Screening Mammography in Women 40–49 Years Old: Current Evidence

Abstract
OBJECTIVE. Breast cancer is an important health problem for women 40–49 years old, yet screening mammography for this age group remains controversial. This article reviews recent guidelines and supporting evidence on screening mammography in women of this age group. CONCLUSION. Evidence supports the benefit of annual screening mammography in women 40–49 years old. Models of different breast cancer screening strategies consistently show the greatest breast cancer mortality reduction and life-years gained with annual screening starting when women reach 40 years old.
