I had untreated severe GERD for 8 years. I'm 25 and got it when I was 17. I have a little trouble swallowing which is freaking me out. As in statisctics..

1. How long does it take for GERD to turn into Barretts?

2. How long does it take for Barretts to turn into cancer?

3. From GERD to Barretts and finally cancer..what is the total amount of years?
