Local Metastasis to the IMN chain

I had an MRI done five days ago and yesterday I got the report. Not good. Actually it’s a crazy report telling me that I need 4 biopsies!! Apparently, have an enlarged axilla lymph node in a breast that never ever had cancer and still does not, according to this new report. In the other breast I have now a suspected local recurrence including a node in the IMN chain. Has anyone else here ever been told they need to get their IMNchain biopsied? Has anyone here ever been treated for a disease that lymph node in the IMN chain? There’s just not a lot out there about having a diseased lymph node in the breast itself

This is what I been able to find for a summary of what this diagnosis is:

For over a century, there has been considerable interest in the management of regional lymph node metastasis in patients with primary breast cancer. Since the advent of sentinel lymph node biopsies, there has been renewed interest in the management of patients with metastasis to the internal mammary nodes. The appropriate management of these patients has not yet been established. Some investigators propose that biopsy of the internal mammary sentinel node may provide additional prognostic information which might be used to guide the administration of systemic adjuvant therapy. Additionally, it has been suggested that patients with metastasis to the internal mammary sentinel node may benefit from radiotherapy to the internal mammary nodal chain. Clinical trials are needed to resolve these issues. Internal mammary sentinel node biopsy in patients with primary breast cancer should be considered investigational, and conducted only in the context of clinical trials.

Thanks in advance for any input shared😣
