Hello, my tumor was discovered by accident while they were checking for kidney stones. My symptom was back pain but I was also having alot of night sweats. No one was really sure if it was a PNET or a exocrine tumor. It was 3cm in size and in the tail. They tried to bx it with an EUS. That doctor said he could not access it with a needle which meant it was most likely a fast growing cancer. The next day I saw a pancreas specialist and she removed the tail of the pancreas containing the tumor and the spleen. The biopsy revealed it was a PNET. I had a long recovery but the peace of mind is 100 percent worth it. So far my blood sugar has remained stable. I do have intermittent issues with digestion, but I would not change my decision for anything. It has been five years. I have yearly blood testing and MRI's with an oncologist.
