The mammogram shows DCIS right breast. The ultrasound adds value; imaging suggests an IDC and pathological node in the axilla. The biopsy of the mass and FNAC of the node confirmed IDC and lymph node metastatic cells.
It is practical and easy to add FNAC of an axilla. The procedure is generally well tolerated. The yield of cells is in general proportional to the number of needle passes. I use three separate 21G needles and pass them in turn repeatedly through the node and inject the yield into cytolyte. Same process as used in thyroid FNAC.
