@hope222222, what a miracle that they found the tumor on the pancreas early and while it is small and that no other organs appear to be involved. To learn more about what to expect from a distal pancreatectomy, you may wish to visit the discussions in the Pancreatic Cancer group. I know that your husband's lesion is metastatic colon cancer, but the surgical experience will be similar. See the discussions here:

You're in good hands at Mayo. When will he have surgery?
