I'm so sorry about hearing this. Ask about doing an "EGD" esophagogastroduodenoscopy. It's done in humans as well as animals. It's a tube put down the mouth to the beginning of the duodenum. You're going to need a specialist to perform it and the tumor can be removed that way. It may be a polyp.
The dog is sedated of course for this procedure and there is little discomfort.
Please ask the vet about this.
Keep us posted.

Fingers crossed that it's benign. We're all anxious with you
