Kathleen Arcaro, a former Family Research Scholar, supported by a $718,000 grant from the Department of Defense's Breast Cancer Research Program, is hoping to develop a new screening for BRCA-Positive Breastfeeding Women. The new, noninvasive test uses women’s breast milk to detect breast cancer in its earliest stages. New mothers, and to a greater extent those with a BRCA mutation, face an increased risk of pregnancy-associated breast cancer (PABC), which is often aggressive, for about a decade postpartum.
