When public health budgets are constrained, mammography screening should begin later and occur less frequently, a cost-effectiveness analysis for California’s Every Woman Counts (EWC) program concludes. As outlined in a paper published in Value in Health, the analysis focused on several policy questions, including the effect on EWC program costs and outcomes of starting screening at age 50 years instead of 40 and of screening every two years instead of every year. The study was conducted in response to recent government funding cutbacks, says a September 16, 2013 UC Davis news release, "UC Davis study applies timely cost-effectiveness analysis to state breast cancer screening program."
Some doctors advise women with dense breasts to look more at test results since dense breasts are more likely to hide cancer images than non-dense breasts. It's not about the size of the breasts. See, "Dense Breasts Pose a Dilemma in the Search for Breast Cancer." The issue is about being able to see more clear images of the cancer or detect it in dense breasts, not about whether dense breasts get cancer more often.

“This was not a clinical recommendation, but rather was intended to help a public health program use its resources to the greatest effectiveness,” explains lead author Joy Melnikow, director of the UC Davis Center for Healthcare Policy and Research, in the news release. EWC, administered through the California Department of Public Health Cancer Detection Section, is one of the largest of 68 Centers for Disease Control and Prevention-funded programs across the country. It reimburses providers at Medi-Cal rates (Medi-Cal is the California version of Medicaid) for screening and diagnostic services for breast and cervical cancers. It provides services to women who are not eligible for Medi-Cal, who otherwise lack coverage for breast and cervical cancer screening, and whose income is less than 200 percent of the federal poverty threshold.
The study, conducted by UC Davis and EWC researchers, was based on a sophisticated microsimulation model that projected outcomes based on existing program data
It found that starting mammography screening biennially at age 50 was strongly supported by the model results, given that program funding did not allow screening of the full population of eligible women beginning at age 40.
“Because breast cancer incidence goes up with age, using program funds to screen all eligible women over age 50 will have a greater impact on reducing breast cancer deaths,” says Melnikow in the news release. “The goal was to advise a public health program in a timeframe that could be helpful, given that cost-effectiveness analysis typically takes a long time to conduct — often too long to be of use in a quickly changing policy environment.”
The United States Preventive Services Task Force, a government medical task force, in 2009 recommended the same changes in breast cancer screening guidelines, suggesting that most women should not begin getting routine mammograms until age 50, and then only once every two years.
“The task force was asking a different question,” explains Melnikow in the news release. Melnikow became a member of the task force after the breast cancer screening recommendations vote. “In that case, cost-effectiveness and policy weren’t factors. Instead, the Task Force looked at recommendations for screening of women exclusively from a clinical point of view.”
Melnikow, a UC Davis professor of Family and Community medicine, points out that the EWC analysis has implications for other budget-constrained public programs around the country. What is being done to help consumers who go to health programs that have very tight or 'neighborhood' budgets or have to operate in face of continuing budget cuts?
Public health programs with limited resources
“This study is important for administrators who are doing their best to run public health programs with limited resources. We found that, although it can be challenging, it is by no means impossible to create carefully constructed cost-effectiveness analysis models quickly enough to be useful to programs and policy makers as they render important resource allocation decisions.”

The California Program on Access to Care and UC Berkeley School of Public Health in cooperation with the UC Office of the President provided the funding for the study
The Center for Health Policy Research conducts research on health-care access, delivery, costs, outcomes and related health policy to improve the organization, quality and effectiveness of the practice of medicine, especially primary care. The center is a resource for the university and health system on comparative effectiveness research.
Center faculty conduct original research, offer consulting services to agencies in both public and private sectors, and provide research training to fellows, graduate students and junior faculty. Established as an interdisciplinary unit, the center includes more than 80 health-care researchers who represent disciplines ranging from business management and psychiatry to preventive medicine, epidemiology and statistics.
