Australian Barrett's Cohort With Dysplasia and Early Cancer Study

This is a long-term observational study — not a treatment trial — that follows patients across Australia who have Barrett's esophagus (a condition where the lining of the food pipe changes due to acid reflux, increasing the risk of esophageal cancer) with dysplasia (pre-cancerous cell changes) or early-stage esophageal cancer. The study tracks how the condition progresses, how it responds to treatment, and what factors affect outcomes over many years. **You may be eligible if...** - You are over 18 years old - You have been diagnosed with Barrett's esophagus (a change in the lining of the food pipe that raises cancer risk) - You are able and willing to give informed consent to participate in the study **You may NOT be eligible if...** - You are under 18 years of age - You are currently pregnant Talk to your doctor to see if this trial is right for you.
