Angelina Jolie made the decision to have both of her breasts removed despite being healthy.
This came on heels of finding out that she has the BRCA1 cancer gene, giving her an 87 per cent chance of developing breast cancer and 50 per cent risk of ovarian cancer.
Her mom Marcheline Bertrand died in 2007 after battling ovarian cancer.
In her intevriew with the New York Times, the 37-year-old actress said, “My doctors estimated that I had an 87 percent risk of breast cancer and a 50 percent risk of ovarian cancer, although the risk is different in the case of each woman.
"Only a fraction of breast cancers result from an inherited gene mutation.
"Those with a defect in BRCA1 have a 65 percent risk of getting it, on average.
"Once I knew that this was my reality, I decided to be proactive and to minimize the risk as much I could.
"I made a decision to have a preventive double mastectomy."
MayoClinic.com defined mastectomy as a "surgery to remove all breast tissue from a breast as a way to treat or prevent breast cancer."
Angelina resumed, "I started with the breasts, as my risk of breast cancer is higher than my risk of ovarian cancer, and the surgery is more complex.
“On April 27, I finished the three months of medical procedures that the mastectomies involved.
"During that time I have been able to keep this private and to carry on with my work.”
Angelina’s surgery was a success and the doctors say her chances of developing breast cancer are now less than five per cent.
The mother of five— Maddox, 11, Pax, 9, Zahara, 8, Shiloh, 6, and four-year-old twins Knox and Vivienne with fiance Brad Pitt— thanked her husband for helping her through the treatment.
She added, “I can tell my children that they don’t need to fear they will lose me to breast cancer.
“It is reassuring that they see nothing that makes them uncomfortable. They can see my small scars and that’s it. Everything else is just Mommy, the same as she always was.
“I am fortunate to have a partner, Brad Pitt, who is so loving and supportive. So to anyone who has a wife or girlfriend going through this, know that you are a very important part of the transition.
"Brad was at the Pink Lotus Breast Center, where I was treated, for every minute of the surgeries.
"We managed to find moments to laugh together. We knew this was the right thing to do for our family and that it would bring us closer. And it has.”
