Benign and malignant type microcalcifications localized within the major ducts with main emphasis on fragmented casting type calcifications.
This is the second of three lectures dealing with benign and malignant type microcalcifications localized within the major ducts. There are no differential diagnostic problems in separating the secretory disease type/benign type calcifications localized within the duct system from the malignant type calcifications, but calcifications occurring in traumatic fat necrosis may cause considerable differential diagnostic problems.
The lecture presents efficient approach to analysis of calcifications detected on the mammograms, such as their predominance among younger women. The process of neoductgenesis accounts for the highly malignant nature of this subtype of breast cancer, including its resistance to chemotherapy and radiation therapy.
