Hello @lynn2106 and welcome to Mayo Clinic Connect. I can understand your concern about these recently found pancreatic cysts, especially given your mother's history with pancreatic cancer. My pancreatic cysts were found over 15 years ago. I had a similar anxiety response, as I have a history of a rare form of cancer in the duodendal bulb (near the pancreatic bile duct). I also had an EUS, which showed an IPMN, and I was told "not to worry." That turned out to be good advice, as the cysts have remained the same over the years. I have three cysts that have remained the same, and a few smaller cystic lesions that are also unchanged. Here is some information about size and location from my last MRI report:
pancreatic neck, 0.5 cm, unchanged
pancreatic body, 0.8 cm, unchanged
pancreatic body, 0.9 cm, unchanged
A few smaller cystic lesions are unchanged. No internal nodular enhancement.

As in your experience, the first evidence of these cysts was on a CT scan for an unrelated matter. The first few years after the original CT scan, I had MRIs every year. The follow-up is now every other year.

If you are at all unsure about this diagnosis, I suggest you seek a second opinion from a doctor affiliated with a Pancreatic Center of Excellence. Mayo Clinic is one such facility (here is a link with appointment information: http://mayocl.in/1mtmR63.). If an appointment at Mayo is not possible, search for another major medical center in your area, such as a university medical school, or you can contact the National Pancreas Foundation. Here is their website, https://pancreasfoundation.org/patient-resources/npf-centers-of-excellence/.

The important thing is to be proactive so you can worry less and ensure appropriate follow-ups. Does this sound like a good plan? Have you had blood work to determine pancreatic functioning?
