Overview[edit | edit source]
Esophageal cancer may be classified into squamous cell carcinoma or adenocarcinoma based on histology.
Classification[edit | edit source]
Esophageal cancers are typically carcinomas, which arise from the epithelium, or surface lining of the esophagus. Most esophageal cancers fall into one of two classes according to their histology. [1]
- Squamous cell carcinoma
- Esophageal squamous cell carcinoma are similar to head and neck cancer in their appearance and are associated with smoking and alcohol consumption.
- Adenocarcinoma
- Esophageal adenocarcinomas make up more than 70% of esophageal cancers.
- They are often associated with a history of gastroesophageal reflux disease and Barrett's esophagus.
