Esophageal Cancer Types
- Esophageal squamous-cell carcinoma –It is formed by epithelial cells that line the esophagus. It is mostly caused by the use of alcohol, betel nuts, cigarettes, and a bad diet.
- Esophageal Adenocarcinoma – This kind of esophageal cancer develops from glandular cells in the bottom portion of the esophagus. Tobacco usage, obesity, and acid reflux are all risk factors for this kind of cancer.
Small cell carcinoma, sarcoma, lymphoma, melanoma, and choriocarcinoma are all rare kinds of esophageal cancer.
Esophageal Cancer Stages
Esophageal cancer stages aid in assessing the extent and size of cancer, the extent of tumor invasion, lymph node involvement, and distant metastases. Doctors utilize a variety of staging systems to define esophageal cancer stages, and this staging method also helps them decide on the best course of therapy for the patient.
The esophageal cancer stages are divided into four categories, with stage 0 indicating that the disease is restricted to the superficial layer of the esophagus and stage IV showing that cancer has spread to other parts of the body.
