The controversy over breast cancer screening rages on, fueled by results from the Canadian National Breast Cancer Screening Study (CNBCSS) reported in the Sept. 3 issue of the Annals of Internal Medicine.
This study showed that mammography added to self-examination and physician examination of women in their 40s did not reduce the death rate from breast cancer compared with self-examination and physician examination alone.
In February, the U.S. Preventive Services Task Force (USPSTF) published guidelines giving B level recommendations for mammographic screening every one to two years for women in their 40s, meaning that clinicians should routinely provide mammography to eligible patients. But their review in the same issue Annals suggests that available evidence supporting this position is only “fair.”
An accompanying editorial, however, suggests that screening mammograms cause harm from increased rates of mastectomy and lumpectomy. In contrast, an observational study in the Aug. 24 issue of the British Medical Journal showed that while conservative procedures increased, radical mastectomy rates decreased with the advent of widespread screening.
