Can GERD be chronic and not turn into cancer?

I’m super scared at the moment, I’ve had GERD on and off for 10 years but lately, it’s constant.
I’m on 10mg of losec, just eradicated H Pylori and have a Gastroscopy in 2 weeks.
The losec isn’t working, and the heartburn is going into my back, my stomach is also sore, it feels like it’s bruised and I’m terrified I might have some form of cancer somewhere in my body as it’s not like me to be constantly in pain from GERD.
Has anyone here had on-going issues for years with GERD and been ok, will it always go to cancer?
I’ve quit coffee, but I did eat some cheese and crackers today whilst sitting in bed and that seemed to have bought it on but seriously is that how sensitive I am now I can’t even eat sitting down?
Im tired and just feel like crying, I’m over not being able to eat and I have to wait 2 weeks to find out way. Anyone relate??
