Esophageal Cancer

Squamous Cell Carcinoma is a condition in which abnormal squamous cells (the cells that make up part of the mucous membrane that lines the esophagus) divide and spread uncontrollably. In the past, squamous cell carcinomas were responsible for nearly 90% of all esophageal cancers. However, they now make up less than 50% of esophageal cancers. Adenocarcinomas occur in glandular tissue and not in squamous tissue. Before an adenocarcinoma can develop, glandular cells must replace an area of squamous cells, as in the case of Barrett’s esophagus. This transformation is most common in the lower esophagus, which is the site of most adenocarcinomas.
