Back pain in esophageal cancer is pain in the middle of the back. Since the esophagus is located roughly in front of the spine, back pain in esophageal cancer tends to be pain in the middle of the back, or between the shoulder blades on both sides. This pain is often vague and there is no specific pain site. And some esophageal cancer patients’ pain is felt behind the sternum instead of feeling back pain. When the esophagus is located more downward, sometimes the ulcer on the surface of the tumor will produce pain in the upper abdomen and pain below the glabella due to the irritation of stomach acid. Therefore, if there is a long and continuous pain in these areas, it is necessary to be alert to the possibility of esophageal cancer and go to hospital for examination as soon as possible.
