Earlier this month the US Preventive Services Task Force (USPSTF), an independent panel of respected experts in primary care and prevention, caused an uproar when they presented evidence that routine mammogram screening for breast cancer should not begin until the age of 50. The group based their recommendation on evidence showing that the “additional benefit gained by starting screening at age 40 years rather than at age 50 years is small, and that moderate harms from screening remain at any age”. Essentially, the number of women we need to screen in order to extend one woman’s life is far higher for the group between the ages of 40 to 49 than for the group aged 50 to 59. However, current US Health and Human Services secretary, Kathleen Sebelius, issued a statement yesterday stating that there will not be any changes to government policy on mammography: screening mammograms should continue to start at the age of 40.

Additional USPSTF recommendations include:
- Regular biennial screening mammography for women aged 50 to 74.
- No teaching of breast self-examination (BSE).
- There is not enough evidence to assess whether clinical breast examination (CBE) does more harm than good, beyond screening mammography in women 40 years or older.
- Current evidence is not enough to assess whether digital mammography or magnetic resonance imaging (MRI) would be better or worse than film mammography.
