The healing process was fairly quick... and, I was left with a barely noticeable dimple-like scar.
Pathology results are usually available within the time frame that you were told... but, sometimes there are slight delays; so, allow for that. As for air travel, I don't see a problem with that... but, you may want to mention it to the doctor who preforms the biopsy. And, you may want to travel light or have someone carry your heavy luggage for you. Good luck with your procedure.
