The father of a good friend passed away recently from a brain cancer. He was a doctor, but atypically accepted every treatment available. His last 3 years were spent in surgery or sick from chemo, did not have one good day after his initial diagnosis. If he could have gone back I'm sure he would have decided not to be treated.

Unless going back gets you to re-roll your dice then I'm sure they would still have done it.

You might not want it for yourself but many people, especially health professionals in my experience, will take a smaller but less painful lifespan over a chance to live longer through horrible treatments.
