Esophagus Cancer

esophagus cancer treatmentEsophagus is the tube that connects mouth to the stomach. This tube helps the food move from the mouth into the throat and down to the stomach to be digested. Esophageal cancer is malignant tumor that occurs in the esophagus. This can happen anywhere along the tube, though it is generally concentrated on the lower part of the esophagus. It usually begins with the cells that are lined in the esophagus. Esophageal cancer can be classified as adenocarcinoma and squamous cell carcinoma.

What causes Esophagus Cancer?

The cells in the esophagus develop mutations in their DNA and divide way out of control. The abnormal, accumulated cells grow into a tumor and infiltrate structures close to it and spread into the body.
Squamous cell carcinoma: Squamous cell carcinoma is associated with drinking excessive amounts of alcohol and excessive smoking. Squamous cells are thin and flat lining the surface of the esophagus. It often occurs in the middle of the esophagus.
Adenocarcinoma: Adenocarcinoma is common and associated with GERD – gastroesophageal reflux disease which can result in Barrett esophagus conditions. It starts with the mucous-secreting glands lodged in the esophagus.
Other: There are other rare types of cancer that may occur in the esophagus such as lymphoma, melanoma, sarcoma, choriocarcinoma and small cell cancer.

Some of the predominant causes of esophageal cancer are:

  • Obesity
  • Drinking very hot liquids
  • Excessive smoking
  • Excessive intake of alcohol
  • Esophageal sphincter – difficulty swallowing
  • Barret’s esophagus
  • Bile reflux
  • Continuous radiation treatments to chest and upper abdomen
  • GERD – Gastroesophageal reflux disease
  • Eating no or less amount of fruits and vegetables

Esophageal Cancer Diagnosis

Biopsy: Cells and tissues from the esophagus is taken and examined under a microscope for cancer.

Barium Swallow: In this method, the patient swallows a liquid, and the passage of this liquid is captured on an x-ray to identify esophageal problems

Endoscopy: A thin tube called an endoscope is passed down the throat. An endoscopic ultrasound apparatus attached to its tip utilizes sound waves to give more information about the tumor.
