FDA will require manufacturers of power morcellators to place “boxed” warnings on their devices. Earlier this year, FDA recommended against the widespread use of the procedure. The new warnings will better inform women that using power morcellators to remove uterine growths may contribute to spreading cancer inside their bodies and decrease the odds of long-term survival.
Power morcellation involves inserting a small electric device into the abdomen and slicing up tissue in order to remove it through a small incision. It has long been used to remove fibroid tumors from the uterus, or to remove the uterus itself, and is far less invasive than traditional abdominal operations.
