Hi there -
I must say a few things from personal experience:
1) Genetics are important - there may or may not be markers for this.
2) Don't let a doctor give you statistics - or you might become one.
3) You may need to be scoped every 6 months or a year - no longer!
4) If your doctor does not agree with #3 above, find another one.
5) Go to a center of excellence, where there is a specialist in Esophageal Disorders.
No need at all to panic.
