ANN ARBOR, Mich. A new study questions the controversial U.S. Preventative Service Task Force recommendations for breast cancer screening, with data that shows starting at a younger age and screening more frequently will result in more lives saved.
The study analyzed the same data looked at by the task force, which issued its guidelines on mammography screening in November 2009. The study authors compared the task force's recommendations for screening every other year in women 50-74 to American Cancer Society guidelines of screening every year in women 40-84.
The study was conducted by R. Edward Hendrick, Ph.D., clinical professor of radiology at the University of Colorado School of Medicine, and Mark Helvie, M.D., director of breast imaging at the University of Michigan Comprehensive Cancer Center. It appears in the February issue of the American Journal of Roentgenology.
Hendrick and Helvie used six model scenarios of screening mammography created by the Cancer Intervention and Surveillance Modeling Network. This is the same modeling data the task force considered. The authors compared task force guidelines to American Cancer Society guidelines.
They found that if women begin yearly mammograms at age 40, it reduces breast cancer deaths by 40 percent. When screening begins at 50 and occurs every other year, it reduces breast cancer deaths 23 percent.
The difference between these two screening strategies comes down to 71 percent more lives saved with yearly screening beginning at 40.
"Task force guidelines have created confusion among women, leading some to forego mammography altogether. Mammography is one of the few screening tools that has been proven to save lives and our analysis shows that for maximum survival, annual screening beginning at 40 is best. This data gives women more information to make an informed choice about the screening schedule that's best for them," says Helvie, professor of
