Scared i have esophageal cancer

I wanted to reach out and receive some opinions/assurance on a couple issues that I am having and see if you can alleviate some of my concerns. My son is a 29 year old male, average build. Does not smoke or chew but do drink alcohol.

I have reason to believe that he might have esophageal cancer. And the reason that I say that is because in December of last year, he had an episode in which he tried to swallow a mouthful of food and it just got stuck in the back of my throat.

He tried to wash it down with some water and the water basically pooled on top of the food and didn’t allow for the food to pass. Eventually he have to throw the food back up. Now since then. there has been 3-4 instances in which the same thing has happened to him. Although these instances were not as severe as the first time (He didn’t have to vomit the unregurgitated food), I did find it to be weird.

Fast forward to today, he haven’t had any issues with the swallowing of food, but I’m not convinced that it won’t happen again. In addition to the issue with the food swallowing issue, he just got over a cold in which there was a cough. The cough has not gone completely away and it’s not a consistent cough.

He also have a slight pain in my back in-between my shoulder blades, not sure if that is a cause of the possible cancer or if it is an issue of poor posture.

Any help would be great, I am very scared and don’t know what to do. He is scheduled for an upper endoscopy next Monday, but I’m scared and would like a little reassurance.
