Have a read of the Barretts thread I started - I'll bump it up for you. The thread got somewhat hijacked further down and needs a revamp, but the take home points remain the same. The risk of progression is very low, and when you look at the study reporting deaths from ALL causes, the highest cause of death in those with Barretts is heart disease, and not any kind of cancer!
I have Barretts too, very small area and it's stayed the same over 3 years. I try to think that at least we are the ones who will get checked up on - there are plenty of folk out there who don't know they've even got it and so won't get scoped. And there are cases of adenocarcinoma without Barretts, so much is not yet understood.
I work in a department supporting people with cancer (just admin myself) and I agree it is hard not to get scared when you see the reality of it all the time but you have to focus on ways of keeping perspective. For me, I ask myself, aside from the forum, how many people do I know who have Barretts, or who even have GERD? In answer, I know one or two people on PPIs, who are VERY well, and I know a lot of people with OTHER cancers! That, helps me keep a balanced view, of sorts: I'm far more worried about breast cancer than I am about the Barretts!!
GERD (over 2 years)
Lifelong stuff: Food allergies/intolerance, eczema, asthma
