If the surgeon has reviewed your test data and feels you are a candidate for Whipple surgery, it usually means the opinion is they can completely remove the tumor. Whipple surgery is the only curative treatment for PC. If they are offering surgery, they are offering a chance for a cure.
I had the surgery at age 50, a little over five years ago. It is tough, it takes time to recover and as many people on this board have pointed out, you won't ever get back to what was "normal" when you were healthy. I have good quality of life, eat almost anything I want without problems, walk between 4-5 miles every morning and enjoy staying busy in my gardens.
Surgery of any type is frightening but try not to let fear affect your decision. Whipple is one of the most serious surgeries out there. Your age, and the fact you say you are otherwise healthy are in your favor.
Best wishes for good results.
