Target Audience

Health professionals.


Beginning January 1, 2018 with the enactment of Iowa law (SF250), all Iowa facilities that provide mammography service are required by law to notify patients of their breast density. This new regulation was mandated by the Iowa Department of Public Health. 

Breast density is determined through a woman’s mammogram and described as one of four categories. 40% of women age 40 and over have dense breasts. Cancer is 4-6 times more likely in women with extremely dense breasts than in women with fatty breasts. Though mammograms find some cancers not seen on other screening tests, in dense breasts, mammograms will miss more than 50% of the cancers present. Other screening tests, such as ultrasound or breast MRI, in addition to mammography substantially increase detection of early stage breast cancers in dense breasts.
