This week actress Angelina Jolie revealed in a New York Times op-ed that she underwent preventive double mastectomy. As would be expected of a personal revelation of such a well-known celebrity, it drew intense media attention. Her disclosure was brave and selfless and may save the lives of women in a similar situation, but is likely to be misunderstood by her myriad fans.

Jolie’s mother died at the age of 56 of cancer. (We are not told what kind of cancer.) This lead Jolie to pursue genetic testing which found that she had a harmful mutation in a gene called BRCA1. This mutation greatly increases her risk of breast and ovarian cancer. It was this finding that led her ultimately to choose preventive double mastectomy in an attempt to minimize her future breast cancer risk. Her description of her decision and ordeal is poignant. If you haven’t, please read it.

In this story of empowerment and survival, where is the potential for misunderstanding? Women are likely to misunderstand two issues – who should seek genetic testing for cancer causing mutations, and who should be considering preventive double mastectomies.

Let’s unpack the decision to get genetic testing first. Mutations in two genes called BRCA1 and BRCA2 are linked with very high risks of breast and ovarian cancer. But these mutations are quite rare in the general population, and these mutations are estimated to be responsible for only 5 to 10% of breast cancers and 10 to 15% of ovarian cancers. So genetic testing is not recommended for everyone. The National Cancer Institute lists the following groups of women as having a higher likelihood of a harmful BRCA1 or BRCA2 mutation.

  • For women who are not of Ashkenazi Jewish descent:
    • two first-degree relatives (mother, daughter, or sister) diagnosed with breast cancer, one of whom was diagnosed at age 50 or younger;
    • three or more first-degree or second-degree (grandmother or aunt) relatives diagnosed with breast cancer regardless of their age at diagnosis;
    • a combination of first- and second-degree relatives diagnosed with breast cancer and ovarian cancer (one cancer type per person);
    • a first-degree relative with cancer diagnosed in both breasts (bilateral breast cancer);
    • a combination of two or more first- or second-degree relatives diagnosed with ovarian cancer regardless of age at diagnosis;
    • a first- or second-degree relative diagnosed with both breast and ovarian cancer regardless of age at diagnosis; and
    • breast cancer diagnosed in a male relative.
  • For women of Ashkenazi Jewish descent:
    • any first-degree relative diagnosed with breast or ovarian cancer; and
    • two second-degree relatives on the same side of the family diagnosed with breast or ovarian cancer.

Women without these family history patterns are very unlikely of having a harmful BRCA1 or BRCA2 mutation. If you believe you might be in one of these groups the best way to get tested is to first consult a geneticist. A geneticist will evaluate your family and personal history and help you select the relevant genetic tests to order.

The other issue that women may misinterpret is Jolie’s decision to have a double mastectomy. This decision is entirely reasonable in a woman with a harmful BRCA1 or BRCA2 mutation, because of her very high lifetime risk of breast cancer. Unfortunately in recent years women have increasingly asked surgeons for mastectomies in situations in which mastectomies are not indicated. In an excellent and sobering article about how the drive to increase breast cancer awareness has unduly frightened hundreds of thousands of women, miscommunicated the benefits of mammograms, and failed to communicate the frequent harms of screening, Peggy Orenstein states that thousands of women consider double mastectomies after being diagnosed with low-grade breast cancer. In most women with localized breast cancer lumpectomies have been proven to be as effective as mastectomy in preventing recurrence, and the risk of breast cancer in the other breast is very low, so the decision to have a double mastectomy is driven purely by fear and a misunderstanding of the risk. It’s also important to know that bilateral mastectomies do not decrease the risk of breast cancer to zero because some breast tissue always remains. So preventive mastectomies are only helpful for women at very high risk of breast cancer, and even for them, preventive surgery isn’t the only option.

So I applaud Ms. Jolie for her courage in telling her story in the hopes that other high-risk women seek genetic counseling. And I hope that her fans understand that her decision and advice do not apply to the vast majority of women who are at average risk of breast cancer.
