4) Heartburn
Chest pain may also appear as heartburn, which is felt either as pressure or as a burning sensation to the middle part of the chest. This type of pain is independent of chewing or passing food through the esophagus and may become a continuous symptom caused by stomach acid alterations instead of esophageal cancer itself. Thus, heartburn is considered to be an ailment closely related to esophageal cancer, sometimes deeply associated with its appearance in the first place.
