"With good quality ultrasound and enough effort, it is possible in everyday practice to identify the DCIS process as it grows in the ductal system of the breast. It is quite possible to identify those minute wild and crazy calcifications of DCIS in the ducts itself and ultrasound-guided biopsy of DCIS is now an everyday procedure."
"Ductal carcinoma in situ (DCIS) is the non-obligate precursor of invasive breast carcinoma. In the context of "overdiagnosis" the low grade DCIS cases found on screening mammography are likely to cause the number of cases where the diagnosis of breast malignancy has been made but could conceivably not have been fatal to the patient. Remember that to try and guess the grade of DCIS on the mammogram images is not plausible or reproducible. Low grade DCIS is not a dangerous disease and there is actually some thought on following the disease with MRI after a histological diagnosis has been made."

"There are varied mammographic manifestations of ductal carcinoma in situ, with casting-type calcifications being the most common (present in 50-75% of cases 3). Other manifestations include a soft-tissue opacity either with or without associated calcifications."
