Cancer Esophageal Underlying Cause
The cause of esophageal cancer is unknown, but genetics may play a role in determining risk.
Genes control the functions inside a cell. Special genes control how cells divide and grow. Cancer occurs when the damaged genes stimulate the cell to multiply out of control. The exact cause for this damage is unknown.
Cancer cells can develop from any tissues inside the esophagus: the lining, glands or muscles. The cells can spread through the lymphatic system or the bloodstream. Esophageal cancer spreads most commonly to the lungs and liver.
