Important Changes to Mammography Recommendations

Women should start mammography screening at age 40, according to guidelines released earlier this year from the U.S. Preventive Services Task Force. The recommendation to start screening at age 40 is a change from prior years. Previously, the agency — an independent panel of national experts who issue period evidence-based medical guidance — recommended mammography screenings start at age 50 for most women at average risk for the disease.

The change is warranted to better protect younger women who develop breast cancer. Breast cancer rates have increased 2% per year among women in their 40s since 2015, according to data published in the Journal of the American Medical Association.

The new guidelines stipulate that women undergo mammography every other year until age 74. However, there are still discrepancies between organizations regarding mammography. The American College of Obstetricians and Gynecologists recommended mammography yearly from age 40 through 74. The American Cancer Society recommends screening yearly beginning at age 45 until menopause, followed by screening every other year.

Moreover, breast cancer screening guidelines vary according to a woman’s genetic risk profile, personal health history or family history. Breast density is also an important factor in deciding how often mammography is necessary. Women should speak with their personal health care providers to assess the most appropriate mammography schedule.
