Esophageal cancer is a disease that occurs in the esophagus – a long tube that runs from your throat to your stomach which carries food and liquids to the stomach for digestion.
Liver cancer usually begins in the tissues or nodules of the liver, but can also occur within cells of the liver bile ducts.
Pancreatic cancer occurs when abnormal cells within the pancreas form a tumor. The disease forms in one of two different types of glands: exocrine (glands that make enzymes to aid digestion) and endocrine (hormone-making glands).
Stomach cancer (gastric cancer) forms in the tissues of the stomach. Cancerous cells can develop in any of the five layers of the stomach, from the innermost layer, the mucosa, to the outermost layer, the serosa.
