RSNA members who peppered the briefing applauded as the University of Cincinnati's Dr. Mary Mahoney, vice-chair of the RSNA Public Information Committee, introduced the panel members, saying "These truly are the experts in mammography. It's unquestionable: Mammography saves lives."
The panel members were expressing their dissatisfaction with the newly revised guidelines from the USPSTF that recommend against routine mammography screening for average-risk women in their 40s. USPSTF also recommends women ages 50 to 74 have mammograms every two years instead of every year.

"The net effect of the new guidelines is that screening would begin too late and its effects would be too little. We would save money, but lose lives," said Dr. Stephen Feig, professor of radiology at the University of California, Irvine and president-elect of the American Society of Breast Imaging.
The breast-screening panel said the guidelines would represent a major setback, wiping out decades of progress.
"Deaths from breast cancer have dropped by 30% since 1990 when mammography screening beginning at age 40 became more widespread," said Dr. Daniel Kopans, professor of radiology at Harvard Medical School.
Kopans said the task force relied on studies with methodology flaws that underestimated the benefits of mammography.
Feig cited several U.S. and international studies that showed the benefits of annual screening beginning at age 40. Among them was a Swedish study showing that annual mammograms reduce breast cancer mortality by 44% among women who are actually screened.
Radiologists said that concerns about the harms of false positives led the Task Force not to recommend screening for younger women.
"You're going to have some false positives, if you detect cancer early," when it is most curable, Feig said.

Feig also discounted concerns about radiation exposure. "The risk is negligible compared with the benefits of screening," he said.
The breast-screening panel said it supports American Cancer Society (ACS) guidelines, which continue to recommend annual routine mammography screening for all healthy women ages 40 and older.
"Current American Cancer Society guidelines have been shown to save lives," Kopans said. "The Task Force, by its own admission, said women will lose their lives. That doesn't seem to be much of a choice."
Dr. W. Phil Evans, of the University of Texas Southwestern Medical Center, and president of the Society of Breast Imaging, said that the ACS, the American College of Obstetricians and Gynecologists, the Mayo Clinic, the American Society of Breast Disease, and the American College of Radiology are all opposed to the USPSTF guidelines. Only two organizations -- the National Breast Cancer Coalition and the Dr. Susan Love Research Fund -- are in favor of them.
Kopans said he thinks the government panel had "good intentions." Evans agreed, pointing out that 12 of its 16 members had multiple graduate degrees.
However, there were no radiologists on the panel, he said.
Kopans said he tried to e-mail the USPSTF data from several studies showing that mammograms save lives, but as far as he knows, his e-mail was ignored.

Asked if he thought radiologists were biased, Kopans said, "I would argue if there is no conflict of interest, you're not an expert. But we have true intentions and are saying to look at the data."
A big worry, the panel agreed, is that the USPSTF's recommendations will be used in any possible health plan being considered in Congress. That, in turn, would lead insurance companies to stop covering annual breast screening beginning at age 40, it said.
In fact, mammograms are cost-effective, Feig said. He presented data showing that a quality year of life saved with mammography costs $17,000. In contrast, a quality year of life saved with dialysis costs $55,000.
At a House Energy and Commerce Subcommittee on Health hearing in Washington, DC, today, Dr. Diana Petitti, vice chair of the USPSTS, said that while no radiologists were on the Task Force, they were "consulted and reviewed the recommendations and provided input."
Petitti told the hearing that their message could have been better communicated, and that it wasn't saying women younger than 50 shouldn't have mammograms, just that for them, the risks of mammography may outweigh the benefits.
Told about the hearing, Kopans said that the average primary care doctor only sees about two breast cancer patients a year.
"They don't know much about breast screening. Women have to be smarter than their doctors and save themselves," he said.
A second congressional hearing on the issue is planned.
