Since it is customary for nurse practitioners (NPs) to encourage each other in the workplace,
... Read MoreIn the past month, two sets of screening guidelines for women have been issued—one about Pap tests and the other about mammograms. The Pap test guidelines seemed to slip below the radar, but the mammography guidelines have created quite an uproar.
Starting with the less controversial recommendation…the cervical cancer screening guidelines issued by ACOG have increased both the age at which screening begins and the intervals between tests. This past summer, two NPWH board members and I attended a meeting at the NIH to review data about cervical cancer screening for adolescents. Starting at age 21 actually makes sense. Cervical cancer before age 21 is extremely rare. Abnormal Pap test results in this age group are primarily the result of a transient HPV infection. Furthermore, when abnormal results are found, clinicians are duty bound to do something about it. When that something is a LEEP or other procedure, it can compromise a woman’s future ability to achieve and maintain a healthy pregnancy. Cervical cancer is a slow-growing disease. The downside of delaying screening until age 21 and increasing the inter-screening interval is small.
Mammography and self-breast exam (SBE) guidelines from the US Preventive Services Task Force are another story. Teaching SBE enables women to know their own body, and it conveys the message that body awareness is good and healthy. Also, the recommendation against teaching SBE was based on a large study in Shanghai and one in Russia.
The most controversial recommendation was the one that women, unless they are “high risk,” should defer getting a baseline mammogram until age 50. The rationale is that the number of false-positives in women in their 40s has caused unnecessary anxiety, follow-up procedures, and extra costs. I’d be willing to bet that, if put to a vote, most women would be happy to deal with a false-positive test result if it meant that another woman’s life would be saved by earlier detection of a potentially lethal breast cancer.
Data underlying the new breast cancer screening recommendation are quite different from those underlying the cervical cancer screening guideline changes. The diseases are very different. Breast cancer may take 8-10 years, on average, to become detectable, but when it is detected, it needs to be treated—not in 10 years, but now. According to the National Cancer Institute, 1 of every 69 women aged 40-49 years will get breast cancer. Also, only 80% of breast cancers are related to a family history and only 10% are due to BRCA1/2. If only “at-risk” women in their 40s are screened, some women with potentially treatable breast cancer will not be diagnosed until after their first baseline mammogram at age 50, at which point the disease may have progressed too far to ensure a good outcome. The American Cancer Society is strongly opposed to the USPSTF recommendations. Even the DHHS says that women should continue doing what they’ve always done.
So, I suggest that we NPs keep doing what we’ve been doing for our patients in terms of breast cancer screening, but that we adjust our practice for cervical cancer screening. I direct you to the NPWH website (http://www.npwh.org/) so that you can keep up with the latest screening recommendations and the reactions of major health organizations to them.
Best wishes for a healthy and happy holiday season!
