Lower esophageal sphincter cancer is a type of cancer that affects the lower esophageal sphincter (LES), which is a ring of muscle at the bottom of the esophagus where it meets the stomach. The LES acts as a gatekeeper, preventing stomach acid from flowing back into the esophagus. When cancer forms in this area, it can disrupt normal digestion and lead to serious health issues.
Types of Lower Esophageal Sphincter Cancer
- Adenocarcinoma: The most common type, originating in the glandular cells of the esophagus.
- Squamous Cell Carcinoma: Arises from the flat cells lining the esophagus.
- Small Cell Carcinoma: A rare form that grows quickly and is usually diagnosed at an advanced stage.
- Neuroendocrine Tumors: Tumors that start in hormone-producing cells in the esophagus.
- Sarcomas: Rare cancers that begin in the connective tissues of the esophagus.
- Mixed Histology Tumors: Tumors that have characteristics of more than one type of cancer.
- Barrett’s Esophagus Cancer: Cancer that develops in the abnormal cells caused by Barrett’s esophagus, a condition often related to chronic acid reflux.
- Lymphoma: Cancer of the lymphatic system that can occasionally involve the esophagus.
- Melanoma: A rare type of cancer that can spread to the esophagus from other parts of the body.
- Secondary Esophageal Cancer: Cancer that has spread to the esophagus from another organ.
