Esophageal Adenocarcinoma is a type of cancer that forms in the cells of the esophagus, specifically in the glandular tissue. This cancer often develops in the lower part of the esophagus, where it connects to the stomach. Risk factors include chronic gastroesophageal reflux disease (GERD), obesity, and smoking. Symptoms may include difficulty swallowing, weight loss, and chest pain. Diagnosis typically involves imaging tests and a biopsy. Treatment options often include surgery, radiation therapy, and chemotherapy, depending on the stage of the cancer and the patient's overall health.
