Recommended Tests

NEW YORK – Most women don't need a mammogram in their 40s and should get one every two years starting at 50, a government task force said Monday. It's a major reversal that conflicts with the American Cancer Society's long-standing position.

Also, the task force said breast self-exams do no good and women shouldn't be taught to do them.

For most of the past two decades, the cancer society has been recommending annual mammograms beginning at 40.

But the government panel of doctors and scientists concluded that getting screened for breast cancer so early and so often leads to too many false alarms and unneeded biopsies without substantially improving women's odds of survival.

"The benefits are less and the harms are greater when screening starts in the 40s," said Dr. Diana Petitti, vice chair of the panel.

The new guidelines were issued by the U.S. Preventive Services Task Force, whose stance influences coverage of screening tests by Medicare and many insurance companies.

But Susan Pisano, a spokeswoman for America's Health Insurance Plans, an industry group, said insurance coverage isn't likely to change because of the new guidelines. No changes are planned in Medicare coverage either, said Dori Salcido, spokeswoman for the Health and Human Services department.

Experts expect the task force revisions to be hotly debated, and to cause confusion for women and their doctors.

"Our concern is that as a result of that confusion, women may elect not to get screened at all. And that, to me, would be a serious problem," said Dr. Len Lichtenfeld, the cancer society's deputy chief medical officer.

The guidelines are for the general population, not those at high risk of breast cancer because of family history or gene mutations that would justify having mammograms sooner or more often.

The new advice says:

_Most women in their 40s should not routinely get mammograms.

_Women 50 to 74 should get a mammogram every other year until they turn 75, after which the risks and benefits are unknown. (The task force's previous guidelines had no upper limit and called for exams every year or two.)

_The value of breast exams by doctors is unknown. And breast self-exams are of no value.

Medical groups such as the cancer society have been backing off promoting breast self-exams in recent years because of scant evidence of their effectiveness. Decades ago, the practice was so heavily promoted that organizations distributed cards that could be hung in the shower demonstrating the circular motion women should use to feel for lumps in their breasts.

The guidelines and research supporting them were released Monday and are being published in Tuesday's issue of the Annals of Internal Medicine.

The new advice was sharply challenged by the cancer society.

"This is one screening test I recommend unequivocally, and would recommend to any woman 40 and over," the society's chief medical officer, Dr. Otis Brawley, said in a statement.

The task force advice is based on its conclusion that screening 1,300 women in their 50s to save one life is worth it, but that screening 1,900 women in their 40s to save a life is not, Brawley wrote.

That stance "is essentially telling women that mammography at age 40 to 49 saves lives, just not enough of them," he said. The cancer society feels the benefits outweigh the harms for women in both groups.

International guidelines also call for screening to start at age 50; the World Health Organization recommends the test every two years, Britain says every three years.

Breast cancer is the most common cancer and the second leading cause of cancer deaths in American women. More than 192,000 new cases and 40,000 deaths from the disease are expected in the U.S. this year.

Mammograms can find cancer early, and two-thirds of women over 40 report having had the test in the previous two years. But how much they cut the risk of dying of the disease, and at what cost in terms of unneeded biopsies, expense and worry, have been debated.

In most women, tumors are slow-growing, and that likelihood increases with age. So there is little risk by extending the time between mammograms, some researchers say. Even for the minority of women with aggressive, fast-growing tumors, annual screening will make little difference in survival odds.

The new guidelines balance these risks and benefits, scientists say.

The probability of dying of breast cancer after age 40 is 3 percent, they calculate. Getting a mammogram every other year from ages 50 to 69 lowers that risk by about 16 percent.

"It's an average of five lives saved per thousand women screened," said Georgetown University researcher Dr. Jeanne Mandelblatt.

Starting at age 40 would prevent one additional death but also lead to 470 false alarms for every 1,000 women screened. Continuing mammograms through age 79 prevents three additional deaths but raises the number of women treated for breast cancers that would not threaten their lives.

"You save more lives because breast cancer is more common, but you diagnose tumors in women who were destined to die of something else. The overdiagnosis increases in older women," Mandelblatt said.

She led six teams around the world who used federal data on cancer and mammography to develop mathematical models of what would happen if women were screened at different ages and time intervals. Their conclusions helped shape the new guidelines.

Several medical groups say they are sticking to their guidelines that call for routine screening starting at 40.

"Screening isn't perfect. But it's the best thing we have. And it works," said Dr. Carol Lee, a spokeswoman for the American College of Radiology. She suggested that cutting health care costs may have played a role in the decision, but Petitti said the task force does not consider cost or insurance in its review.

The American College of Obstetricians and Gynecologists also has qualms. The organization's Dr. Hal Lawrence said there is still significant benefit to women in their 40s, adding: "We think that women deserve that benefit."

But Dr. Amy Abernethy of the Duke Comprehensive Cancer Center agreed with the task force's changes.

"Overall, I think it really took courage for them to do this," she said. "It does ask us as doctors to change what we do and how we communicate with patients. That's no small undertaking."

Abernethy, who is 41, said she got her first mammogram the day after her 40th birthday, even though she wasn't convinced it was needed. Now she doesn't plan to have another mammogram until she is 50.

Barbara Brenner, executive director of the San Francisco-based Breast Cancer Action, said the group was "thrilled" with the revisions. The advocacy group doesn't support screening before menopause, and will be changing its suggested interval from yearly to every two years, she said.

Mammograms, like all medical interventions, have risks and benefits, she said.

"Women are entitled to know what they are and to make their best decisions," she said. "These guidelines will help that conversation."

WASHINGTON – Women should continue getting regular mammograms starting at age 40, Health and Human Services Secretary Kathleen Sebelius said Wednesday, moving to douse confusion caused by a task-force recommendation two days earlier.

Sebelius issued her statement following a government panel's recommendation on Monday, that said most women don't need mammograms in their 40s and should get one every two years starting at 50.

That recommendation was a break with the American Cancer Society's long-standing position that women should get screening mammograms starting at age 40.

The task force does "not set federal policy and they don't determine what services are covered by the federal government," Sebelius said.

Medicare, which covers older Americans and some younger ones who are disabled, provides women on Medicare coverage for an annual mammogram at age 40 and older.

Sebelius noted that there has been debate about the age at which routine mammograms should begin, and how often they should be given.

"The task force has presented some new evidence for consideration but our policies remain unchanged," she said. "Indeed, I would be very surprised if any private insurance company changed its mammography coverage decisions as a result of this action."

"My message to women is simple. Mammograms have always been an important lifesaving 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," Sebelius said.

In the meantime, she added, it is clear that more research is needed into ways to help women prevent and fight breast cancer.

The recommendations from the task force have left women across the country confused about which advice to take. It also quickly led to charges from opponents of changing health care policy that it is an example of what could be expected from government-managed care.

In its report the panel of doctors and scientists concluded that such early and frequent screenings often lead to false alarms and unneeded biopsies, without substantially improving women's odds of survival.

But their recommendation was loudly criticized by breast cancer survivors who were diagnosed at a young age.
