Esophageal Cancer

Image
The esophagus is a 10-inch long, hollow, muscular tube that connects the throat to the stomach. It is part of a person’s gastrointestinal (GI) tract. When a person swallows, the walls of the esophagus squeeze together to push food down into the stomach.Cancer begins when normal cells change and grow uncontrollably, forming a mass called a tumor. A tumor can be benign (noncancerous) or malignant (cancerous, meaning it can spread to other parts of the body). Esophageal cancer, also called esophagus cancer, begins in the cells that line the esophagus.Specifically, cancer of the esophagus begins in the inner layer of the esophageal wall and grows outward. If it spreads through the esophageal wall, it can grow into lymph nodes (the tiny, bean-shaped organs that help fight infection), blood vessels in the chest, and other nearby organs. Esophageal cancer can also spread to the lungs, liver, stomach, and other parts of the body.
