Hello and thank you for posting.

I am afraid I do not know why your doctor wanted you to have a pan endoscopy. It may be that they wanted to examine the area more closely.

It doesn't necessarily mean you have cancer, it is more so that they can work out why you are having the symptoms that you are having.

Take care and I hope you get more information soon.

Sarah.

Thank you so much for your thoughts. 
Best regards . x
