The American Cancer Society鈥檚 new 聽recommend that women start screening later and get fewer mammograms, but the change is unlikely to affect insurance coverage anytime soon.

The updated guidelines, which were published in the Journal of the American Medical Association this week, recommend that women who are at average risk for breast cancer start annual mammograms聽at age 45 and continue until age 54, then reduce screening frequency to once every two years. They should聽continue on that schedule as long as their life expectancy is at least 10 years. The ACS聽also no longer recommends that women receive manual clinical breast exams.
The previous guidelines, which had been in place since 2003, recommended annual mammograms and clinical breast exams starting at age 40 for women who were at average risk.
The update聽was two years in the making and reflects the society鈥檚 current thinking based on an analysis of existing science and changing technology, among other things, says Kirsten Sloan, the ACS Cancer Action Network senior director of policy. The society concluded that even though women in their early 40s can benefit from breast cancer screening, they are more likely than older women to get false positive results, which can lead to unnecessary — and sometimes harmful — additional testing and procedures.
The new guidelines on their own likely won鈥檛 change insurer and employer decisions regarding coverage of screening for breast cancer, experts agree.
Under the health law, health plans are required to cover preventive services that are recommended by the , a nonpartisan group of medical experts, without charging consumers anything out of pocket. The only exception is for plans that have grandfathered status under the law.
The task force’s breast cancer screening guidelines are slightly different than those from聽the American Cancer Society. The task force recommends mammograms to screen for breast cancer for women at average risk every two years starting at age 50 and continuing until age 74. The task force is revising the guidelines, but a聽 is similar to the existing one.
The new ACS guidelines now more closely align with the task force鈥檚 recommendation to start screening at age 50. However, both groups鈥 guidelines also say some women may choose to be screened earlier than the recommended age — but that聽the decision should be an individual one.
鈥淚n most cases, health plans are already covering mammograms for women age 40 to 50 when recommended by a doctor,鈥 said Clare Krusing, a spokeswoman聽for America鈥檚 Health Insurance Plans, an insurer trade group, in an email.
Health plans examine medical guidelines and evidence from a variety of sources when developing coverage rules.
鈥淭he recommendations will give plans a different framework for evaluating those coverage decisions moving forward, particularly if more and more doctors, providers [and] researchers release recommendations that align with those coming out from the ACS,鈥 says Krusing.
