A biopsy is a procedure that involves removing and examining a small sample of body tissue to diagnose or evaluate a condition.

Biopsy samples can be taken from almost anywhere on the body and sometimes from deep within the body. It is possible for the biopsy needle to damage other organs during the procedure. This may result in bleeding and can be treated with embolization.
