Esophageal Cancer: Two types of tumors affect the esophagus: squamous cell carcinoma and adenocarcinoma. Symptoms of esophageal cancer include difficulty swallowing (dysphagia), weight loss, central chest pain, pain upon swallowing, vomiting, chronic cough, and symptoms of gastrointestinal bleeding. Esophageal cancer is treated by surgery, chemotherapy, and radiation.
