besides the "reseeding" who is to say what they are calling a lymph node in the breast area is not a new tumor? What do they mean by the breast area?
If you mean the axillary area where the breast tumors drain to, then yes, they do do US guided biopsies, but open biopsies are considered far superior. If you DO mean in the breast, then can they say with certainty it is a lymph node and not some other benign or malignant entity?

Getting a biopsy of any and everything possible would seem to make sense ie,, Right supraclavicular, Left supraclavicular and "breast area" will let you know what you are fighting so you can bring in all the best ammunition. From my readings, fine needle biopsies of axillary nodes done under ultrasound are only considered when trying preoperatively to determine if there is disease past the sentinel node--they do not catch everything as the wrong part of a node ie unaffected part may be sampled and are not considered in any way equivalent to an open biopsy

Hope this helps!
