Hi whatamess
My late father developed cancer (a very long time ago) and on reflection his symptoms were very similar to those described in association with barrets esophagous.
I have recently been prompted to do some research on the subject as a very close friend has GERD symptoms and of course I am frightened for him as I remember my father's illness and how the health professionals at that time failed to offer him any help.
Anyhow, after doing some surfing I came across some great info on GERD/Barretts and the like and have snagged a summary which kind of echoes remarks by previous posters in that your mum needs regular checks on this. Try not to be alarmed by the phrase "precancerous" but do take it seriously and take heart from Katie G's story.

Summary as follows:
Barrett's esophagus is a condition that may develop as a result of chronic GERD. Barrett's tissue growing in the esophagus appears to be the body's defense against continued stomach acid irritation. Yet, this tissue does not belong in the esophagus, and for some patients, it increases the risk of developing cancer. While treatment does not reverse Barrett's, the likelihood of developing cancer and complications can probably be reduced with a combination of diet, lifestyle changes, medication, and/or surgery. A regular program of endoscopic examination and biopsy is essential to monitor the Barrett's tissue. By working closely with a physician, patients can expect good control of both GERD and Barrett's, and an excellent long-term outcome.
