Q

Interventional breast procedures

Under sonographic guidance

A

needle guidance in an attempt to aspirate fluid, which would be diagnostic of a complex cyst

used to guide a fine-needle aspiration cytology (FNAC), abscess or seroma drainage and large-core needle biopsy (for tissue diagnosis)

A

arise from lining of breast ducts, retroareolar area most common
Bloody discharge from single duct

25
Q
