Brief Summary

RATIONALE: Aspirin may be effective in reducing breast density in healthy postmenopausal women with a moderate or high level of breast density. PURPOSE: This randomized clinical trial is studying the effect of aspirin on mammogram density compared with a placebo in healthy postmenopausal women with a moderate or high level of breast density.

Outcome Measures

Primary Outcomes (1)

  • Comparison of the effect of acetylsalicylic acid (aspirin) vs placebo on mammographic density

    Baseline and end-of-study (6 month timepoint)

Secondary Outcomes (4)

  • Differential response in mammogram density to aspirin treatments in individual homozygous wild-type, heterozygous, and homozygous variant for several UGT gene polymorphisms

    Baseline and end-of-study (6 month timepoint)

  • Adverse events

    Collected over the course of tehestudy

  • Putative biomarkers of breast and ovarian cancer

    Baseline and end-of-study (6 month timepoint)

  • Comparison of the effect of aspiring vs placebo on serum levels of estradiol, estrone and sex hormone binding globulin

    Baseline and 6 month timepoints
