I had a similar diagnosis. A cyst on my pancreas. Not cancerous at the time, but the size and location of the cyst was determined to be pre-cancerous. In 2021, I was 69 at the time, in relatively good health. Active. I decided to move forward with the mini-Whipple surgery. With the mini-Whipple, no removal of any of the stomach. I'm not going to lie, the Whipple is no joke. An incision in my mid section, approximately 10 inches long. I was in the hospital for 5 days. Recovery was slow. Eating was a challenge for a while. However, I am glad I had the surgery to circumvent the possibility of developing pancreatic cancer. 2 years after the sugery I was diagnosed Type3C diabetes. I have to take Creon and insulin with every meal. Another set of challenges to manage, but still not pancreatic cancer. You are young, at 56, no one can tell you what to do, they can only tell you of their experiences. Good luck and better health with your decision.
