Most esophageal tumors are malignant, but of course there are also benign possibilities. For example, esophageal adenoma or smooth muscle tumor, but there are also some junctional tumors. For example, spindle cell tumors located in the esophagus are in between benign and malignant, but they can be treated very well. The diagnosis of esophageal tumor may not be fully confirmed until pathological examination is done. Imaging examinations, including upper gastrointestinal tract imaging, may reveal occupying lesions in the esophagus, and the patient may show symptoms of choking. Therefore, based on the symptoms and imaging examination alone, we can only judge that there is a tumor in the esophagus, but we have to rely on pathological examination to determine the nature. If the tumor is located in the outer wall of esophagus, there may be no way to take pathology and surgery is needed to determine the nature.
