The differences between esophagitis and esophageal cancer are significant. Esophagitis is an inflammation and is benign, but esophageal cancer is malignant, marking a stark contrast between the two. However, both esophagitis and esophageal cancer can have similar clinical symptoms, such as acid reflux, hiccups, heartburn, pain behind the breastbone, discomfort, and a burning sensation behind the breastbone, so symptoms can be similar. However, a more typical symptom of esophageal cancer is a sensation of swallowing obstruction, since there is actually something in the esophagus. Inflammation, after all, is just that, and it does not involve a mass forming inside the esophagus that could block it, hindering the ability to drink water, eat food, or swallow.
