Consider that you now have a number of holes through your rectum wall that need to heal. I was told to avoid aspirin completely if possible during the biopsy & surgery recovery periods. Since I don't take many as it is, I can't compare to a daily routine.
I was taken off fish oil for that entire period.
Post-biopsy, my "fluids" looked like dirty motor oil for weeks.
As always, consult with the doctor.
