CAT Scan....
Hell of a lot of fun. I hate the dye they inject you with before you get run through the donut hole. Give you a warm feeling and makes you feel like you pissed yourself. Good thing is it passes quick and the test is over. Better than an MRI that takes 30 to 60 min in that little tube with all that damn banging. Good luck with your test and surgery to remove it. Like been said don't pick anything up and you will be fine.
