Detection of subtle breast cancers with mammography : the importance of using the correct technology and technique

Abstract

Mammography is an excellent tool for the detection of breast cancer. Screening mammography has been repeatedly shown to reduce breast cancer mortality by up to 40%. It is also associated with earlier stage diagnoses that require less extensive treatment. However, screening mammography is not without its caveats. Ten to 30% of cancers can be missed if subtle findings are not detected. Breast cancer must be detected before it causes clinical symptoms, otherwise more treatment is required, and prognosis may be worse. [excerpt]
