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.
