some oxygen free radicals that can cause cancer. Some of the ingredients are also nitroxylated when chewed in the mouth, and some of them have been proven to have strong carcinogenic effects. These components can alter the local tissue structure of the esophagus, causing epithelial atrophy, submucosal fiber accumulation, reduced blood flow, and vitrification of submucosal tissue, while reducing the resistance and immunity of the patient’s local tissues, which facilitates the activity of carcinogenic components. In addition, betel nut itself is a kind of irritating food, which adds another layer of influence on the esophagus, and combined with various reasons, it is easy to trigger esophageal cancer.
