Choking sensation when swallowing food is not esophageal cancer, but there are many clinical diseases that cause choking sensation. Choking sensation is a feeling of difficulty in swallowing food after eating, with obvious stagnation, which may be accompanied by foreign body sensation and pain during the process, but the food can pass through the esophagus after swallowing hard. The choking sensation, which aggravates clinically, is a typical clinical manifestation of esophageal cancer, while some other diseases can also cause choking sensation, mainly as follows: 1, esophagitis: especially reflux esophagitis causes foreign body sensation and difficulty in swallowing due to mucosal edema; 2, pancreatic flaccidity: the loss of normal function of pancreatic sphincter muscle causes different pressure between esophageal and gastric cavity, which leads to peristaltic uncoordination and difficulty in passing food, resulting in choking sensation 3, esophageal smooth muscle tumor: If smooth muscle tumor grows large and protrudes into the lumen of the esophagus, it can lead to difficulty in passing food and foreign body sensation with choking sensation; 4, mediastinal disease: The mass grows large and can compress the esophagus causing luminal narrowing, which leads to difficulty in swallowing.
