National Mammography Database for Breast Cancer Screening and Diagnosis

This study, called the National Mammography Database (NMD), is collecting information from radiology practices that perform mammograms. It's not testing a new drug or treatment, but rather gathering data that these practices already collect to help them compare their results with national and regional averages. The goal is to see how well breast cancer is detected (Cancer Detection Rate) over one year. Anyone between 2 and 99 years old, regardless of gender, can be included in the data collection. There are no specific exclusion criteria. The current status of the study is unclear, but it aims to include data from 8,000,000 individuals.

    This outcome measure is measured using one year of follow-up after a mammogram is performed on a woman, and is aggregated by interpreting physician. Because the NMD is a registry and screening mammograms are annual exams for most patients, this measure is calculated each year using one year of follow-up.
