One of the defining moments in the history of breast cancer occurred in 1974 when the first lady, Betty Ford, spoke openly about her mastectomy, lifting a veil of secrecy from the disease and ushering in a new era of breast cancer awareness.
Now four decades later, another leading lady — the actress Angelina
Jolie — has focused public attention on breast cancer again, but this
time with an even bolder message: A woman at genetic risk should feel
empowered to remove both breasts as a way to prevent the disease. Ms.
Jolie revealed on Tuesday that because she carries a cancer-causing
mutation, she has had a double mastectomy.
“She’s the biggest name of all, and I think given her prominence and her
visibility not only as a famous person but also a beautiful actress,
it’s going to carry a lot of weight for women,” said Barron H. Lerner, a
medical historian and the author of “The Breast Cancer Wars.”
Breast cancer experts and advocates applauded the manner in which Ms.
Jolie explored her options and made informed decisions, saying it might
influence some women with strong family histories of breast cancer to
get genetic tests.
But some doctors also expressed worry that her disclosure could be
misinterpreted by other women, fueling the trend toward mastectomies
that are not medically necessary for many early-stage breast cancers. In
recent years, doctors have reported a virtual epidemic of preventive
mastectomies among women who have cancer in one breast and decide to
remove the healthy one as well, even though they do not have genetic
mutations that increase their risk and their odds of a second breast
cancer are very low.
Ms. Jolie wrote on the Op-Ed page of The New York Times that she had tested positive for a genetic mutation known as BRCA1,
which left her with an exceedingly high risk for developing breast and
ovarian cancer. Her mother died at 56 after nearly a decade with cancer,
though Ms. Jolie did not specify which type. After genetic counseling,
Ms. Jolie opted to have both breasts removed and to undergo
reconstructive surgery.
Ms. Jolie, 37, who declined to be interviewed for this article, was
treated at the Pink Lotus Breast Center in Beverly Hills, Calif., a
clinic opened in 2009 by Dr. Kristi Funk, identified on its Web site as a
former director of patient education at the breast center at
Cedars-Sinai Medical Center in Los Angeles.
Her condition is rare. Mutations in BRCA1 and another gene called BRCA2
are estimated to cause only 5 percent to 10 percent of breast cancers
and 10 percent to 15 percent of ovarian cancers among white women in the
United States. The mutations are found in other racial and ethnic
groups as well, but it is not known how common they are.
About 30 percent of women who are found to have BRCA mutations choose
preventive mastectomies, said Dr. Kenneth Offit, chief of clinical
genetics at Memorial Sloan-Kettering Cancer Center in New York. Those
who have seen family members die young from the disease are most likely
to opt for the surgery.
“It’s important to make it clear that a BRCA mutation is a special,
high-risk situation,” said Dr. Monica Morrow, chief of the breast
service at Sloan-Kettering. For women at very high risk, preventive
mastectomy makes sense, but few women fall into that category, she said.
For women’s health advocates, the trend toward double mastectomies in
women who do not have mutations is frustrating. Studies in the 1970s and
1980s proved that for many patients, lumpectomy was as safe as
mastectomy, and the findings were seen as a victory for women.
Even so, there is increasing demand for mastectomy. Dr. Morrow says that
she has often tried to talk patients out of it without success. Some
imagine their risk of new or recurring cancer to be far higher than it
really is. Others think that their breasts will match up better if both
are removed and reconstructed.
Ms. Jolie’s decision highlights the painful dilemma facing women with BRCA mutations.
“She is a special case, and you can completely understand why she did
it,” said Dr. Susan Love, the author of a best-seller, “Dr. Susan Love’s
Breast Book,” and a breast surgeon. “But what I hope that people
realize is that we really don’t have good prevention for breast cancer.
When you have to cut off normal body parts to prevent a disease, that’s
really pretty barbaric when you think about it.”
Women who carry BRCA mutations have, on average, about a 65 percent risk
of eventually developing breast cancer, as opposed to a risk of about
12 percent for most women. For some mutation carriers, the risk may be
higher; Ms. Jolie wrote that the estimate for her was 87 percent.
Because the BRCA mutations are rare and the test expensive — about $3,000 — it is not recommended for most women.
But for women with breast cancer who do have mutations, knowing their
status can help them make further treatment decisions, like whether to
have an unaffected breast or their ovaries removed.
Women who should consider testing are those who have breast cancer
before age 50, a family history of both breast and ovarian cancer, or
many close relatives with breast cancer, especially if it developed
before age 50. Any woman with ovarian cancer should consider being
tested, as should Ashkenazi Jewish women with breast or ovarian cancer.
Men with breast cancer and their families should also ask about the
possibility of a genetic predisposition to the disease.
Because the cancer risks for carriers are so high, women with the
mutations are often advised to have their breasts and ovaries removed as
a preventive measure. It is generally considered safe to wait long
enough to have children before having the ovaries removed, but the
operation should be done by age 40, said Dr. Susan M. Domchek, an expert
on cancer genetics at the University of Pennsylvania and the executive
director of its Basser Research Center,
which specializes in BRCA mutations. There is no reliable way to screen
for ovarian cancer, and most cases are detected at a relatively late
stage, when the disease is harder to treat and more likely to be fatal.
Ms. Jolie said that she herself had a 50 percent risk of ovarian cancer.
“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,” she wrote.
Removing the breasts is not the only option, Dr. Domchek said. Some
women with BRCA mutations choose close monitoring with mammograms and
M.R.I. scans once a year, staggered so that they have one scan or the
other every six months. Those tests offer a chance to find cancer early.
For some women, certain drugs can lower the risk of breast cancer, but not as much as preventive mastectomy.
It is also possible for women who are mutation carriers to avoid passing
the gene to their children, by undergoing in vitro fertilization and
having embryos screened for BRCA genes. Then, only embryos free of
mutations can be implanted.
Ms. Jolie’s celebrity and her roles as a mother of six and a movie star
who plays strong women, including the swashbuckling archaeologist Lara
Croft, may give her decision far-reaching impact.
Dr. Isabelle Bedrosian, a surgical oncologist at M. D. Anderson Cancer
Center in Houston, has been a vocal critic of the trend toward double
mastectomy among women who are not at high genetic risk. However, she
hopes the decision by Ms. Jolie will focus women on the value of genetic
counseling and making informed decisions.
“I think there is an important upside to the story, and that is that
women will hopefully be more curious about their family history,” Dr.
Bedrosian said. “We need to be careful that one message does not apply
to all. Angelina’s situation is very unique. People should not be quick
to say ‘I should do like she did,’ because you may not be like her.”
