简要总结
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.

结局指标
主要结局
breast cancer risk factors and background parenchymal enhancement (BPE).
时间窗: 1 year
A comparison of the distribution of breast cancer risk factors in women with low and high levels of BPE. The relationship between risk factors and categories of BPE (minimal/mild/moderate/marked) will be determined using ordinal logistic regression.
次要结局
