Mammography screening should be offered annually to women beginning at age 40 years, according to a new recommendation by The American College of Obstetricians and Gynecologists (The College).1 This change was brought about by the high incidence of breast cancer in the United States. Early detection of breast cancer has the potential to reduce the number of breast cancer–related deaths. The College previously recommended that women aged 40 years receive mammograms every 1 to 2 years and women aged 50 years have mammograms annually.
