Angelina Jolie made the difficult choice of having her breasts, ovaries and fallopian tubes removed because genetic tests showed, without the elective surgery, she had an 87 percent chance of getting breast cancer and a 50 percent chance of developing ovarian cancer.

Jolie's mother died at 56 years old. She also lost her grandmother and aunt to cancer. In a New York Times op-ed the filmmaker and actress explained why she made that decision.

Watch this video to find out what it is and how it works.
