Esophageal Cancer

Cancers beginning in the esophagus typically form within the inner layer of cells and gradually grow outward. Squamous cell carcinoma usually begins this way and is mostly seen in the upper or middle parts of the esophagus. If allowed to advance, the cancer can grow into the lymph nodes and spread to other parts of the body, with lungs, liver, and stomach being the most common sites of metastases. Adenocarcinoma is another type of esophageal cancer that usually forms in the glandular tissue near the base of the esophagus.
