C15: Malignant neoplasm of oesophagus

Malignant neoplasm of the oesophagus, commonly known as esophageal cancer, is a serious condition where cancer cells form in the tissues of the oesophagus, the tube that moves food and liquid from your mouth to your stomach. This group of conditions typically starts in the inner layer of the oesophagus and can spread outward to other layers as it progresses. Common symptoms could include difficulty swallowing, unexplained weight loss, chest pain, and a persistent cough, often with blood. While the exact cause of esophageal cancer is unknown, risk factors include smoking, heavy alcohol use, age, and certain medical conditions like gastroesophageal reflux disease. It is not a contagious disease and cannot be passed from person to person. Each type within this group affects different parts of the oesophagus and may progress at varying rates.
