Sept. 28, 2009 -- In the first study to define how many American women are
undergoing prophylactic mastectomy, researchers have found that the number of
women choosing to have the protective procedure is on the rise.
Prophylactic mastectomy is the removal of a healthy breast in order to
reduce risks of developing breast cancer. According to the study’s
results, the number of patients in New York State who had a healthy breast
removed after a cancer diagnosis more than doubled between 1995 and 2005, even
though the total number of women having mastectomies dropped by
one-third. The rate of women who underwent the procedure without having
any breast cancer at all only rose slightly during this period.
“It’s true that women who decide to have prophylactic mastectomies end up
with a ‘virtually zero’ risk of having breast cancer. But my patients
say, ‘It’s not even the medical issue; it’s the anxiety.’ They just don’t want
to worry about getting it in the other breast some day,” explains breast cancer
surgeon Rache Simmons, MD, FACS, of New York-Presbyterian Hospital/Weill
Cornell Medical Center. “I have never had a patient regret that
decision,” says Simmons, who was not involved in the study.
Simmons estimates that she performs 10 times as many double mastectomies in
patients with one non-cancerous breast than she did 10 years ago. Part of
the reason: the much wider availability and awareness of genetic testing for
the BRCA1 and BRCA2 mutations, she tells WebMD. These gene mutations are
associated with an 85% lifetime risk of developing breast cancer and a much
higher chance of tumors appearing in both breasts, according to the American
Greater social acceptance of double mastectomies and improved cosmetic
surgery techniques are additional reasons for the growing numbers, says
Of the 6,275 women who had prophylactic mastectomy in the study, 81% of them
had been diagnosed with cancer in one breast. The rest had no personal
history of breast cancer, suggesting they had high risk factors for breast
cancer such strong family history and positive BRCA test results.
