Evaluation of Mammographic Breast Density in Participants with Hormone Receptor-Negative Breast Cancer Enrolled on Study A011502

This phase III trial evaluates mammographic breast density in participants with hormone receptor-negative breast cancer enrolled on study A011502. High breast density has been shown to be a strong risk factor for developing breast cancer and decreasing breast density may decrease the risk for breast cancer. Participants treated with aspirin may show reduced breast density on a mammogram.
