According to the Understanding DCIS website,“For patients whose DCIS presents as dense soft tissue with no calcifications, ultrasound can be very helpful, and it is useful in DCIS cases that are palpable (can be felt).”
SonoCiné Automated Whole Breast Ultrasound (AWBUS) was invented by Dr. Kevin Kelly, a radiologist of 34 years who was passionate about improving ultrasound technology in an effort to find the tiniest cancers often missed by mammography (especially in dense breast tissue). Not only does it find the earliest of invasive cancers in extremely dense breast tissue, there is no squishing, no pain, no radiation, no IV, and no contrast dye.
In their article entitled US of Ductal Carcinoma In Situ in Radiology August 1, 2002, Woo Kyung Moon etal also found that ultrasound may be helpful in finding DCIS without calcifications. Additionally, they suggest that sometimes ultrasound guided biopsies can be a valuable tool.
Berg’s April 4, 2012 JAMA article concluded, “The addition of screening ultrasound or MRI to mammography in women at increased risk of breast cancer resulted in not only a higher cancer detection yield but also an increase in false-positive findings.”
