The cardia is the link between the esophagus and the stomach in the body, and is an important channel to ensure the smooth entry of the body’s ingested substances into the stomach. And pancreatic cancer is equivalent to a roadblock, a gas pedal that disrupts or even interrupts the normal working order of the passage. At present, the incidence rate of pancreatic cancer is also high in the high incidence area of esophageal cancer in China, and the ratio between the two is as high as 2:1, so pancreatic cancer is gradually among the ranks of high frequency, high risk and high incidence cancers. However, because most people have relatively little knowledge and understanding of pancreatic cancer, they often overlook the pre-cancerous signs and miss the best treatment time.
Early stage symptoms: The early symptoms of cardia cancer are more insidious than other cancers, so it is not easy to detect them in time. Anhui Jimin Cancer Hospital tumor treatment experts pointed out that “cardia cancer is a common lifestyle disease, early symptoms are not obvious, but as long as it is a disease, it has certain characteristics.”
Early symptoms of pancreatic cancer: lesions occur in the lower esophagus, which make the originally narrow pancreatic position more and more narrow, and it is easy to have symptoms very similar to esophageal cancer. It mainly occurs in the body of the stomach, or the head side of the stomach. However, it is difficult to diagnose because there is no obvious pain and local masses in the early stage of the disease.
Early manifestations of pancreatic cancer patients: feeling a strange sensation when food passes through the throat, severe pain, a bit of obstruction, slight heart soreness, and also the above symptoms of distention or slight pain behind the sternum. These symptoms will be felt when swallowing, and they are stronger when swallowing harder foods, especially when drinking hot or cold liquids. Patients with pancreatic cancer sometimes also have blood vomiting or blood in stool. When there is persistent dull pain behind the sternum or in the scapular region of the back, it indicates cancer invasion and causes mediastinitis around the esophagus.
Anatomy of lesion principle: cardia belongs to glandular tissue, when lesions occur in the lower esophagus, cardia will be eroded by cancer cells, resulting in gradual reduction of cardia position. The foreign body sensation when swallowing food mainly comes from the frictional pain caused by the food passing through the cardia, and the pain gradually increases as the disease deteriorates.
