Some women cutting off cancer before it strikes

More healthy women opting for double mastectomies, though doctors say procedure is not for everyone

  • Things to know about screenings • There has been lots of controversy in recent years over the usefulness of annual mammograms for some women. The U.S Preventive Services Task Force says they aren’t needed until women reach 50 and that it’s OK for women not at high risk to have scans every other year. • But the American Cancer Society and many breast cancer centers continue to recommend annual mammograms starting at 40. The cancer society also recommends clinical breast exams by physicians annually, beginning at the same age as mammograms. • For those at high risk for breast cancer because of family history, annual screening should begin before age 40. • Breast cancer risk goes up with age. The often-repeated statistic that “1 in 8” women will get breast cancer is calculated over a lifetime to age 95. The National Cancer Institute has created a Breast Cancer Risk Assessment Tool.

At age 23, Lindsay Avner took charge of her genetic fate: She elected to have her healthy breasts removed before cancer could strike first. Six years later, the Chicago woman has zero regret, she said.

“I feel so fortunate to have had this opportunity that generations of women before me never had,” said Avner, who was 11 when her mother was diagnosed with breast cancer, the same disease that claimed the lives of her grandmother, great-grandmother and others in her family tree.

So when Avner tested positive for the gene mutation that increased her odds of becoming another victim, she opted for a double mastectomy. She was heralded as a “pioneer” by her physician at Memorial Sloan Kettering Cancer Center in New York.

Now, the decision to remove disease-free breasts is not nearly as controversial as it was back in 2006, when Avner had surgery. Many more women, including a recent Miss America contestant, have disclosed that they have made the same decision either because of hereditary factors or finding early stage cancer in one breast.

Still, some clinicians think the pendulum has swung too far for women who do not have the gene mutation, with more of them opting for double mastectomies as the first line of defense. The increase is attributed to a number of factors, including a barrage of health campaigns that cause some women to overestimate risks and the misconception that removing both breasts guarantees you will never have breast cancer, experts said.

The rate of prophylactic – or preventive – mastectomy among U.S. women with cancer in one breast rose by about 150 percent from the late 1990s to the mid-2000s, according to multiple research studies.

Dr. Todd Tuttle, chief of surgical oncology at the University of Minnesota, said he found in a study that 1.8 percent of women with cancer in one breast had a double mastectomy in 1998. The percentage rose to 4.5 percent in 2003.

About 1 in 8 U.S. women – or roughly 12 percent – will develop breast cancer in their lifetimes. That’s compared with 60 percent of women, such as Avner, who have inherited a harmful mutation in human genes that are known as tumor suppressors, according to the National Cancer Institute. Even without the genetic mutation, the breast cancer risk roughly doubles if there’s a strong family history, such as a mother, sister or daughter who has been diagnosed with the disease.

Never again

Most preventive double mastectomies in the United States are being chosen by young women in the earliest stages of the disease, clinicians said. But this group has an excellent prognosis without a double mastectomy, said Dr. Seema Khan, professor of surgery at the Feinberg School of Medicine at Northwestern University, who, like the other physicians interviewed, wants patients to have a better understanding of the risks and benefits of the procedure.

“Women with unilateral breast cancer … are coming into doctors’ offices with disturbing frequency with the declared intent of undergoing a ‘double mastectomy’ so that they will ‘never have to do this again,’ ” Khan wrote in 2011.

“This has us really scratching our heads,” she said in a interview. “There’s no medical evidence that a bilateral mastectomy for this group increases length of life or survival rates … or has any better outcomes than breast-conserving treatment and radiation,” which is the standard.

Typically, a double mastectomy is a four-hour surgery, compared with versus one hour for a breast-conserving procedure, also called lumpectomy. It carries a significantly higher risk of surgical complications, such as infection and bleeding, than a single mastectomy, Khan said.

Many who undergo mastectomy in the unaffected breast do so because they mistakenly think they’ll never have to worry about a recurrence. “That’s a fallacy, because a malignancy can return on the skin of the (chest) wall,” Khan said.

Several factors are driving the phenomena, including pervasive health campaigns that are helpful but also can provoke unnecessary anxiety.

The risk that a woman with breast cancer will develop cancer in the second breast is about 5 percent over a 10-year period, but according to one study, women estimate their chances at about 30 percent.

“Breast cancer awareness is a good thing, but women just get pounded with these messages all the time,” Tuttle said. “When the NFL has ‘pink days,’ you know it’s over the top.”

Less aggressive options

For women without the gene mutation who are considering removing one or both cancer-free breasts, Dr. Dennis Citrin, medical oncologist for Cancer Treatment Centers of America, advised surveillance and preventive drug therapy.

A double mastectomy would be an aggressive approach and unnecessary, according to clinicians and published medical reports.

But it’s women with cancer in one breast and considering double mastectomy who give clinicians the most concern.

Some oft-cited reasons for the uptick range from improved reconstruction techniques to less stigma surrounding the surgery, as women announce publicly what was once only whispered.

Celebrities Christina Applegate and Sharon Osbourne have all talked openly about their operations. Miss Washington, D.C., Allyn Rose, 24, disclosed in January that she would have both breasts removed after the Miss America pageant. She had not had any genetic testing but didn’t want to take any chances with the disease that killed her mother, who was diagnosed at 27.

“I don’t have the luxury … of waiting around,” she told reporters.
