Introduction
Esophageal tumors are classified as either benign or malignant. Examples of benign esophageal lesions include polyps, leiomyomas, and adenomas—none of which typically produce distinctive clinical symptoms. Malignant esophageal lesions, such as esophageal carcinoma, may present in the early stage with mild dysphagia, a sensation of food retention, or chest pain. As the disease progresses, patients ultimately develop severe dysphagia due to obstruction.
“Esophageal tumor” is not a scientific term. In clinical practice, we refer to it as “esophageal neoplastic lesions,” which are categorized as either benign or malignant. What are some examples of benign esophageal lesions? These include esophageal polyps, leiomyomas, and adenomas—among others—all of which are benign conditions affecting the esophagus.
When small in size, these benign lesions typically produce no distinctive clinical symptoms. They are usually detected incidentally during gastroscopy examinations. Malignant esophageal lesions also occur, the most common being esophageal carcinoma. In China, the vast majority (>99.5%) of esophageal cancers are squamous cell carcinomas.
In early-stage esophageal cancer, patients may experience mild dysphagia, a sensation of food sticking in the esophagus, or chest pain, among other symptoms. As the disease progresses, patients develop progressive dysphagia: initially, they may feel slight discomfort or difficulty swallowing liquids; eventually, even drinking water may become impossible.
Ultimately, severe esophageal obstruction may develop, rendering patients unable to swallow even a single sip of water. Therefore, individuals experiencing dysphagia or a sensation of esophageal obstruction should promptly consult a physician.
