New Breast Cancer Guidelines Spark Controversy

New recommendations for breast cancer screening by the U.S. Preventive Services Task Force have raised considerable controversy.

Last week, two separate groups released new recommendations regarding cancer screening for women. On Nov. 16 the U.S. Preventive Services Task Force reversed decades of previous recommendations regarding mammograms to detect breast cancer. Then, on Nov. 20, the American College of Obstetricians and Gynecologists released their new guidelines for Pap smears, a procedure for detecting cervical cancer. Both sets of recommendations raise the age when women should begin getting tests, and increase the time between regular testing.

The task force, a non-partisan 16-member group convened by the U.S. Department of Health and Human Services, advised women to receive their first mammogram at age 50, instead of the previous recommendation of 40. It goes on to increase the time between mammograms to every two years until age 74, instead of having an annual exam. The task force sees no value in continuing mammograms after 75, and it also recommends against self-exams, saying there is no evidence that self-exams are useful in finding or preventing breast cancer. Women in their 40s have a lower risk of developing breast cancer, the task force said, so screening at that age is less beneficial. "The decision to start regular, biennial screening mammography before the age of 50 years should be an individual one," the task force wrote, and should take the "patient's values" into account.

A federal committee of medical experts made similar recommendations for mammograms in 1997, The Washington Post reports. Twelve years ago, the suggestion sparked congressional hearings, resulting in the U.S. Senate unanimously challenging the findings.

"What they are saying is that a careful review of the scientific evidence shows that in younger women of average risk the risks outweigh the benefits of routine screening. Understandably, this is a shocking statement to hear, as it completely contradicts the 'women should get an annual mammogram starting at age 40' recommendation that we've been hearing for the past decade. What many people don't know is that this recommendation to extend screening to women under 50 was fraught with controversy. The decision was not based on evidence; it was based on political will," wrote Dr. Virginia Ernster in the American Journal of Public Health at the time.

Dr. Susan M. Love, a pioneer in the field of women's health, said the task force recommendations are exactly what is needed in health-care reform: recommendations based on solid science and not popularity. Love has long been a critic of excessive mammography, which can expose women to unneeded radiation early in life, and often lead to false positives and biopsies that do not turn out to be cancer.

The Center for Medical Consumers writes on its Web site that the findings are based on solid science. "If you want to make an informed decision about mammography, go directly to the scientific evidence instead of your doctor," the organization says, providing numerous links to back up the new guidelines.

Mississipi ranks No. 47 in the nation for incidents of cancer, according to a new report by the United Health Foundation. Cancer rates have fallen in the last few years, leading some to question the new recommendations.

"I strongly disagree with the notion that preventing the psychological harms and inconvenience caused by false-positive screening results, as implied in the recommendations, outweigh the importance of saving one woman's life. We should not be in the business of rationing care," Eleanor Hinton Hoytt, president and CEO of the non-profit Black Women's Health Imperative, which works to alleviate health disparities for black women through education and advocacy, said in a statement. "Historically, researchers have not studied black women. Black women have not been at the forefront of the breast cancer movement, and our unique health experiences and outcomes have not been factored into policy and advocacy decisions. These recommendations completely ignore the impact of well-known breast cancer disparities affecting us."

The American Cancer Society responded immediately to the task force mammogram recommendations.

"The American Cancer Society continues to recommend annual screening using mammography and clinical breast examination for all women beginning at age 40, said Dr. Otis W. Brawley, chief medical officer of the ACA in a statement. "Our experts make this recommendation having reviewed virtually all the same data reviewed by the (the task force), but also additional data that the (task force) did not consider. When recommendations are based on judgments about the balance of risks and benefits, reasonable experts can look at the same data and reach different conclusions."

Brawley essentially accused the task force of giving a death sentence to some women with their recommendations. "The USPSTF says that screening 1,339 women in their 50s to save one life makes screening worthwhile in that age group," he stated. "Yet USPSTF also says screening 1,904 women ages 40 to 49 in order to save one life is not worthwhile. ... "With its new recommendations, the USPSTF is essentially telling women that mammography at age 40 to 49 saves lives; just not enough of them."

Still, HHS Secretary Kathleen Sebelius says the government's official policy has not changed, and she does not expect insurance companies to their policies at this point.

"What is clear is that there is a great need for more evidence, more research and more scientific innovation to help women prevent, detect, and fight breast cancer, the second leading cause of cancer deaths among women," Sebelius said in a statement.

"My message to women is simple. Mammograms have always been an important life-saving tool in the fight against breast cancer and they still are today. Keep doing what you have been doing for years—talk to your doctor about your individual history, ask questions, and make the decision that is right for you."

As for the American College of Obstetricians and Gynecologists, it now recommends that women delay their first Pap smear to screen for cervical until they are 21, and receive regular testing every two years until age 29. They also advise low-risk healthy women over 30 to limit testing to every three years. The college's previous recommendation was to begin testing for cervical cancer three years after becoming sexually active, or at age 21, with annual screenings thereafter.

The college's new recommendations for cervical cancer screenings have caused less of an uproar, perhaps because the organization was responsible for the previous guidelines and has a history of updating its findings on a regular basis. Dr. Cheryl B. Iglesia, chairwoman of the panel that developed guidelines, told The New York Times that the latest recommendations had been in the works for several years, "long before the Obama health plan came into existence."

Iglesia went on to say that there is more potential for harm in overusing Pap tests. Young women are especially prone to develop abnormalities in the cervix that appear to be precancerous, but that will go away if left alone, she told The New York Times. But when Pap tests find the growths, doctors often remove them, with procedures that can injure the cervix and lead to problems later when a woman becomes pregnant, including premature birth and an increased risk of needing a Caesarean.

The announcements triggered political accusations from both sides of the aisle. Sen. Tom Coburn, R-Okla., who is also a physician, told The New York Times he would continue offering Pap smears to sexually active women, insinuating that the Democratic proposals for health-care reform would likely lead to adopting the new recommendations regardless of patient differences. Democratic Rep. Rosa DeLauro of Connecticut, meanwhile, accused Republicans of "using the new recommendations as a distraction."
