Untreated GERD now cancer?

So I basically I think from 2017 have had LPR I am now 19 and therefore it would be roughly 7 or 8 years with LPR/GERD untreated as I didn’t properly notice that I had a problem 🥲

I have just noticed I now am having problems swallowing and am questioning as to whether this may be cancer, or maybe a stricture 🤷‍♀️
