China is a high incidence country of esophageal cancer. What habits can lead to esophageal cancer?

Esophageal cancer is a common cancer of digestive tract. Many people die of esophageal cancer all over the world every year. China has gradually become one of the countries with high incidence of esophageal cancer. According to statistics, esophageal cancer ranks fourth among the causes of death of malignant tumors in China, that is to say, China has become one of the countries with high incidence of death of esophageal cancer in the world. So what are the causes of esophageal cancer? This article introduces the bad habits that can easily lead to esophageal cancer. Let's learn about them together, stay away from these bad habits, and let esophageal cancer stay away from you.

The incidence and death of esophageal cancer in China account for about half of the world. The incidence of esophageal cancer in the world is 572000 and 508000 people die every year. In China, there are 307000 cases of esophageal cancer and 283000 deaths every year. The chronic burn caused by overheating diet is one of the important factors inducing esophageal cancer.

In the areas with high incidence of esophageal cancer (Taihang Mountains at the junction of Henan, Hebei and Shanxi, as well as northern Sichuan, Northern Jiangsu and Northern Fujian), people with family history, long-term smoking and drinking over the age of 40.

The typical symptom of esophageal cancer is progressive dysphagia, first difficult to swallow dry food, then semi liquid food, and finally water and saliva can not be swallowed. Eat and drink while hot & hellip& hellip; Many people have this habit in their life. Unexpectedly, esophageal cancer also focuses on people who like to take advantage of the heat!

In the carcinogen assessment report officially published in the Lancet Oncology on June 15, 2016, the international agency for research on cancer (IARC) listed very hot (above 65 ℃) drinks as very likely (IIA) carcinogens.

The study found that people in China, Turkey and South American countries and regions are usually used to drinking water, coffee or tea at 65 ℃ or above 70 ℃, which increases the risk of esophageal cancer.

Not that eating too hot will get cancer, but eating too hot will increase the risk of cancer.

Our oral cavity and esophagus are covered with soft mucosa. Under normal circumstances, the temperature of oral cavity and esophagus is mostly 36.5 ℃ - 37.2 ℃, and the tolerable high temperature is only 50 ℃ - 60 ℃. When the mouth feels very hot, the temperature is mostly around 70 ℃.

People who often eat hot food are used to high temperature in their mouth. When the food temperature is very high, I don't feel hot, but the actual damage already exists. When exposed to hot food and drink above 65 ℃, the esophageal mucosa will be slightly burned. When injured, tissue cells begin to regenerate. However, if the oral and esophageal mucosa is often scalded, it will cause chronic inflammatory reaction of esophageal mucosa, which will increase the risk of esophageal carcinogenesis.

These bad habits can also contribute to esophageal cancer:

1. Pickled and moldy food

Aflatoxin or nitrite is easily produced in pickles and moldy peanuts. They cause chemical damage to the esophageal mucosa. This kind of damage will directly form punctate lesions, and then the area will become larger and larger until canceration.

2. Baked and fried food

Barbecue and fried foods also contain many carcinogens such as nitrite.

3. No spicy

Studies have shown that eating too much pepper is associated with an increased risk of cancer. Too spicy food is easy to damage esophageal epithelium, cause epithelial cell degeneration, cause mucosal inflammation, affect cell nucleic acid metabolism, increase the sensitivity of carcinogens, and may promote esophageal carcinogenesis.

4. Smoking and drinking

Among people who smoke and drink alcohol, the incidence of esophageal cancer will also increase. Many carcinogens in tobacco can enter the esophagus with saliva or food, and over time attack the esophageal mucosa, causing esophageal cancer. The strong liquor causes physical stimulation and damage to the esophageal mucosa, which will directly leave scars on the esophageal mucosa.

5. Eat too fast

Eating too fast will make the food unable to chew fully. Coarse food is easy to damage the esophageal mucosal epithelium and cause acute inflammation.
