Glandular tissue is made up of ducts and the milk glands (called lobules). The ACR recognizes that breast density has an impact on mammographic screening. Apply today. It is well known that greater breast density results in lower sensitivity for mammography. Breast density assessment is an important component of the screening mammography report and conveys information to referring clinicians about mammographic sensitivity and the relative risk for developing breast cancer. Exploratory analyses were performed of the iCDR in both study arms and stratified by breast density, and odds ratios and 95% CIs were determined.
