Hello @caroline24 and welcome to Mayo Connect. I've read your posts and certainly understand your concerns. Any problem with the pancreas always brings worries. I had cysts show up on my pancreas about 15 years ago. I also had a EUS (but no biopsy as it appeared to be benign). I've had follow-up MRIs on a regular basis since then with no changes in size or the number of cysts. They have basically remained the same.

Like you, I was quite worried at the start, but now accepting it as not a great of a threat to my health (or happiness). Perhaps you could ask your GI doctor to do pancreatic blood work. This would show if there are any problems with the functioning of the pancreas.

Here is another discussion on Connect that might help you to understand this better,

Please continue to post about your questions and concerns. Waiting for the EUS and the results can be stressful.
