Summary

This trial tests whether low-dose aspirin can reduce inflammation in postpartum patients with benign breast disease, which may prevent breast cancer.

Who is the study for?

This trial is for postpartum women aged 18-45 with benign breast disease who've had a live birth within the last 10 years. They must have hemoglobin levels >=9.0 g/dL, platelet count >=100,000/mm^3, serum creatinine =<2.0 mg/dl, and not be pregnant or planning pregnancy soon. Participants should not be on aspirin/NSAIDs or have any contraindications to aspirin use.

What is being tested?

The study tests if low-dose aspirin can change inflammation markers in blood/tissue which might prevent breast cancer after childbirth. It involves biospecimen collection, questionnaires, and ultrasound-guided biopsies to monitor effects.

What are the potential side effects?

Potential side effects of low-dose aspirin may include increased risk of bleeding, stomach issues like ulcers or heartburn, allergic reactions in those sensitive to NSAIDs, and possibly bruising more easily.

Experimental Treatment

Group I: Prevention (low-dose aspirin)Experimental Treatment4 Interventions

Patients undergo standard of care breast biopsy for assessment of abnormalities seen on imaging, as well as collection of blood during screening. If cancer is found, patient is taken off study and treatment options are discussed with treating physician. Patients without a cancer finding on biopsy then receive low-dose aspirin by mouth daily for 42-65 days and undergo collection of blood on study. Patients may undergo ultrasound guided breast biopsy as clinically indicated.
