Here is info from the web:

[The Barrett's cells may develop abnormal changes known as dysplasia. Over a period of perhaps two to five years, the dysplasia may then progress to low grade, then to high grade dysplasia, and finally to cancer. Fortunately, this happens only in about 1-5% of patients with Barrett's esophagus.

Diagnosis of Barrett's esophagus requires an examination called upper endoscopy or EGD (esophagogastroduodenoscopy). A barium x-ray is not accurate for detecting Barrett's esophagus. An EGD is done with the patient under sedation. The physician examines the lining of the esophagus and stomach with a thin, lighted, flexible endoscope. Biopsies are performed, taking pieces of tissue to be examined under a microscope for abnormal cells which have the potential of becoming malignant. The changes may be indefinite dysplasia where the pathologist may be uncertain of the changes. In this circumstance, medical treatment is intensified and repeat biopsies are performed in 6-12 months. When dysplasia is definite, some type of definite correction is necessary.]
