LOS ANGELES (KDKA/ AP) — Angelina Jolie says that she has had a preventive double mastectomy after learning she carried a gene that made it extremely likely she would get breast cancer.

The Oscar-winning actress and partner to Brad Pitt made the announcement in the form of an op-ed she authored for Tuesday’s New York Times under the headline, “My Medical Choice.” She writes that between early February and late April she completed three months of surgical procedures to remove both breasts.

Jolie, 37, writes that she made the choice with thoughts of her six children after watching her own mother, actress Marcheline Bertrand, die too young from cancer.

“My mother fought cancer for almost a decade and died at 56,” Jolie writes. “She held out long enough to meet the first of her grandchildren and to hold them in her arms. But my other children will never have the chance to know her and experience how loving and gracious she was.”

She writes that, “They have asked if the same could happen to me.”

Jolie said that after genetic testing she learned she carries the “faulty” BRCA1 gene and had an 87 percent chance of getting the disease herself.

She said she has kept the process private so far, but wrote about it with hopes of helping other women.

“I wanted to write this to tell other women that the decision to have a mastectomy was not easy. But it is one I am very happy that I made,” Jolie writes. “My chances of developing breast cancer have dropped from 87 percent to under 5 percent. I can tell my children that they don’t need to fear they will lose me to breast cancer.”

Phone and email messages left by The Associated Press late Monday night seeking comment from Jolie representatives were not immediately returned.

She is anything but private in the details she provides, giving a description of the procedures.

“My own process began on Feb. 2 with a procedure known as a ‘nipple delay,'” she writes, “which rules out disease in the breast ducts behind the nipple and draws extra blood flow to the area.”

She then describes the major surgery two weeks later where breast tissue was removed, saying it felt “like a scene out of a science-fiction film,” then writes that nine weeks later she had a third surgery to reconstruct the breasts and receive implants.”

Many women have chosen preventive mastectomy since genetic screening for breast cancer was developed, but the move and public announcement is unprecedented from a star so young and widely known as Jolie.

She briefly addresses the effects of the surgery on the idealized sexuality and iconic womanhood that have fueled her fame.

“I do not feel any less of a woman,” Jolie writes. “I feel empowered that I made a strong choice that in no way diminishes my femininity.”

She also wrote that Brad Pitt, her partner of eight years, was at the Pink Lotus Breast Center in Southern California for “every minute of the surgeries.”

Bertrand, Jolie’s mother, died in January 2007. She had small roles in the movies “Lookin’ to Get Out” in 1982 and “The Man Who Loved Women” in 1983. She raised Jolie and her brother after divorcing their father, Oscar-winning actor Jon Voight, when Jolie was a toddler.

“In the article she was saying she wanted to get the word out there, let women know they have options and there are things that they can do – and that was exactly the way I felt,” says Laura Sago of Scott Township.

Sago has a similar story.

“My mother had breast cancer at the age of 38, and then a recurrence in her 40s. My sister was diagnosed four years ago with breast cancer and my other sister was diagnosed two years ago.”

With that family history Sago decided on a double mastectomy last September.

She does not regret it.

“What are my risks? How do I find out what my risks are? And then let me know what my options are.” Dr. Thomas Julian has had that conversation with countless worried women. He says many high risk patients do opt for surgery, but others lessen their risks with medication.

Genetic testing is expensive — about $3,000.

“Fortunately, for most individuals who are high risk, where all the guidelines are fulfilled, the insurance carriers will pay for it,” Sago said.

If not, women must pay out-of-pocket for peace of mind.

In the end the decision is hers alone.

“That’s what she has to do on a day to day basis just to be able to get up in the morning and say, ‘Ah, life is going to be good for me,’” she said.

It’s been nearly 20 years since I had my breast cancer surgery.

In that time treatment has become far more personalized.

For women worried about their genetic history, like Angelina Jolie – there is now genetic counseling to help decide what their next step should be.

Jolie has appeared in dozens of films including 2010’s “The Tourist” and “Salt,” the “Tomb Raider” films, and 1999’s “Girl, Interrupted,” for which she won an Academy Award.

But she has appeared more often in the news in recent years for her power coupling with Pitt and her charitable work with refugees as a United Nations ambassador.
