Same here - but mine was in lower 3 inches of esophagus from long-term acid reflux - and I didn’t want the surgery where they remove the whole esophagus and then use most of your stomach to “form a new one”.
So far, so good - clean PET Scans for last 9 months - with a gastro guy going in and taking biopsies and doing ablations to help remove any possible recurrence areas.
stay well
