Esophageal cancer may be totally asymptomatic in the early stages or may present with nonspecific complaints that may include heartburn, atypical chest pain, or dyspepsia. Patients may, on the other hand, present with occult blood in the stool or anemia. Other presenting symptoms may include dysphagia (difficulty swallowing), weight loss, or odynaphagia (pain on swallowing). Patients may complain of excessive salivation, hoarseness or pulmonary symptoms such as recurrent infections. Later in the disease course the patient may vomit blood from an oozing esophageal tumor or tumor erosion into a vessel.
