8) Hiccups
We have already discussed several reflex systems associated with the esophagus, and hiccups are also one of them. Patients with advanced esophageal cancer would have frequent hiccups combined with the symptoms described above. Hiccups are commonly seen in healthy patients, and there are even diseases featuring chronic hiccups without involving any type of tumor growth. Thus, this symptom is not thought to be the primary warning sign to detect esophageal cancer, and your doctor might need to perform certain imaging diagnostic tests and lab tests to fully understand the root cause of your hiccups in combination with the symptoms we have already described.
