Hi Azu,
No one on this site can dispense medical advice, but we can share our own experiences.

You certainly have a lot going on, medically. I can’t speak to the cancer issue, but as to the Eliquis…. it’s important to gauge your stroke risk. Do you know your CHA2DS2-VASc score?
How long has it been since your ablation? Are you being monitored for any arrhythmias?

My EP green lighted my going off Eliquis despite the fact I am female, have a score of “2” and had several instances of non-sustained arrhythmias several months post-RF catheter ablation for AF. (I have an implantable loop monitor is why.) I too was initially hesitant about stopping the Eliquis cold turkey, concerned about an increased risk of stroke. My EP felt that was not a real issue for me. But this needs to be a frank discussion between you and your EP, with input from your oncologist. It’s never a good idea to peremptorily discontinue a medication without proper oversight.
You may be creating a whole host of new problems for yourself!
