Q

How does it present?

A

Dysphagia (any new symptoms of dysphagia, especially over the age of 45, should be assumed to be cancer until proven otherwise).

Haematemesis, rarely the presenting symptom. Incidental screening, when following up Barrett’s metaplasia, achalasia or reflux disease.

Symptoms of disseminated disease. Cervical lymphadenopathy, hepatomegaly due to mets etc.

Symptoms of local invasion, dysphonia, cough and haemoptysis, neck swelling, horners syndrome.
