Making sense of new breast cancer screening guidelines, from Harvard Women's Health Watch
Updated breast cancer screening guidelines from the United States Preventive Services Task Force have sparked a debate about how best to use the special breast x-rays known as mammograms. The debate is likely to continue as more information comes in, technologies change, and practices are reviewed. For now, there are several things women can do to help determine what's best for them, reports the February 2010 issue of Harvard Women's Health Watch.
An expert panel re-examined the evidence on the effectiveness of breast cancer screening in women ages 40 and older who are at average risk for developing breast cancer. It concluded that mammograms, clinical breast exams, and breast self-exams should be scaled back. The most controversial recommendations were to delay starting routine mammograms from age 40 to age 50, and to check women in their 50s and 60s only once every two years, rather than every year.
Breast cancer and imaging experts have weighed in for and against the revised guidelines. Advocates welcome a more cost-effective approach to screening and emphasize the potential to reduce unnecessary biopsies and psychological stress. Opponents point to a falling breast cancer death rate that's due, in part, to women having annual mammograms. Others worry that increasing the interval between mammograms will cause some women to skip the test altogether.
