Thirst may be an early symptom of esophageal cancer, but it could also result from other factors. Esophageal cancer is a type of malignant tumor that may cause progressive dysphagia, retrosternal pain, and dry mouth in its early stages. However, dry mouth might also be caused by chronic pharyngitis, which may be accompanied by symptoms such as throat swelling and pain.
