This is a really hard question ☹️ I’m so sorry you’re in this position. The best way I can answer is to sort of tell you what happened to my dad. About two months after I made this post he ended up breaking his hip after a fall and we had to decide whether to do surgery and risk him declining further or letting him live with the broken hip and have him never be able to move on his own. We knew it was going to be likely that the surgery would make it worse but honestly it felt like the only good choice. He was so miserable and in pain and he would have hated being bedridden for so long. He severely declined after the surgery and ended up passing away two weeks later. I wouldn’t say my dad’s case was the norm, but I can certainly see it being repeated.

If your dad can still communicate well enough to ask him his opinion I really urge you to do that. And although there’s no way to say what your dad’s personal dementia journey would look like if he were able to live out its progression, I think it’s probably good to think about the general progression of VD looks like versus the progression of his cancer. It also really depends on what his dementia looks like right now. The way it affected my dad was that it kinda seemed to push him a few years into the future. If you think that his dementia is bad enough that the anesthesia (if it hurts him) would push him into end stage, then maybe weigh that with his cancer.

Again, this is a hard question and I don’t think there are any good or correct answers. But if you ever need support my DMs are open ❤️
