Texas researchers are trying to determine whether patients can use an abortion pill to stop the growth of uterine cancer or keep it from coming back, RTV6's Stacia Matthews.

Surgery and radiation can help get rid of uterine cancer, but women at high risk of having the cancer return could benefit from taking RU-486, researchers said.

The pill also could help starve existing tumors, they said.

RU-486 is synthetic progesterone. Because certain endometrial cancer cells are estrogen or progesterone receptive, progesterone can lock onto these cells and block estrogen, blocking the cancer or slowing its growth.
