Secondary breast cancer subpectoral lymphnode and chest wall

Just wondering if any ladies have had a biopsy on secondary breast cancer in lymphnode because they want to check to make sure its the same cancer as on chest wall. I’m on abemacilib and fulvestrant. My chest wall is stable but the one lymphnode as come back on scan as slightly enlarged from the scan before so they say treatments working but not on the one lymphnode so may have radiotherapy to blast it everything else stable.
