Well I'm sure if you read anything about celebrities that you've heard about Angelina's preventative surgeries that she's had which include, a double mastectomy, and a removal of her ovaries. This was all after finding signs of possibly having cancer in her future.
This is one of the reasons it's extremely important to stay ahead of the game and have constant knowledge of the health information on you that your doctors have. This way you can make decisions as necessary just as Jolie Pitts did. Good luck to her and I hope her health stays good.
