I am now 63 years old. I had a well differentiated, grade 1, stage 1 gastrinoma neuroendrocrune 1.5cm tumor in the pancreas head. Whipple surgery done in May 2020. No chemo but was on Creon for 6 to 9 months or so. Chromograni A is considered high, over 600. At times, have diarrhoea; recently has rashes at the back and occasionally heart burnt (just done a CT scan to rule out heart issue & waiting for results). After surgery, eat more frequent small meals, walk regularly to keep fit. I can continue to live normally & continue with hiking.
