A member asked:
For breast cancer can lymph nodes be tested with needle biopsy or must they 100% be removed to check them.?
A doctor has provided 1 answer
Depends on size: Larger lymph nodes that can be felt or are over 1/2" on ultrasound can be biopsied with a needle. If that shows cancer, often no further lymph node surgery is needed NOW, but might be needed later. If no lymph nodes can be felt, and none are enlarged by ultrasound, then a "Sentinel Node Biopsy" -- removing the "sentry" or guardian lymph node of the armpit is needed; sometimes more than one.
