Breast Milk Liquid Biopsy for Early-Stage Breast Cancer Detection
Breast cancer has a worse prognosis when diagnosed during pregnancy or postpartum. Methods for early detection are needed, as evidenced every day in the multidisciplinary unit for treating pregnancy-associated breast cancer, which operates within the Breast Unit at the Vall d'Hebron University Hospital in Barcelona, Spain.
The team working in this field is led by Cristina Saura, PhD, who is also head of the Breast Cancer Group at the Vall d'Hebron Institute of Oncology (VHIO). The results of a study recently published in Cancer Discovery show, for the first time, that breast milk from breast cancer patients contains circulating tumor DNA (ctDNA) that can be detected by a liquid biopsy of the milk.
