Preventing breast cancer in the years after childbirth

Targeted Prevention of Postpartum-Related Breast Cancer (PRBC)

NIH-funded research Mayo Clinic Jacksonville · NIH-11298953

This project tries to prevent breast cancer that appears within five years after giving birth by studying whether common anti-inflammatory drugs like aspirin can lower that risk for women who recently had a baby or have benign breast disease.

What this research studies

This project looks at how the breast heals after weaning and whether that healing process causes inflammation that raises cancer risk. Researchers will examine breast tissue samples and biopsies, review medical records for NSAID (like aspirin) use, and use lab models to link inflammation to cancer development. The team will combine lab work with studies of women’s medical data to see if blocking inflammation could stop postpartum-related breast cancers. Findings could point to simple prevention steps or identify women who might benefit most.

Who could benefit from this research

Good fit: Ideal candidates are women within about five years after giving birth, especially those with benign breast disease or a family history of breast cancer.

Not a fit: People who have never been pregnant, whose cancers are unrelated to postpartum changes, or men are unlikely to benefit directly from this research.

Why it matters

Potential benefit: If successful, this work could point to a low-cost way (for example, aspirin or other NSAIDs) to lower the chance of developing breast cancer after childbirth.

How similar studies have performed: Animal studies and observational research have suggested NSAIDs can reduce postpartum-related breast cancer risk, but randomized prevention trials in postpartum women are still limited.
