Types of Esophageal Cancer

In 2013, about 18,000 Americans will be diagnosed with esophageal cancer.

The two most common types are named for how the cancer cells look under a microscope:

  • AC: About 12,000 Americans will be diagnosed with AC (adenocarcinoma) of the esophagus in 2013. In the United States, AC is the most common type of esophageal cancer. Usually, AC tumors are found in the lower part of the esophagus, near the stomach. AC of the esophagus may be related to having acid reflux (the backward flow of stomach acid), having a disease of the lower esophagus known as Barrett esophagus, or being obese.
  • SCC: About 6,000 Americans will be diagnosed with SCC (squamous cell carcinoma) of the esophagus in 2013. In other parts of the world, SCC is the most common type of esophageal cancer. Usually, SCC tumors are found in the upper part of the esophagus. SCC of the esophagus may be related to being a heavy drinker of alcohol or smoking tobacco.
