I've had various forms of diarrhea for the past two years. I had a Whipple in March, 2025 to remove a pancreatic tumor (T-1, borderline resectable) , and I've been on chemo for most of the time since, owing to elevated CA 19-9 markers. And two months ago, I underwent four sessions of radiation therapy targeting a small liver lesion. I've been tested for infection, etc., with no positive results. This is the most debilitating part of my condition. I'm now searching for a gastroenterologist with experience in treating cancer patients who've had a Whipple, and then a nutritionist, as well. But I'd welcome the suggestions of all in this forum.
