About this trial
This phase II trial tests whether low-dose aspirin can affect markers of inflammation in postpartum (after childbirth) women planning to have a breast biopsy. Chronic inflammation may increase the risk of postpartum related breast cancer. Low-dose aspirin is a non-steroidal anti-inflammatory drug. Giving low-dose aspirin may affect markers of inflammation in blood and tissue and may prevent postpartum related breast cancer.

Trial outcomes
Primary outcomes
Change in pregnancy-related breast cancer (PRBC) score
Assessed using pre- versus post-treatment PRBC scores. Patients who are eligible, consented, received at least 70% of the study treatment, and provided both a pre- and post-intervention tissue specimen will be evaluated for this outcome.
Secondary outcomes
Change in postpartum involution (PPI) signature score
Assessed using pre- and post-intervention PPI signature scores for each person.
Other outcomes
Change in percent of epithelial cells positive for COX-2, estrogen receptor (ER)/Ki67, gammaH2AX, and p16 in "normal" and in benign breast disease (BBD) lobules
The change in percent of positive epithelial pre- and post-intervention will be assessed for each person.
Change in serum C-reactive protein (CRP), estrogens, insulin/insulin-like growth factors (IGFs), and adipokines
Serum values will be measured pre- and post-intervention for each person.
Changes in tissue and urine prostaglandins (PGs) and PGE2
PGs will be measured pre- and post-intervention for each person.
