Esophageal space occupation refers to a condition in which abnormal growths are generated in the esophagus due to diseases such as esophageal polyps and esophageal cancer, resulting in narrowing or blockage of the esophagus. There are benign and malignant cases. 1. Benign esophageal space occupation: esophageal stenosis or obstruction caused by polyps, inflammatory hyperplasia and mesenchymal tumors in the esophagus are generally considered as benign esophageal space occupation. 2. Malignant esophageal space: esophageal stenosis or obstruction caused by esophageal cancer, esophageal lymphoma and malignant mesenchymal tumor of the esophagus are usually malignant esophageal space. If you have difficulty in swallowing or swallowing food, there may be esophageal occupation, so please consult a doctor in time and complete the relevant examinations under the doctor’s guidance to clarify the nature of esophageal occupation.
