Esophageal cancer is cancer that occurs in the esophagus — a long, hollow tube that runs from your throat to your stomach. Your esophagus helps move the food you swallow from the back of your throat to your stomach to be digested.
Esophageal cancer usually begins in the cells that line the inside of the esophagus. Esophageal cancer can occur anywhere along the esophagus. More men than women get esophageal cancer.
Esophageal cancer is the sixth most common cause of cancer deaths worldwide. Incidence rates vary within different geographic locations. In some regions, higher rates of esophageal cancer may be attributed to tobacco and alcohol use or particular nutritional habits and obesity.
