Yes, they will collapse the lung. That's the only way to get all the instruments in there through those tiny little holes. Several days after the surgery, you will feel and hear crackling sounds when you breathe as the lung fully expands and adheres to the chest wall again. It's kind of weird!

Also, get ready for a cantaloupe sized right breast! I had a ton of swelling and bruising. You may want to wear a bra 24/7 for a while, to support the area.

Good luck!
