It's thought that chronic irritation of your esophagus may contribute to the DNA changes that cause esophageal cancer. Factors that cause irritation in the cells of your esophagus and increase your risk of esophageal cancer include:

  • Drinking alcohol
  • Having bile reflux
  • Having difficulty swallowing because of an esophageal sphincter that won't relax (achalasia)
  • Drinking very hot liquids
  • Eating few fruits and vegetables
  • Having gastroesophageal reflux disease (GERD)
  • Being obese
  • Having precancerous changes in the cells of the esophagus (Barrett's esophagus)
  • Undergoing radiation treatment to the chest or upper abdomen
  • Smoking
