your question can be found at the end of a thread you started a week or so ago called "can you have a lifetime of barretts and no cancer"
as was said above no on can say for sure the outcome for any individual
but the statistics for the overall population...or odds...as you asked for above, are known to a moderate degree of confidence
barretts has stages of cell variation... or a progression... as it is sometimes called, which describe cell changes, when, and if ,there is a progression to cancer
non-dysplastic ( which i believe is also called metaplasia)...where it is estimate that less than one percent of patients see a progression from metaplasia to cancer in any one year
for high-grade dysplasia,... there is a riisk of developing to cancer at a rate estimated at around 10% per patient each year.
there is excellent information about
this in the wikipedia entry "barretts esophagus"
so if i am diagnosed with a low grade dysplasia i would want to get scoped every year
if i am diagnosed with a high grade dysplasia i would want to receive ablation therapy to eradicate the barretts cells an then go for surgery
this approach should stack the odds very much in favor of survival
there are no sure things
note i was diagnosed with barretts metaplasia last march and i think i share your feelings...i have other medical and emotional issues and swim in a sea of apprehension...or worse
