Esophageal cancer is a cancerous (malignant) tumor of the esophagus, the muscular tube that moves food from the mouth to the stomach. Esophageal cancer is not very common in the United States. It occurs most often in men over 50 years old. Two main types of esophageal cancer exist: squamous cell carcinoma and adenocarcinoma. These two types look different from each other under the microscope.(1)
“Once a rare cancer representing only 5 percent of all esophageal cancers in the United States, esophageal adenocarcinoma is the cancer with the fastest-rising incidence — six-fold increase in the past three decades — and currently comprises more than 80 % of all new esophageal cancer cases in this country,” said Xifeng Wu, M.D., chair of the Department of Epidemiology, Division of Cancer Prevention and Population Sciences at The University of Texas MD Anderson Cancer Center, in Houston. “To reduce the mortality of esophageal adenocarcinoma, the best hope in the near term is to detect it at its early stage, or even better, to prevent the progression of esophageal adenocarcinoma from its premalignant lesion, which is called Barrett’s esophagus.”(2)
