The purpose of this study is to evaluate the effect of two anti-inflammatory drugs, fish oil capsules and the COX-2 inhibitor celecoxib, on pregnancy associated breast cancer (PABC). Short-term intervention with anti-inflammatory medications will demonstrate a reduction in the inflammation and immune suppressive phenotype of PABC, and decreased metastatic potential in PABC. This unique window in breast cancer management serves as a valuable opportunity to obtain preliminary data on biomarkers and the alterations that occur when the system is troubled by a drug or other intervention which will be instrumental in designing future therapeutic or preventative strategies for larger clinical study.
