Hi, my father has been diagnosed with early stage pancreatic cancer. He's 80 and fit. He will not respond well to being infirm. Is Whipple's surgery likely to give a good quality of life? Or is forgoing treatment likely to be a better (albeit shorter) option? If post-surgery quality of life is just existing, I believe he'd rather live well for his remaining time rather than simply existing in an extremely compromised state.
