Screening Mammography for Average-Risk Women: The Controversy and NCCN's Position.

ABSTRACT

Breast cancer remains the most common nonskin cancer among women and a leading cause of morbidity and mortality. Early detection through screening and advances in treatment have contributed to a 39% mortality reduction in the United States since 1990. The NCCN Guidelines for Breast Cancer Screening and Diagnosis recommend annual mammographic screening for average-risk women beginning at age 40 years. Mammographic screening and subsequent treatment reduces breast cancer mortality based on a wide range of studies. This article highlights NCCN's position on screening mammography and the screening controversy.
