Esophageal cancer or GERD? The overlapping symptoms, and the one thing that sets them apart

Heartburn is common, but persistent chest discomfort or difficulty swallowing could signal serious issues. Gastroesophageal reflux disease, or GERD, involves stomach acid backing up into the esophagus. Esophageal cancer is rarer but more dangerous. While symptoms overlap, GERD symptoms often fluctuate and respond to treatment. Cancer symptoms tend to worsen and persist. Early detection is key for both conditions.
