I just want to put out a second perspective on this. Father died of cancer 10 years back. Was a very healthy guy. Because he took very good care of himself – exercise/weight training/eating right/low alcohol intake, he was able to walk/do things up until the night he passed. It probably prolonged it, but he didnt spend weeks/months suffering in a bed. Idk, idk what the best way to live life is. I mostly lean towards do whatever the fuck makes you happy/enjoy the journey because you may not make it to the end of whatever journey you are on anyways.
