Biopsy on your Liver? Doesn't sound fun.
I had my gallbladder removed when I was 14. That was when they still cut you open and used their hands to remove it. Actually they opened me twice. They opened me once to remove the stones from the gallbladder, and then again 4-5 weeks later when I formed new stones. The second time, they decided just to remove the gallbladder altogether. It really sucked!
These days they just remove it through your belly button. I have a super scar that stretches across my whole abdomen, and my solar plexus muscles are deformed because of their faulty handy work. I guess they never heard the camping phrase, leave things nicer than when you arrived.
Best of luck on that biopsy. I am extremely confident that the procedure is technologically advanced such that pain or "discomfort" is at a minimum.
Take care,
