Barretts oesophagus

Hello, I had a endoscopy last Monday, and was told i have Barrett's oesophagus, they took a dozen biopsies.

I was not given any information about this, so i did research as never heard of this before. Previous endoscopy did show a hiatus hernia.

Im still trying to get my head around all this and i don't really want to worry anyone until i know what i am dealing with.

How long do the biopsy results take to come back ?

Any advice please would be so greatful

Thank you
