Cancer of the esophagus is a
tumor that begins its growth in
the lining of the esophagus. It
can then grow through the wall
of the esophagus, and can spread
to other parts of the body through
the blood or the lymphatic system.
Studies show a relationship
between frequency of reflux symptoms
and risk of esophageal cancer.
The constant acid reflux will
irritate the lining of the esophagus,
and complications can occur, such
as Barrett's esophagus. Individuals
with Barrett's esophagus are about
40 times more likely to develop
esophageal cancer than individuals
in the general population.
