MRI Parenchymal Enhancement: A New Marker of Breast Cancer Risk

Epidemiology of MRI Parenchymal Enhancement: A New Marker of Breast Cancer Risk

The purpose of this study is to learn about how a woman's health history influences what a normal breast looks like on an MRI. The investigators also want to learn about how the amount of different natural hormones a woman has affects how the breast looks on an MRI. The investigator's hope is that this will help to find women at a high-risk of breast cancer.
