I am glad to hear that you are relatively symptom-free. I also have pancreatic cysts (many of them) and we watch and wait with those. For several years, MRIs and CT scans also showed what was considered an "Indolent lesion" on the liver. My anxiety goes high with reports like this because I have had three surgeries for a rare form of cancer (carcinoids) in the upper digestive tract. Curious thing is, the indolent liver lesion disappeared when I had the MRI last year. Strange, huh?
I note that you mention that you are anemic. Do your doctors know why you are anemic? I have a friend who was very anemic. All of the iron supplements did nothing for the anemia. She had an upper endoscopy and was found to have celiac disease. Have you been checked for celiac? It might be worth talking with the Mayo doctors regarding that. Here is a link to information about celiac disease from Mayo's website, https://www.mayoclinic.org/diseases-conditions/celiac-disease/symptoms-causes/syc-20352220.
I can see your concern about the growth of the lesion, however. Once again, I'm really glad that you are being seen at Mayo tomorrow. I do hope you will report back and let me know how you are doing.
What Mayo department(s) are your appointments tomorrow?
