| 5/1/2012 | I had a negative mammogram, but on the screening ultrasound a TDLU was found. The Radiologist wants to do a vacuum biopsy. Another Radiologist recommends they usually leave TDLU's alone, and at most do a follow-up. What are your guidlines? Thank you. | ||

| 5/1/2012 | Terminal duct lobular units are a normal part of the anatomy of breast tissue. If a radiologist sees something that warrants biopsy due to it appearing abnormal and potentially of concern then a core biopsy is usually performed with ultrasound guidance. There must have been something seen or felt on the mammogram that resulted in the doctor then doing an ultrasound. | ||
