The information below is intended to provide you with a general understanding of the progression of Barrett's esophagus to cancer. Refer to a medical professional for more detailed information and to address any questions you may have.
|1.||Intestinal metaplasia (IM) - The tissue cells have begun to change genetically and the tissue resembles the red intestinal lining rather than the normal and healthy pink esophagus lining. At this stage, a person has Barrett’s esophagus, but has not developed Dysplasia, the next stage.|
|2.||Low-grade Dysplasia (LGD IM) – Less than 50% of the abnormal cells have begun to change in size, shape, or organization and may show an increase in their growth rate. The cells are contained within the lining of the esophagus and have not spread to other areas.|
|3.||High-grade Dysplasia (HGD IM) – As with LGD, the abnormal cells reside within the lining of the esophagus. But more than 50% of these cells do demonstrate a higher increase in abnormal growth rate and pattern.|
|4.|| Adenocarcinoma (Esophageal
Cancer): When the abnormal cells have a rapid and uncontrolled
growth rate. The cells also invade the deeper layers of your esophagus and
may spread beyond that. These cells can develop into malignant tumors.
Adenocarcinoma can also be classified in different stages or categories.
