Assuming your patient does not have a breast symptom or abnormal physical exam, first screen your patients for any of the following red-flag risk factors.

Strongly consider additional screening with breast MR which has been shown to be the most sensitive method to detect additional cancers missed at mammography.
You can reassure her regarding the minor incremental increase in risk associated with her breast density (Relative Risk = 1.2 for women with heterogeneously dense breasts and Relative Risk = 2 for women with extremely dense breasts, compared to women with average breast density), and encourage her to continue annual mammographic screening. Breast density limits the sensitivity of mammography in the detection of breast cancer.
