Barrett's oesophagus--a ray of hope

The incidence of oesophageal cancer at the cardia is believed to be increasing, especially in younger individuals. Although the causes are unknown, Barrett's oesophagus may be such a cause, since it has a proven pre-malignant potential. It is generally believed that long-standing gastro-oesophageal reflux disease predisposes to columnar transformation in the oesophagus, although it is unclear whether medical or surgical treatment has significant effects in the long term.
