Diagnosing Esophageal Cancer
To help find the cause of symptoms, the doctor evaluates a person's medical history and performs a physical exam. The doctor usually orders a chest x-ray and other diagnostic tests. These tests may include the following:
A barium swallow (also called an esophagram) is a series of x-rays of the esophagus. The patient drinks a liquid containing barium, which coats the inside of the esophagus. The barium makes any changes in the shape of the esophagus show up on the x-rays.
Esophagoscopy (also called endoscopy) is an examination of the inside of the esophagus using a thin lighted tube called an endoscope. An anesthetic (substance that causes loss of feeling or awareness) is usually used during this procedure. If an abnormal area is found, the doctor can collect cells and tissue through the endoscope for examination under a microscope. This is called a biopsy. A biopsy can show cancer, tissue changes that may lead to cancer, or other conditions.
