Esophageal cancer (or oesophageal cancer) is malignancy of the esophagus. There are various subtypes, primarily adenocarcinoma (approx. 50-80% of all Esophageal cancer) and squamous cell cancer. Squamous cell cancer arises from the cells that line the upper part of the esophagus. Adenocarcinoma arises from glandular cells that are present at the junction of the esophagus and stomach. Esophageal tumors usually lead to dysphagia (difficulty swallowing), pain and other symptoms, and are diagnosed with biopsy. There are many new options for treatment that can minimize trauma, improve outcomes and lessen recovery times. Innovative technologies are allowing surgeons to remove cancer with minimum damage to surrounding tissue, and new minimally invasive surgery techniques allow for fewer side effects and better quality of life.
