What is esophageal cancer?

ANSWER

Esophageal cancer is when cancer cells develop in the tube-like structure that runs from your throat to your stomach. There are two main types:

By the time esophageal cancer is diagnosed for many people, it's often already in an advanced stage, where it has spread throughout the esophagus and beyond.

  • Squamous cell carcinoma develops in the cells that line the entire length of the inner esophagus.
  • Adenocarcinoma develops from gland cells that replace squamous cells. It's believed to be largely related to stomach acid exposure in the lower esophagus.
