That most screening test results will be normal or negative is commonplace, but the reality that abnormal results are frequently false-positive is not always well appreciated, nor is it fully conveyed to patients. How does a patient feel after a false-positive test result? Tosteson and colleagues1 concluded from their longitudinal study that “false-positive mammograms are associated with a measurable, small, and transient effect on personal anxiety.” However, a closer look at all the outcomes assessed in this well-done study reveal some adverse consequences that, although not serious, may nonetheless be meaningful.
