Esophageal cancer, also known as esophageal cancer, is one of the common malignant tumors in human beings. Worldwide, about 300,000 people die of esophageal cancer every year. China is a high incidence area of esophageal cancer, and about 6.5438+0.5 million people die of esophageal cancer every year, accounting for nearly a quarter of all malignant tumor deaths. The mortality rate of esophageal cancer varies greatly in different parts of China. According to the national retrospective survey of malignant tumor deaths, the adjusted mortality rate of esophageal cancer in Yunnan Province is the lowest (105/65438+ 10,000), which is 14 times different from the national level and 3 1 times different from the highest mortality rate in Henan Province. There are obvious regional differences in the incidence of esophageal cancer. The high incidence areas of esophageal cancer in China are: Taihang Mountain area in North China, including Linxian County in Henan Province, Cixian County in Hebei Province and Yangcheng City in Chongshan Province. The onset age of the elderly group is higher, and the onset age is mostly over 40 years old, with more males than females. In recent years, the number of patients under 40 years old has increased, and gradually decreased after 70 years old. The average age of esophageal cancer death in China is 63.49 years old, and the proportion of each age group is different, with the highest proportion of 55-74 years old. This shows that esophageal cancer is a common disease in middle-aged and elderly people.
Western medicine believes that the esophagus is located at the back of the throat and chest cavity, which is a muscle tube connecting the throat and stomach and a channel for food to enter the stomach for digestion. Walking vertically behind the chest, in front of the spine, behind the heart and trachea, slightly to the left when approaching the diaphragm, passing through the diaphragm and connecting to the upper entrance of the stomach and cardia. Its length is about 10 inch.
25~35
About 10 ~ 13 between centimeters.
Inch, about 35 ~ 40 cm from the front teeth to the stomach entrance. The normal width of adult esophagus is about 1.9 cm, while the anterior-posterior diameter is narrow, less than half a centimeter.
Traditional Chinese medicine believes that esophageal cancer belongs to the category of choking diaphragm in ancient times. Neijing says: "If the obstruction is closed and the upper and lower parts are blocked, the anxiety disease will occur", "The stagnation of three yang is called diaphragm", "If you can't eat, the diaphragm will choke, if you eat, you will vomit" and "If you are in the diaphragm, you will eat and drink, and you will foam". These symptoms are similar to those of esophageal cancer. Article source: Esophageal cancer in China (
