Metastases from breast cancer can be frequent finding in routine onco-radiological practice.
With the universal use and acceptance of screening mammography, the isolated clinical presentation from metastases from breast carcinoma have become rare in clinical practice. Historically, presentation from metatsases was much more common than it is now.
More commonly, the primary breast malignancy is known at the time the metastases are found. The commonly accepted dictum reads that the smaller the breast carcinoma, the less the chances of metatstases, generally.
Most common sites of metastases:
- bone : 58%
- lung and pleura : 26%
- non-ipsilateral lymph nodes : 16%
Less frequent sites of metastases are:
In radiology practice, the most common presentation is an enlarged node in an axilla. Senology may or may not demonstrate a lesion in the ipsilateral breast. FNA of the node then shows metatstatic adenocarcimoma cells.
