Experts criticize new advice on mammograms

Some experts dismissed new guidelines by a government task force that urged women to wait for age 50 to get a regular mammogram and downplayed the importance of self-exams.

In a highly controversial move, an influential government-sponsored organization is recommending against routine annual mammograms for healthy women in their 40s.

After reevaluating scientific research on mammography's ability to reduce deaths from breast cancer, the U.S. Preventive Services Task Force says these women should consult a physician and make a decision reflecting their own preferences and values. The recommendation does not apply to women at high risk for the disease.

The group had previously suggested that women ages 40 to 49 be screened for breast cancer every one or two years.

``No one is saying that women should not be screened in their 40s,'' said Dr. Diana Petitti, vice chair of the task force, whose work is closely followed by doctors and insurance companies. ``We're saying there needs to be a discussion between women and their doctors.''

The task force's new guidelines also recommend against teaching women to do regular formal self-exams of their breasts, although several experts stressed that women should seek medical attention if they come across any unusual lumps spontaneously.

The new advice reflects a heightened appreciation of the potential harm associated with breast screening. No one disputes that mammograms help save lives, but they can be unreliable, identifying too many benign growths as cancerous, missing other tumors that are malignant and sometimes leading to medical interventions of questionable benefit, experts note.

The task force also is suggesting that women age 50 to 75 get the X-ray tests every two years instead of annually. There isn't sufficient evidence to recommend screening for women 75 and older, it says.

The new recommendations, which put the group at odds with two major cancer organizations, came under immediate fire from some breast cancer specialists. Critics say the change could undermine advances in detecting breast cancer early, treating it effectively and preventing deaths, which have dropped 30 percent since 1990.

`I don't think I will let this . . . change my recommendation,'' said Joyce Slingerland, professor of medicine at the University of Miami and director of the Braman Family Breast Cancer Institute at UM Sylvester Comprehensive Cancer Center.

``There is no new research science in this recommendation, and that's a problem for me,'' she said.

Slingerland wonders whether the new guidelines are based on economics instead of science. She cites these figures:

One-sixth of all breast cancer deaths arise in women diagnosed in their 40s.

Canadian and Swedish research studies show there was a 25 percent to 40 percent reduction in mortality rate in women in their 40s whose cancer is detected by mammography. ``That's a very significant gain.''

Underscoring deep disagreements among medical experts on the issue, the American Cancer Society and the National Cancer Institute said they had no plans to back down from their current positions. The society recommends annual mammograms for women starting at age 40; the cancer institute says every one to two years for that group.

Dr. Len Lichtenfeld, deputy medical officer for the American Cancer Society, noted that the data reviewed by the task force shows that starting screening at age 40 and annual screening does reduce mortality.

Fundamentally, said Petitti, the difference of opinion comes down to ``a judgment call . . . a weighing of the numbers'' quantifying potential benefits and harms.
