Mammography use among women aged 18-39 years in the United States.

Among U.S. women aged 18-39 years with no personal cancer history, one in seven reported having received a mammogram. Women with no family history of breast cancer were as likely as those with a family history to initiate breast cancer screening with mammography before age 40. Our findings provide evidence that supports further research to examine factors that prompt young women to receive screening mammograms.
