Mammography screening has been shown to reduce breast cancer mortality and remains the primary screening method. However, the harms of false-positive results and over-diagnosis have recently been emphasized, and screening guidelines have been revised. Breast ultrasonography screening has the advantage of detecting mammographically occult breast cancers in dense breasts; however, false-positive results and rising medical costs due to increased biopsy recommendations create a problem. Till date, recommendations for breast ultrasonography screenings have not been established. Magnetic resonance imaging is recommended for women at high risk and has excellent sensitivity, but it is expensive and inferior in accessibility. This article reviews the benefits, harms, and guidelines of methods commonly used in breast cancer screening. This review also provides breast cancer screening methods according to individual breast cancer risk.
