Human: I'm trying to find out what a hysterectomy is and what it does. Assistant: 
A Hysterectomy is the surgical removal of the uterus, which is the organ that contains a woman's eggs and her fetus during pregnancy. It is usually performed to treat uterine cancer or fibroids, but can also be done for other medical reasons. The procedure involves removing the uterus through an incision in the abdomen. After the surgery, the patient will have no more menstrual periods, though they may still ovulate.
