The recommendation statement by the USPSTF (1) sensibly concludes that the decision about mammography should be an individual one, reflecting the patient's values regarding specific benefits and harms. However, the USPSTF did little to enable women to understand these risks and benefits and did not help them to make sound choices about screening. For women in their 40s, the USPSTF considered a 55% chance of a false-positive result (2) to prevent 1 breast cancer death for every 1900 women screened to be unacceptable. Curiously, they reached the opposite conclusion for women in their 50s, in whom “only” a 46% chance of a false-positive result to prevent 1 breast cancer death for 1300 women screened is acceptable. The difference between 1 in 1300 and 1 in 1900 (0.053% vs. 0.077%) is so small that it is difficult to imagine a woman for whom it would matter, which makes this an odd policy distinction. This is a classic “close call” or “toss-up,” and either choice should be acceptable (3).
