My step-sister has beast cancer IIIc, diagnosed Nov 2011 when she was 39, had right mastectomy, axillary lymph node clearance, chemotherapy 6 cycles and radiotherapy to chest, axilla and supraclavicular area, she finished treatment in July 2012, then she went on to have a hysterectomy and bilateral salpingo-oophrectomy, her cancer is ER positive HER negative and she is on tamoxifen.
In December 2012 she found a lump in her right supraclavicular fossa. Ultrasound exam was done and her breast surgeon said it looked like a cyst or lymph node and said he would arrange for her to see her oncologist who would biopsy it if it was still there in 4 weeks. When she went to see her oncologist it was still there and he said repeat ultrasound showed enlarged lymph node but biopsy was not done.
Her oncologist is taking a watch and wait approach and my question's are;
1. in this kind of situation why would a biopsy not be done.
2. with her history does watch and wait sound like a reasonable plan?
Thank you Doctor's any thoughts would be appreciated.
