Getting a Mammogram: Why the Conflicting Recommendations?

The controversy over when to start screening mammograms and how often to get them in average risk women has been around since the early 1990s. The American College of Radiology (ACR), United States Preventive Services Task Force (USPSTF) and American Cancer Society (ACS) all agree that screening every year starting at 40 will save the most lives. And yet, all three organizations have different recommendations for patients about mammograms.

The ACR, along with the National Comprehensive Cancer Network (NCCN), American Congress of Obstetricians and Gynecologists, and American College of Surgeons recommend screening every year starting at age 40. The ACS recommends considering a mammogram between ages 40 to 44 then definitely getting one every year between ages 45 to 54, followed by continued screening every one to two years. The USPSTF draft for 2015 recommends starting at age 50 and getting a mammogram every other year. How can all these prestigious organizations, which are full of smart people, look at the same data and come to different conclusions?

The issue boils down to one important question: Should patients decide or should organizations decide for them?

While all agree that starting at age 40 and getting a mammogram every year saves the most lives, the reason why they disagree about when to start has to do with the relative value that each group places on the potential risks and costs associated with screening mammography. These include the money and time spent on the exam, the anxiety it may cause and the possible additional tests that the mammogram may generate when cancer is not present. Different patients often value each of the risks and benefits from a mammogram differently. Some are more anxious than others. Some have greater concerns about the expense of the exams. And some have a more pressing need to know the results.

The UPSTF and the ACS have tried to weigh the life-saving benefit of mammograms against the risks and choose what is best for all patients. Unfortunately, the USPSTF recommendations are tied to insurance coverage through the Affordable Care Act. For women between the ages of 40 to 49 years old the Task Force has assigned mammography a grade C. A grade C does not require insurance coverage. While the words of the USPTSF suggest the freedom of choice, their actions may require patients to pay the full cost of a mammogram from their own pocket. Those with limited incomes may have no choice at all.

The ACR, NCCN and others recognize that women at average risk for breast cancer have different values and support continued insurance coverage for patients to get a mammogram and exercise their right to choose for themselves. The opportunity should be offered every year beginning at age 40 because – as the ACR, ACS and USPSTF agree – that is the schedule that saves the most lives.

More Information: Two organizations in their own words

The ACS says

“Screening mammography in women aged 40 to 69 years is associated with a reduction in breast cancer deaths across a range of study designs, and inferential evidence supports breast cancer screening for women 70 years and older who are in good health.”
[Oeffinger KC et al. Breast Cancer Screening for Women at Average Risk 2015 Guideline Update From the American Cancer Society JAMA. 2015;314(15):1599-1614]

The USPSTF says

“The USPSTF found adequate evidence that mammography screening reduces breast cancer mortality in women ages 40 to 74 years.”

    What is the thought about women who
    were exposed to aerial spraying and
    truck spraying of ddt for the first 30 years of my life! Two of my female
    cousins raised with me in Florida were
    diagnosed with breast cancer one of
    which has died. Both tested negative
    for the BRCA genes. Neither of my
    sisters has been diagnosed with
    breast cancer. I should mention
    that I’m an Ashkenazi Jew and am
    65 years old. I have had many
    mammograms at Virginia Mason with
    negative results! I don’t know what
    to this year. You have my permission to look at my records if you want to! I’m
    the only Lemlich at Virginia Mason. I really need some advice if you have time to give it!!!

  2. Hi Sandra, please contact your doctor directly. That would be the best place to start in addressing your concerns. Thank you.
