The recognition of the role of carcinogens in the production of malignancies led to a renewed interest in the ductal anatomy and physiology in the 20th century. Today, the combination of technological enhancement providing direct and indirect access to the luminal milieu and advances in cellular methodology that hold the promise of reliable diagnostic and predictive markers of breast cancer are driving investigators to pursue a ductal approach to breast cancer diagnosis and therapy that will be preemptive and accurate with less toxicity and breast disfigurement.
