I am taking Revlimid and Vidaza and I golf every chance I get. I have zero side effects from the Revlimid. The Vidaza is more noticeable but that might be from the anti-nausea pills. Still not enough to keep from golfing. The more important things as far as activities are the blood counts.
You are not alone in your dislike of cancer. Importantly, try not to let the physical ailments affect you mentally as much as possible. Everyone is going to have life threatening situations in their lives. You just do the best you can to limit the problems for the things you can control. Try not to worry too much about the things you cannot influence.
