Cancer is so variable. A friend of ours realised they were ill because their half-marathon time (which would have had a heart attack trying to hit) was way worse than expected. He was dead about two months later. Like your freind he went from looking "a bit peeky" but still going on cycle rides, to being barely able to talk in the space of a few weeks.
He and his wife are planning all the things they would do in early retirement. His death taught me an important lesson about not waiting too long to do the things you really want to do with the people you really want to be with.
Another of my wife's friend has been suffering from a cancer that was expected to kill her about two years ago but she just keeps going and surprising everyone. Cancer can be so damn capricious.
Not sure if involved. But Medication can wipe a person out. I’ve been on a few (not cancer) that left me in bed barely able to speak for weeks on end. Skip a couple doses and I’m about and fine.
