what organ grows back once removed
Kat - It will grow back. The liver will actually grow back a couple of weeks after removing it. It's really phenomenal. In the case of cancer patients you can remove 50-60% of someone's liver and it will grow back.
A Discovery Health answered. The liver is the only organ in the body that can grow cells and regenerate itself. It can actually be split in half and transplanted into two different recipients. A living personal also can have a portion of his or her liver removed, and the portion that remains will regenerate itself to nearly its original size.
