Esophageal cancer is a cancerous (malignant) tumor of the esophagus, the muscular tube that moves food from the mouth to the stomach.

Esophageal cancer is not very common in the United States. It occurs most often in men over 50 years old.
Two main types of esophageal cancer exist: squamous cell carcinoma and adenocarcinoma. These two types look different from each other under the microscope.
Squamous cell esophageal cancer is linked to smoking and alcohol consumption.
Barrett's esophagus, a complication of gastroesophageal reflux disease (GERD), increases the risk for adenocarcinoma of the esophagus. This is the more common type of esophageal cancer. Other risk factors for adenocarcinoma of the esophagus include:
Tests used to help diagnose esophageal cancer may include:
Stool testing may show small amounts of blood in the stool.
When esophageal cancer is only in the esophagus and has not spread, surgery is the treatment of choice. The goal of surgery is to remove the cancer.
Sometimes chemotherapy, radiation, or a combination of the two may be used instead of surgery, or to make surgery easier to perform.
If the patient is too ill to have major surgery or the cancer has spread to other organs, chemotherapy or radiation may be used to help reduce symptoms. This is called palliative therapy. In such cases, the disease is usually not curable.
Other treatments that may be used to help the patient swallow include:
Patients can often ease the stress of illness by joining a support group of people who share common experiences and problems. See cancer - support group.
Esophageal cancer is usually not curable. When the cancer has not spread outside the esophagus, surgery may improve the chances of survival.
Radiation therapy is used instead of surgery in some cases where the cancer has not spread outside the esophagus.
For patients whose cancer has spread, a cure is generally not possible. Treatment is directed toward relieving symptoms.
Call your health care provider if you have difficulty swallowing with no known cause and it does not get better, or if you have other symptoms of esophageal cancer.
The following may help reduce your risk of squamous cell cancer of the esophagus:
People with symptoms of severe gastroesophageal reflux should seek medical attention.
Screening with EGD and biopsy in people with Barrett's esophagus may lead to early detection and improved survival. People who are diagnosed with Barrett's esophagus should consider getting regular checkups for esophageal cancer.
