She asks whether you agree that she should undergo screening. You know that trials of mammography screening support both a mortality reduction from breast cancer and the existence of overdetection and false-positive results, which may result in unnecessary investigations and overtreatment. You are unsure of the magnitude of these effects, which you know are crucial in helping your patient to make her decision. To help, you need to know how screening can be evaluated, how screening test results should be interpreted, and whether there are any valid, relevant, and up-to-date clinical practice guidelines or recommendations about screening for breast cancer.
